This study analyzes the potential for energy savings by identifying inefficiencies in electricity use and their determinants in the Japanese industrial sector. Specifically, we used stochastic frontier analysis to estimate inefficiencies in electricity consumption based on data obtained from electric power companies. We identified significant determinants of electricity consumption efficiency and that changes in national energy policy following the Great East Japan Earthquake changed electricity consumption behavior. The contribution of this study is that its findings can be used to improve the cost-effectiveness of policies aimed at improving energy efficiency.

This study analyzed the efficiency of residential electricity demands from 1990 to 2015 across the electrical supply regions of Japan. Specifically, I utilized a stochastic frontier analysis to statistically identify the determinants of the efficiency of residential electricity demands. The analysis revealed that a decline in average household size improves the efficiency of electricity demands, whereas a rise in the aging of household members worsens it. Furthermore, this study showed that the efficiency of electricity demands improves in warmer regions because of increased cost consciousness in cooling demands, whereas it deteriorates in colder regions because of the complementary use of various heating devices. A shift in Japan’s energy policy following the 2011 Great East Japan Earthquake has not significantly affected the efficiency of residential electricity demands. In other words, no structural changes have occurred in the efficiency of electricity demands during the observation period. As such, long-term trends within this sector in Japan include a decline in the average household size and a rise in population aging. Therefore, these findings provide important insights into Japan’s future trends in terms of energy demands.

Energy intensity improvement is an influential policy agenda for global environmental problem-solving and sustainability enhancement. This study focuses on inter-regional networks’ impact on energy intensity and statistically examines whether the improvement of such networks promotes a modal shift from passenger vehicles to railways. The results indicate the nonlinear relationship between the improvement of inter-regional networks and the variation of the passenger vehicle sector’s energy consumption. Furthermore, the results reveal that the laying of high-speed railways, which helps strengthen inter-regional networks, can significantly improve regional energy intensity. This result has valuable implications for Japan’s national land plan. The high-quality transportation infrastructure, such as high-speed railways, to be introduced in the country can potentially change the energy consumption patterns in inter-regional travel and improve energy intensity. Our results suggest that the installation of the high-speed railway will effectively reduce carbon dioxide emissions. This revelation is expected to provide new policy evidence to scholars and policymakers.

This chapter analyzes the relationship between inter-regional network economies and regional disparities using stochastic frontier analysis. The current dynamics in Japan’s regional economic systems reveal a monocentric concentration in the Greater Tokyo Area. When the lock-in effect of agglomeration occurs, economic disparities between large metropolitan areas and local areas should expand. However, in Japan, regional disparities have not increased. Instead, economic performance in local areas has improved, and economic disparities between large metropolitan areas and local areas are narrowing. Therefore, Japan’s situation requires an explanation that goes beyond conventional agglomeration theory. This chapter shows that inter-regional networks enhance the effectiveness of borrowed size and repair the lost links between regional economic systems and agglomeration theory. The chapter reveals that the borrowed size effect has significantly improved production efficiency in local areas in Japan. The impact of the borrowed size effect is greater than the agglomeration benefit derived from the local size. The results also show that the development of high-quality transportation networks has enabled local areas to catch up to large metropolitan areas and reduce regional disparities. This suggests that the establishment of high-quality inter-regional networks is a significant policy measure to help reduce regional disparities in Japan’s economy.

This chapter provides an overview of the contents of this book. This book discusses the impacts of inter-regional networks on the regional economy through economic analyses. This book also has many implications for the national land policy in Japan. Japan’s national land plan aims to achieve enormous economic benefits through the upgrading of inter-regional networks. Connecting regions via high-speed transportation networks may help to improve regional productivity and environmental efficiency. However, to the best of our knowledge, few studies have assessed the significance of the national land plan because of the low availability of relevant data and the scarcity of analytical methods for accurately measuring inter-regional network economies. Therefore, this book provides analytical methods that can clarify the role of inter-regional networks in improving productivity and environmental efficiency. Based on plentiful empirical evidence, this book defines the role of inter-regional networks in the regional economy. Notably, the book provides indicators that capture the economic effects of inter-regional networks. Using these indicators reveals that such networks enhance geographical externalities in regions and improve productivity and environmental efficiency. These findings provide readers with guidelines regarding desirable regional economic policies for economies facing population decline.

For the society of population decline, improving productivity is crucial for achieving regional sustainability. This chapter presents the concept of inter-regional network economies as a new paradigm for agglomeration economies and clarifies the effect of high-speed transportation networks on total factor productivity (TFP) by using Japan’s regional data. The results show that inter-regional networks contribute more to TFP growth in many regions than regional agglomeration does. The development of high-quality transportation networks has promoted the inter-regional flow of economic agents. By increasing opportunities for interaction, these inter-regional flows increase knowledge spillovers between regions. That is, connecting cities through high-quality transportation networks and strengthening their connections with each other will lead to significant spillover from agglomeration economies, previously restricted to cities, to other regions. The results of this chapter confirm that high-quality transportation networks spread the economic benefits of agglomeration across a broader area through the effect of borrowed size. It can be concluded that measures for the development of high-quality transportation networks are essential for regional sustainability in the sense of expanding geographical externalities.

This chapter considers the determinants of Japan’s regional TFP. An increase in TFP can be achieved through two paths: The first is a shift in the production frontier, which amounts to an increase in output for a given input volume (productivity effect). The second is an approach to the production frontier by ensuring that outputs are closer to the production frontier levels for a given input volume (productive efficiency effect). The elements of external economies, such as social overhead capital (SOC) and regional agglomeration, affect both. From these two paths, this chapter clarifies the roles played by SOC and regional agglomeration in increasing regional sustainability by using the stochastic frontier model of the TFP index. The empirical analysis using Japan’s regional data provides the following evidence. First, SOC investment contributes to TFP growth and, more importantly, has a productivity effect and productive efficiency effect, mainly in local areas. Second, regional agglomeration underpins the TFP growth in large metropolitan areas. Third, the productive efficiency effect is high in regions specializing in internationally competitive manufacturing industries. It is concluded that providing high-quality public infrastructure and enhancing regional productivity are essential strategies for the government to consider in its efforts to achieve sustainable regional growth.

This chapter measures the total factor productivity (TFP) in Japan’s regions and clarifies whether a convergence of TFP disparities has been observed since 1980. Japan’s regional economies face global competition amid the challenges of a declining and aging population. Given these economic conditions, the Japanese government has sought to boost TFP to enhance sustainability in regional economies. This chapter measures TFP using Japanese regional data. Most of Japan’s studies measure TFP at the national level; few studies attempt TFP analysis in a regional context. Therefore, this chapter contributes to TFP research in the context of regional economies. Furthermore, this chapter introduces a stochastic convergence model to verify the regional convergence. In Japan’s study, cross-sectional studies show regional convergence, while some time-series studies do not show convergence. Therefore, another objective of this chapter is to provide additional evidence to supplement the discussions of previous studies. The results of this chapter reveal that Japan’s TFP has not only continually increased over the study period but has also reduced regional disparities. Furthermore, the results show that TFP converged to each region’s steady-state level rather than the national level. These results suggest the significance of regional production environments and provide policy implications for regional economies.

This chapter provides an overview of the regional economic structure. Japan continues to experience migration and a spatial concentration of economic activities in the Greater Tokyo Area. The theory on agglomeration economies explains that this population inflow enhances the Greater Tokyo Area’s increasing returns to scale. In other words, as population inflow in the Greater Tokyo Area increases its economies of scale, the gaps in the economic performance between the Greater Tokyo Area and local areas are expected to widen, and the regional disparities in gross value added (GVA) per capita should expand. However, regional disparities in GVA per capita have been shrinking rather than expanding since the 1990s. Conventional theories do not explain this phenomenon well. This chapter provides evidence of economic growth in local areas and the potential for economic advance. Notably, this chapter reveals that social overhead capital, industrial structure, and fiscal transfer have enhanced the economic power of local areas and helped reduce regional disparities. Japan’s experiences provide valuable insights into regional development policies aimed at achieving compatibility between economic growth and equitability.

This chapter reevaluates inter-regional network economies in Japan based on cost-based Solow residuals, a novel analytical approach. In most studies, inter-regional network economies have been measured as elements of technological progress in production functions. However, the conventional approach based on perfect competition raises concerns that measurements of geographical externalities depend on the behavior of economic agents. One way to mitigate this concern is to construct a model based on imperfect competition. The cost-share Solow residual approach provides reliable evidence of the geographical externalities uncovered by the conventional approach. That is, by applying this approach to geographical analysis, we can precisely identify inter-regional network economies under imperfect economies. Furthermore, by using this approach, we perform a sensitivity analysis on the installation of the Linear-Chuo Shinkansen (magnetic levitation train) to measure the economic impact of high-quality transportation infrastructure. The results show that the Linear-Chuo Shinkansen provides a significant time-saving effect not only in the region of origin but also in local regions other than those along the railway lines. That is, the results reveal that the formation of inter-regional networks can increase productivity not only in large metropolitan areas but also in local areas. The results of this chapter suggest that inter-regional networks via high-quality transportation infrastructure significantly enhance regional economic performance. This chapter provides empirical evidence for the national land plan in Japan.

Energy conservation is a crucial policy agenda for solving global environmental problems and enhancing sustainability. This chapter quantifies the possibility of decreasing energy consumption in the passenger vehicle sector by improving inter-regional networks and provides a way to realize sustainable development goals (SDGs). The efficient design of high-speed transportation networks enables economic agents to avoid using private vehicles, which saves transportation energy. The results reveal a nonlinear relationship between improvements in inter-regional networks and reduced energy consumption in the passenger vehicle sector. There is an inverse U-shaped relationship between the two. That is, a modal shift from passenger vehicles to railways occurs if the improvement in the regional network reaches a threshold value. Furthermore, this chapter clarifies the changes in energy consumption patterns due to the installation of the Linear-Chuo Shinkansen, a high-speed magnetic levitation train. The Linear-Chuo Shinkansen has the potential to improve both firm productivity and energy efficiency because firms facing environmental constraints can invest in energy conservation by increasing their profits. Notably, the Linear-Chuo Shinkansen can drive a modal shift from passenger vehicles to railways, thereby improving the energy efficiency of the regions. Through a sensitivity analysis, this chapter shows that the Linear-Chuo Shinkansen installation has the potential to switch the mode of inter-regional travel from passenger vehicles to railways. These results suggest that the installation of the new high-speed railway leads to a reduction in greenhouse gas emissions and is a trump card to achieve SDGs.

Energy intensity has not been deemed a suitable index of energy efficiency because it depends on various socioeconomic factors, such as energy prices and production size. Therefore, this chapter identifies desirable energy efficiency indices that overcome the concerns of energy intensity using the stochastic frontier analysis (SFA) approach. The SFA approach controls for prices and income, mechanization, vintage, and climate factors to derive accurate energy efficiency levels. By using this approach, this chapter clarifies the energy efficiency level for Japan’s industrial and commercial sectors and evaluates the impact of regional agglomeration and inter-regional networks on energy efficiency. The results reveal that improved inter-regional networks have a positive impact on energy efficiency. Regions with well-developed transportation networks are highly energy efficient. This result suggests that policies aimed at strengthening inter-regional networks can significantly contribute to improving energy efficiency in Japan. Meanwhile, the results reveal that regional agglomeration has mixed effects on energy efficiency. That is, there are positive and negative impacts on energy efficiency. Initially, agglomeration economies inherently have a mixture of advantages and disadvantages, such as spatial externalities, congestion, and heat islands. By considering the nonlinear effects, this chapter identified that there is a threshold in the agglomeration effects, and both a positive and negative effect of agglomeration are at play. This result suggests that agglomeration sizes beyond the threshold level are necessary to enjoy agglomeration benefits.

Controlling greenhouse gas emissions by improving energy intensity and boosting regional economic growth are essential policy goals for realizing regional sustainability. Given the potential conflicts between these goals, this chapter examines whether regional agglomeration, which is considered a driving force for productivity improvement, contributes to improved energy intensity. Originally, regional agglomeration was considered to enhance productivity and competitiveness via knowledge spillover. Spillover effects, wherein advances in one firm’s efficiency spread rapidly to other firms, lower the overall cost threshold for improvements in energy efficiency. In other words, the regional agglomeration has the potential to improve energy efficiency. The results of this chapter demonstrate the significant effect of regional agglomeration on energy intensity. Notably, it was confirmed that regional agglomeration affects not only regional disparities in energy intensity but also temporal dynamic changes. This finding suggests that differences in regional agglomeration affect energy demand patterns via energy intensity. Furthermore, this chapter clarifies the regional disparities in the agglomeration effect on energy intensity. The local area specialized in the manufacturing industry has a more significant potential to improve energy intensity than the large metropolitan area. These results highlight the importance of regional agglomeration as a primary factor in energy intensity and suggest that regional agglomeration should be encouraged in regions to improve energy intensity, which could protect the environment while fostering economic growth.

This study evaluates the regional agglomeration and the inter‐regional network economies in Japan based on cost‐based Solow residuals, overcoming the issues associated with the conventional analytical approaches. Furthermore, this study performs a simulation analysis of the economic impacts of the Linear Chuo Shinkansen (magnetic levitation train) to investigate the role of high‐quality transportation infrastructure in regional sustainability. The results reveal that the improvement of inter‐regional networks increases regional productivity. Furthermore, the results reveal that the economic benefits of inter‐regional networks extend beyond railroad lines. These results suggest that inter‐regional networks via high‐quality transportation infrastructure enhance regional economic performance.

With the growing demand for energy, improving energy efficiency has become a key policy issue in Japan. Therefore, this study estimates the energy demand function of Japan’s industrial sector using a stochastic frontier model and analyzes the level of energy efficiency and its determinants. An empirical analysis based on the data of 47 Japanese prefectures presents three main findings. First, installment in large production facilities deteriorates energy efficiency and second, it is effective in increasing the electrification rate to improve energy efficiency. Finally, improving productivity leads to an increase in the electrification rate. These results suggest that policies aimed at increasing electrification by enhancing the productivity of factories and offices significantly contribute to improving energy efficiency.

In the Japanese economy, complying with environmental regulations while achieving a balance between greenhouse gas emissions and regional economic growth is an important policy issue. From the perspective of national land policy, spatial agglomeration of populations is a potential solution to this issue. This study clarifies whether population agglomeration, which is a source of economic growth, contributes to the improvement of energy intensity in the residential and industrial sectors by using a dynamic panel model. The use of this model enables a simultaneous understanding of the short- and long-term effects of population agglomeration on energy intensity. The results of the analysis reveal that population agglomeration influences improvements in energy intensity. Specifically, over the observation period, population agglomeration improved energy intensity in large metropolitan areas, including the Greater Tokyo area and the Chubu and Kansai regions. In contrast, for less urbanized areas, population dispersion exacerbated energy intensity. These results suggest that forming population agglomerations will lead to improvement in energy efficiency. That is, they suggest that a compact city policy that agglomerates populations in city centers may be effective in improving energy efficiency across Japan.

Traditional agglomeration theories cannot explain Japan's sustained reduction of regional disparities. This study employs stochastic frontier analysis to investigate the role of inter‐regional networks in improving productive efficiency using the concept of “borrowed size.” Improved inter‐regional networks are a driving force for strengthening local economies and converging regional disparities. Borrowed size from large city agglomeration was highly effective in local areas. The development of transportation networks has enabled local areas to catch up to large metropolitan areas. The results suggest that the development of high‐speed transportation networks can help to reduce regional disparities in the Japanese economy.

A better understanding of the price mechanisms behind electricity demand fluctuations could help develop effective tools to forecast energy demand after natural disasters. To this end, this study empirically analyzed the price elasticity of residential electricity demand in Japan over the 1990–2015 period using regional data. In particular, it attempted to shed light on the price mechanisms behind demand fluctuations by analyzing the effects of both price increases and decreases on power demand. The results showed that households tend to consume electricity according to past patterns. Given this electricity consumption behavior, once the habit of saving electricity is established, it persists. The results also show that changes in the power supply configuration associated with natural disasters may alter people’s electricity consumption behaviors. Consumer responses seem to be more sensitive to price rises than to price falls. This suggests the possibility that residential electricity demand will further decrease if the trend of rising electricity rates continues in the future.

This study investigates the impact of population agglomeration and interregional networks on the energy efficiency of the Japanese industrial and commercial sector. The empirical analysis employs a stochastic frontier model and reveals a nonlinear relation between population agglomeration and energy efficiency. External diseconomies prevail until reaching a threshold level of agglomeration; when the threshold is exceeded, external economies come into play. Enhanced accessibility is found to significantly increase energy efficiency. These results suggest that policies aimed at strengthening regional agglomeration and interregional networks can greatly contribute to improving energy efficiency.

This study examines the productivity growth and its four components for Japanese regional economies by analyzing 47 prefectures for the period 1995–2012. The productivity changes are measured by the Hicks–Moorsteen–Bjurek productivity growth, and the four components consist of technical change, efficiency change, scale change, and input and output mix effects. Data envelopment analysis (DEA) is applied to the measurement. From the results, this study provides two policy recommendations for Japan’s new economic growth strategy, which are associated with (1) government support for the diffusion of advanced technology over regions and (2) the creation and development of unique innovation by regional industries.

With Japan’s declining population, improving productivity is important to achieving continuous regional economic growth. This study focuses on the regional effects of population agglomeration and accessibility on total factor productivity (TFP). Empirical analysis shows that population agglomeration contributed to TFP growth, most significantly in the Greater Tokyo area. The interaction (flow) of people was examined and the importance of high-speed transportation network for TFP growth was clarified as the effect of accessibility on TFP growth. Population agglomeration and the development of transportation network are thus important strategies for growing regional economies.

Controlling the rapid growth of residential energy demand and enhancing energy efficiency are key policy issues in Japan. Thus, this study aims to estimate a residential energy demand function by conducting a stochastic frontier analysis and analyze the regional determinants of energy efficiency. The results indicate that population density and electrification rate foster energy efficiency and exert the same degree of impact. The study also highlights that population concentration has a nonlinear effect on energy efficiency. In other words, when combined with population concentration, the promotion of electrification policies can significantly contribute toward improving energy efficiency in the residential sector and consequently, have a positive effect on Japan’s regional economy.

In the Japanese economy facing environmental restrictions, both the control of greenhouse gas emissions and the boost of regional economic growth are important policy issues. In this context, this study employs econometric methods to investigate whether population agglomeration, which is a potential source of economic growth, contributes to the reduction of energy consumption in the residential sector. The results of the analysis highlight that population agglomeration affects savings in energy consumption. Specifically, over the considered observation period, population agglomeration has saved energy consumption in large metropolitan areas. In contrast, in rural areas, population dispersion has had the opposite effect.

This chapter aims to describe an up-to-date approach of analyzing the electricity demand and to estimate electricity demand functions in Japan’s industrial, commercial, and residential sectors. This chapter employs the dynamic GMM estimation approach and empirically analyzes regional electricity demand by using panel data on 47 Japanese prefectures. The results reveal that the price elasticity of residential electricity demand is high compared with income elasticity, implying that residential electricity demand changes with rates. On the other hand, the results also reveal that in industrial and commercial sectors, the price elasticity of demand is extremely low in the short and long run and production elasticity is greater than price elasticity. Thus, price elasticity is a key determinant in residential electricity demand fluctuations but not a determinant in industrial and commercial electricity demand fluctuations. Furthermore, an analysis of factors influencing electricity demand shows that increasing residential electricity demand growth in each region can be attributable mainly to declining electricity rates and increasing the number of households. The analysis also suggests that the declining industrial electricity demand growth in large metropolitan areas is mainly attributable to declining production factors, not increasing electricity rates. By contrast, the commercial sector is experiencing an increasing demand for electricity and significant growth nationwide, which can be attributed to an increase in commercial floor space and advances in office automation. These results suggest that monitoring the electricity rates is important for forecasting future residential electricity demand at region.

Background
Rapidly increasing residential electricity demand has made raising energy efficiency an important policy issue in controlling electricity demand.

Methods
This study uses a stochastic frontier model to estimate the residential electricity demand function and analyse electricity energy efficiency levels and their determinants using regional data on Japan.

Results
The results confirm the importance of household dwelling types for determining the electricity energy efficiency. Specifically, the findings suggest that household size and floor area are key to electricity savings, but the ageing Japanese society shows a limited relationship with electricity savings. Further, promoting living in areas where the population has aggregated also results in electricity savings.

Conclusions
The findings suggest that forming urbanised cities and realising multi-polarisation-type national spatial developments might improve electricity energy efficiency and stimulate regional economies.

This chapter examines the impacts of agglomeration economies and fiscal transfer on productive efficiency in Japanese regional industries. Two popular methodologies, stochastic frontier analysis and data envelopment analysis, are applied to measure productive efficiency. The empirical findings are summarized as follows: (1) Agglomeration economies improve productive efficiency. (2) Fiscal transfer negatively influences productive efficiency. (3) Those two findings are observed for aggregated manufacturing and non-manufacturing industries, and for sectors in manufacturing industries. (4) The importance of agglomeration economies for regional industries has increased in recent years. Based on these results, this chapter discusses effective regional policy for Japan.

This chapter describes the research background three objectives of this book. The first objective is to clarify from multiple perspectives how industrial agglomeration influenced the growth of the regional economy in Japan during the 1980s and 1990s, when globalization of economic activity and the hollowing-out of industries were in progress. The second is to shed light on the industrial agglomeration effects from a dynamic perspective by looking at industrial development. The third objective is to propose a new analytical approach using the techniques of productive efficiency analysis. This book is comprised of ten chapters. A summary of each chapter is described in this chapter.

This chapter focuses on dynamic externalities that are a source of competitive advantages, and reviews the related empirical studies. Research on technical-knowledge spillover, the core of dynamic externalities, is being widely conducted, mainly in the field of industrial organization theory. However, there are few empirical studies that have considered technical-knowledge spillover from the viewpoint of industrial agglomeration. Some studies estimate the extent and type of dynamic externalities, and find evidence consistent with dynamic externalities. Despite the different data sources used, methodologies are similar. This chapter reviews the main methodologies of dynamic externalities, and discusses empirical analysis issues of previous studies.

This chapter proposes a new approach to measure agglomeration economies in Japan. Specifically, this study employs the Solow residual to confirm whether agglomeration economies exist in both manufacturing and non-manufacturing industries. This study also shows that social overhead capital has a positive effect on agglomeration economies. Currently, such economies are robust only in large metropolitan areas; however, they are present throughout Japan because of the disproportionate allocation of social overhead capital within the country.

This chapter sheds empirical light on the relationship between agglomeration economies and regional economic growth and the impact of that relationship on the convergence of regional disparities in productivity, using a traditional approach to agglomeration economies. Based on Japanese prefectural data, an empirical analysis indicates that agglomeration economies have significant effects on regional economic growth. Furthermore, agglomeration economies contribute to economic convergence in the manufacturing industry, while they contribute to increasing disparities across regions in the non-manufacturing industry. These results suggest that an increase in the proportion of non-manufacturing industries has the potential to create regional disparities.

This chapter details the role of industrial agglomeration in regional economies, and discusses the issues found in existing empirical studies. The role industrial agglomeration plays in regional economies has been discussed and empirically studied for a long time. Agglomerations include several related industries, and an abundance of specialized workers. Therefore, it is possible for firms to achieve high productivity through input sharing, labor market pooling, and knowledge spillovers. Such effects can generally be found in two cases: The first case is where an agglomeration of similar industries results in an increase in productivity. The second case is where an agglomeration of different industries results in an increase in productivity. Traditionally, these effects have been measured by external economies of scale, but an analytical approach has recently been proposed that uses spatial density to seek the source of external economies. This chapter reviews these research trends.

This chapter examines whether agglomeration economies, market access, and public fiscal transfer have a positive or negative influence on the productive efficiency of Japanese regional industries. To accomplish the research objective, this chapter applies stochastic frontier analysis to a prefecture level Japanese data set that consists of estimated spatial and industrial economic activities. An empirical result obtained in this chapter indicates that both agglomeration economies and the improvement of market access have a positive influence on the productive efficiency of Japanese manufacturing and non-manufacturing industries. In contrast, public fiscal transfer has a negative impact on productive efficiency. These findings indicate that many prefectures that are characterized by weak market access and/or high dependence on public fiscal transfer are often associated with low productive efficiency.

This chapter examines the effects of industrial agglomeration on productivity growth in emerging industries. The analysis employs four-digit data of Japanese manufacturing industries, and shows that (1) ceramic, stone, and clay products, general machinery, and precision instruments and machinery enjoy the advantage generated by proximity to other industries; (2) new manufacturing technology sectors, such as industrial robots, tend to receive agglomeration effects, although information technology sectors do not; and (3) most emerging industries do not profit from economies of scale. These findings reveal that emerging industries benefit from agglomeration effects and face market competition.

This chapter investigates how dynamic externalities promote industrial growth in Japanese manufacturing industries. In contrast to previous studies, this study characterizes dynamic externalities by total factor productivity. Using panel data of Japanese prefectures from 1985 through 2000, this study finds evidence of localization (MAR) externalities and urbanization (Jacobs) externalities. However, this study does not find clear evidence that dynamic externalities play the role of centripetal forces for industrial location.

This chapter analyzes the determinants of regional variations in new firm formation by industry, using the data of 47 prefectures in Japan. The results of this study reveal the following findings: (1) market access is the factor that promotes new firm formation in all industries, although the impact on new firm formation is greater in the service industry than in the manufacturing industry; (2) industrial agglomeration contributes to stimulating new firm formation in the manufacturing industry; and (3) while average wage is an important factor in the manufacturing industry, it is not significant in the service industry.

The Japanese economy must contend with environmental restrictions; hence, both controlling greenhouse gas emissions by improving energy intensity and boosting national and regional economic growth are important policy goals. Given the potential conflicts between these goals, this study investigates the current energy consumption levels in the Japanese regional economy to determine the factors contributing to improvements in energy intensity. We conduct an empirical analysis using econometric methods to examine whether population density, which is considered a driving force of productivity improvements, contributes to improved energy intensity. The analysis results reveal that population density influences energy intensity improvements. However, the impact differs across regions. In large metropolitan areas, population agglomeration has improved energy intensity, whereas in rural areas, population dispersion has worsened it. The policy implication from this study is that population agglomeration should be encouraged in each region to improve energy intensity, which could protect the environment along with future economic growth.

As Japan’s birthrate declines and its society ages, governmental policies need to improve the productivity of regional economies in order to sustain regional growth. This study examines social overhead capital and population agglomeration as drivers of total factor productivity (TFP) growth in Japan. The use of stochastic frontier analysis demonstrates that social overhead capital contributes to TFP growth and, especially, influences productive efficiency. Furthermore, the findings reveal that population agglomeration underpins TFP growth in regional economies. Empirical results also indicate that productive efficiency is high in regions where manufacturing is concentrated and that productive efficiency improves when internationally competitive manufacturers concentrate in regional economies. This study endorses the development of social overhead capital to spur Japan’s regional TFP growth. As such, it indicates that providing social infrastructure and enhancing regional productivity are important strategies for the government to consider in its efforts to achieve sustainable regional growth.

Purpose: This paper aims to estimate electricity demand functions in Japan’s residential sector. Design/methodology/approach: The authors use a partial adjustment model and empirically analyze regional residential electricity demand by using data on 47 Japanese prefectures. Findings: The results reveal that the price elasticity of residential electricity demand during the analytical period (1990-2010) is remarkably different among prefectures, depending on the magnitude of floor space per household. In addition, this study finds that price elasticity is high compared with income elasticity, implying that residential electricity demand changes with rates. Furthermore, an analysis of factors influencing electricity demand in the residential sector shows that increasing electricity demand growth in each region can be attributable mainly to declining electricity rates and increasing number of households. Research limitations/implications: These results suggest that monitoring the electricity rates and the number of households is important for forecasting future residential electricity demand at region. Originality/value: The study considers the impact of the number of households on overall electricity demand and identifies other factors contributing to growth in residential electricity demand. The findings can be used to derive projections for future electricity demand.

In order to investigate the future trends of energy demand in Japan accurately, there is a need to clarify the factors that cause fluctuations in energy demand across regions; more specifically, to determine whether the energy demand fluctuations across regions arise from compositional factors, that is, differences in energy users, or from regionally unique factors. This study analyzes the determinants of energy demand change to clarify the factors that have affected the fluctuations in regional energy demands in Japan, using dynamic shift-share analysis. The results show that the energy demand fluctuations can be explained by both compositional effects and regional effects. With regard to the compositional effects, the energy demand growth increased most remarkably in the regions that specialize in residential and commercial sectors. However, energy demand did not increase in the regions that specialize in manufacturing sectors. With respect to the regional effects, there were constraints on energy demand in large metropolitan areas due to the improved energy intensity achieved through energy conservation. The results imply that having a mixture of industry and ResCom (Residential and Commercial) sectors in a region potentially flattens out fluctuations in energy demand changes. This finding suggests that when moderating changes in regional energy demand, an important step is to diversify the industrial structure in each region.

In this study, the Energy Consumption Statistics by Prefecture were utilized and the actual conditions of energy demand in the regions of Japan were ascertained. The results revealed that Japan’s national energy demand increased from the 1990s to the 2000s; and that the driving forces behind this expansion were the Residential and Commercial (ResCom) and Transportation sectors. In regional trends, the findings showed that the increase in energy demand in large metropolitan areas not only contributed greatly to the national increase, but also that energy demand in rural areas grew steadily. Upon considering the changes to regional energy demand by analyzing changes to energy demand per capita and population changes, the study found that energy demand per capita has a major impact on regional energy demand, and that in particular, the increase in energy demand in rural regions has been brought about by the increase in energy demand per capita.

Based on the rapid increase in residential energy demand, the question of how to raise energy efficiency in the residential sector, while controlling overall demand, is an important policy issue for Japan. In this study, the stochastic frontier model is used to estimate the energy demand function in the residential sector and to analyze the energy efficiency levels and their factors. From the results of the empirical analysis based on regional data in Japan, the following three points were clarified. First, the energy efficiency levels calculated using the stochastic frontier model were highly correlated with the energy intensity levels and are effective as an index expressing energy efficiency. Second, raising the regions’ electrification rates is an effective way of improving energy efficiency in the residential sector. Third, increasing the regions’ population densities is also an effective way of improving energy efficiency in the residential sector. These findings suggest that not only will implementing policies to advance electrification contribute greatly to improving environmental efficiency in the residential sector, but also that realizing decentralized, multi-polar national spatial developments may improve environmental efficiency and stimulate regional economies.

In response to increased environmental constraints, it has become an important policy issue for Japan to improve energy efficiency for the future, along with the growth of regional economies. This study uses a stochastic frontier model to estimate the energy demand function and analyze the levels and determinants of energy efficiency. The empirical analysis, conducted by using data from 47 prefectures in Japan, revealed the following four findings. First, the proposed energy efficiency measure (calculated using the stochastic frontier model) is found valid, as its ranking is highly correlated with that of energy intensity. Second, increasing population density is effective in improving energy efficiency. Third, improving regional accessibility by developing a highway network helps to improve energy efficiency in Japan. Fourth, the level of energy efficiency is deteriorating in areas where raw material industries are clustered. These results indicate that the means to increasing both economic productivity and environmental efficiency are to implement a regional decentralization policy by creating major urban areas across the nation and expand a wide-area transportation network to link these areas. In addition, the promotion of technological innovations through appropriate environmental regulations is important to advance such regional policies.

Along with various environmental concerns, Japan has an important policy issue arising from the development of its economy, which is how simultaneously to attain regional economic growth and energy efficiency. This study examined the impacts of agglomeration economies on energy efficiency of Japanese manufacturing industries. Using a prefecture-level panel data set from the Energy Consumption Statistics by Prefecture, this study reveals the following three empirical findings. First, productivity growth has improved energy efficiency, but not vice versa. Second, agglomeration economies, which are a driving force for productivity growth, have improved the energy efficiency of Japanese manufacturing industries. Finally, by agglomerating similar industries, localization economies are effective in improving energy efficiency in rural areas. The third finding is consistent with many previous studies claiming that agglomeration economies based on localization occur for many medium-sized cities. The result implies that an important policy direction for Japan will be to formulate medium-sized cities in rural areas than large metropolitan cities in terms of improving the energy efficiency of manufacturing industries.

Background
To investigate the future trends of energy demand in Japan accurately, it is necessary to clarify the factors that determine the fluctuations in energy demands across regions. Specifically, it is necessary to clarify whether the energy demand fluctuations across regions arise from compositional factors, that is, differences in energy users, or from regionally unique factors.

Methods
This study analyzes the determinants of energy demand change to clarify the factors that have affected the fluctuations in regional energy demands in Japan, using dynamic shift-share analysis.

Results
The results show that the energy demand fluctuations can be explained by compositional effects and regional effects. With regard to the compositional effects, the energy demand growth increased most remarkably in the regions that specialize in residential and commercial activities. However, energy demand did not increase in the regions that specialize in manufacturing activities. With respect to the regional effects, there were constraints on energy demand in big-city regions because of the improved energy intensity achieved through energy conservation.

Conclusions
The results imply that having a mixture of industry and civil sector activities in a region potentially flattens out the fluctuations in energy demand changes. This finding suggests that when moderating the change of regional energy demand, it is important to diversify the industrial structure in each region.

In a Japanese economy that must contend with environmental restrictions, both the control of greenhouse gas emissions by improving energy efficiency and the boosting of national and regional economic growth are important issues of policy. To this end, this study targeted the industrial sectors of 47 prefectures and investigated the current energy consumption levels for the manufacturing industry in order to analyze the factors contributing to improvements in energy efficiency in the manufacturing industry, which is responsible for most of the industrial energy consumed. An empirical analysis was conducted using econometric methods to determine whether an improvement in energy efficiency is compatible with an improvement in productivity and/or whether industrial agglomeration, in which productivity improvement is the driving force, contributes to an improvement in energy efficiency.
The results of the analysis are as follows. (1) There is a clear correlation between productivity and energy efficiency. A deeper analysis of this correlation reveals that while productivity improvement influences energy efficiency, an improvement in energy efficiency does not influence productivity improvement. (2) Industrial agglomeration influences improvements in energy efficiency. Industrial agglomeration has improved energy efficiency from the formation of industry agglomeration in rural regions. In contract, in the Tokyo metropolitan area and Kansai region, the decline in industrial agglomeration has worsened energy efficiency. This result suggests that in order to improve our manufacturing energy efficiency, it is necessary to agglomerate the same type of industries in rural regions.

Japan’s regional economies face global competition amidst the challenges of a declining and aging population. Given such economic conditions, Japan’s total factor productivity (TFP) requires boosting to achieve competitiveness in regional economies. Although labor productivity is a popular measure for the analysis of productivity and has been a focus of prior studies, TFP’s comprehensiveness is a preferable measure. This study measures TFP using regional data from Japan and tests if the convergence of regional TFP disparities can be detected since 1980. The results show that TFP has continually increased and converged to reduce regional disparities over the study period. We perform statistical analysis of the regional convergence in TFP using a stochastic convergence model and find that TFP converged at each region’s stationary level, not at the nationwide unique level. These results provide policy implications for Japan’s regional economies.

With environmental constraints being strengthened worldwide, an important question that arises for Japan’s economic policy is how best to achieve regional economic growth along with energy efficiency. This study examines the impacts of agglomeration economies, which boost economic growth, on the energy efficiency of Japanese manufacturing industries. Using a prefectural-level panel dataset from the Energy Consumption Statistics by Prefecture, this study obtains new empirical results: (1) agglomeration economies improve the energy efficiency of Japanese manufacturing industries; (2) localization economies positively impact the improvement of energy efficiency in rural areas, while urbanization economies positively impact the improvement of energy efficiency in large metropolitan areas. Thus, it is determined that agglomerating similar industries is effective in improving energy efficiency in rural areas; however, in large metropolitan areas, it is more effective to agglomerate diverse industries in order to improve energy efficiency. In general, industrial agglomeration as a result of economies of agglomeration, based on localization, occurs for the most part in medium-sized cities. The finding therefore suggests that it is more appropriate to formulate strategy in terms of medium-sized cities than large metropolitan cities in improving the energy efficiency of manufacturing industries located in rural areas.

This study examines productivity change and the factors of regional industries in Japan using a data set consisting of 47 prefectures over the period from 1990 to 2009. The data set is comprised of one output and five inputs for manufacturing and non-manufacturing industries; amount of real term production as an output and intermediate input, number of employees, private capital stock, social capital stock and final energy consumption as inputs. Using the data set, we measure Hicks-Moorsteen-Bjurek (HMB) productivity index proposed by Nemoto and Goto (2005). The advantage of the HMB productivity index compared with the other popular productivity indexes such as Törnqvist productivity index and Malmquist productivity index is that the former can be fully decomposed into factors to explain the productivity change over time. To calculate the HMB productivity index, this study measures the distance functions by applying a data envelopment analysis (DEA). From the results, this study indicates regional disparity has gradually expanded among regions, particularly after 2003. We show the increased disparity can be attributed to the reduced level of social capital investment for rural areas since 2000’s. Finally this study discusses desirable regional policy in Japan.

This study aims to estimate electricity demand functions in Japan’s industrial and commercial sectors. We adopt data from the Energy Consumption Statistics by Prefecture by the Ministry of Economy, Trade and Industry, Japan, to delineate the demand between the industrial and commercial sector. The results reveal that in both sectors, the price elasticity of demand is extremely low in the short and long run and production elasticity is greater than price elasticity. Thus, price elasticity is not a key determinant in electricity demand fluctuations. Furthermore, an analysis of the factors influencing changes in electricity demand in the industrial sector suggests that the declining demand growth in large metropolitan areas is mainly attributable to declining production factors, not increasing electricity rates. By contrast, the commercial sector is experiencing an increasing demand for electricity and significant growth nationwide, which can be attributed to an increase in commercial floor space and advances in office automation.

This paper examines the impacts of agglomeration economies and fiscal transfer on productive efficiency in Japanese regional industries. Two popular methodologies are applied - stochastic frontier analysis (SFA) and data envelopment analysis (DEA) - to measure productive efficiency. The empirical findings are summarized as follows: (1) agglomeration economies improve productive efficiency; (2) fiscal transfer negatively influences productive efficiency; (3) those two findings are observed for aggregated manufacturing and non-manufacturing industries, and for sectors in manufacturing industries; and (4) the importance of agglomeration economies for regional industries has increased in recent years. Based on these results, this paper discusses effective regional policy for Japan.

Stochastic frontier analysis is used to examine the cost-efficiency of Japanese local governments at a prefectural level, corresponding to states in the United States. The issue of cost-efficiency has two policy concerns for fiscal decentralization: one is whether fiscal transfers from central government to local governments influence cost-efficiency; the other is whether the size of the local population influences cost-efficiency. This study empirically confirms that the fiscal transfers have a negative effect. In contrast, population size has a positive effect. The two findings may suggest that Japanese local governments can improve their cost-efficiencies by both reducing the amount of fiscal transfers via decentralization and increasing a population growth via regional integration.

This study derivates the empirical models of residential and power demand and attempts to measure the price elasticity of residential and power demand among nine power companies. As the general consensus among researchers analyzing electric demand is that electric power demand is extremely inelastic; the price elasticity of electric demand is a priori assumed to be as low as zero or –0.1. The results of the empirical analysis reveal that the values for the price elasticity of residential demand in each region are distributed between –0.14 and –0.64; therefore, it is clear that price elasticity significantly varies from zero in all regions. Further, since the price elasticity values of power demand are between –0.16 and –0.55, it is apparent that these values also significantly vary from zero in all regions. Regional disparities for residential demand were also found. Moreover, we can confirm that a feature of regional power demand is that price elasticity is smaller in urban areas and larger in rural areas. It is understood that power demand is related to the ratio of self-owned power plants.

本稿では新たに男女別・年齢別の転出者数と転入者数が地域間で整合し、地域間移動を経済格差や移動動態で説明した人口モデルを開発することで、2050年までの中国地域の長期人口予測を行った。年齢別の転出率を考慮したモデルからは、今後進展する少子高齢化により人口変動において社会増減が縮小し、自然減が支配的になることが示された。さらに、高度成長期に人口が多く流入した広島県では今後20年間で高齢者数が24％も増加するとともに、自然減の規模が徐々に拡大していくことが示された。また、2005～2010年の転入超過率を一定と仮定したモデルを採用している他機関の推計と比較すると、他機関の推計が悲観的な予測値であることが明らかとなった。さらに、出生率の変動は各地域の2050年時点の人口に対して1割ほどの規模で影響を与えることがわかった。

A balance between industrial pollution and economic growth becomes a major policy issue to attain a sustainable society in the world. To discuss the problem from economics and business perspectives, this study proposes a new use of DEA (Data Envelopment Analysis) as a methodology for unified (operational and environmental) assessment. A unique feature of the proposed approach is that it separates outputs into desirable and undesirable categories. Such separation is important because energy industries usually produce both desirable and undesirable outputs. This study discusses how to unify the two types of outputs under natural and managerial disposability. The proposed DEA approach evaluates various organizations by the three efficiency measures such as OE (Operational Efficiency), UEN (Unified Efficiency under Natural disposability) and UENM (Unified Efficiency under Natural and Managerial disposability). An important feature of UENM is that it separates inputs into two categories and unifies them under the two disposability concepts in addition to the proposed output separation and unification. This study incorporates an amount of capital assets for technology innovation, as one of the two input group, into the measurement of UENM. Then, it compares UENM with the other two efficiency measures. This study is the first research effort in which DEA has an analytical capability to quantify the importance of investment on capital assets for technology innovation. To confirm the practicality of the proposed approach, this study applies the three efficiency measures to a data set regarding manufacturing and non-manufacturing industries of 47 prefectures in Japan. This study empirically confirms the validity of Porter hypothesis in Japanese manufacturing industries, so implying that environmental regulation has been effective for betterment on the performance of Japanese manufacturing industries. Another important finding is that the emission of greenhouse gases is a main source of unified inefficiency in the two groups of industries. Therefore, Japanese industries, examined in this study, need to make their efforts to reduce the greenhouse gas emissions and air pollution substances by investing in capital assets for technology innovation.

In this study, we conducted an empirical analysis of the impacts of social overhead capital, population agglomeration and industry structure on productive efficiency, focusing on Japan’s 47 prefectures. The analysis results showed that upgrading social overhead capital contributes to improved regional productive efficiency. At the same time, the economic effect of population agglomeration was clearly shown to increase productive efficiency. Moreover, regions that are heavily weighted toward manufacturing were shown to have high productive efficiency. <br>After investigating the degree to which each factor contributes to productivity gains in each region, it became clear that the largest contributor was industry structure. In other words, the transformation of industry structure appears to be indispensable for the sustainable development of regional economies. At the same time, upgrading social overhead capital was shown to contribute to some degree to such sustainable development. Meanwhile, high population agglomeration appeared to have a powerful economic effect in major metropolitan areas, such as Tokyo Metropolitan Area and Kansai. Due to its significant external effect, population agglomeration is predicted to realize economies of scale in Tokyo and Osaka. <br>This study demonstrated that upgrading social overhead capital has an effect on increasing productive efficiency, in addition to previously understood effects on productivity. Upgrading regional social overhead capital drives sustainable growth in regional economies through increases in productivity. Future studies should address regional analysis at a more detailed level, such as at the level of municipalities.<br><br>JEL Classification: R11, R30, R38

This study quantifies the factors contributing to foreign direct investment (FDI) using data from a questionnaire-based survey of Japanese manufacturing firms with overseas operations. The results of our analysis echoed that of previous research, demonstrating that in addition to company size, the effects of R and marketing capabilities on FDI were statistically significant. Notably, R capability exerted a stronger effect than marketing capability, which led us to conclude that technical knowledge is an important firm-specific advantage among firms embarking on FDI.

The global warming and climate change becomes a major policy issue in the world. To partly deal with the climate change issue from economics and business concerns, this study proposes a use of Data Envelopment Analysis (DEA) as a methodology for unified (operational and environmental) assessments. The proposed DEA approach has been long serving as an important methodology to evaluate the performance of various organizations. Recently, many researchers have applied DEA to various environmental issues. A contribution of the previous DEA studies was that they found the importance of an output separation into desirable (good) outputs and undesirable (bad) outputs (e.g., CO2 emission and air pollution substances from production activities). Acknowledging a contribution of these previous studies on DEA environmental assessment, this study classifies efficiency measures into the two categories according to the treatment of undesirable outputs: (a) productive efficiency and (b) unified efficiency under natural disposability. The first efficiency does not incorporate undesirable outputs in the performance evaluation, while the second measure incorporates them to the environmental assessment. Using a data set regarding the manufacturing industries of 47 prefectures in Japan, this study examines their productive and environmental efficiencies to obtain policy implications. The important empirical finding suggests that Japanese regional industries need to make their further efforts to reduce air pollution substances and increase energy efficiency.

経済活動のグローバル化が進む中、人口減少等の供給制約要因が経済成長の妨げになることが懸念されているわが国の地域経済においては、生産性の向上に対する期待は高い。そこで、地域経済の生産性の向上に重要な役割を果たす産業集積に着目し、今後の地域経済の発展を考える視点として産業集積の経済効果を検証した。とりわけ、中国地域に着目し、中国地域における産業成長に対する産業集積の寄与について定量的に検証した。その結果は次の通りである。まず、労働生産性に対する産業集積効果の影響は、製造業、非製造業ともに、異業種集積効果である都市化の経済が同業種集積効果である地域特化の経済を上回る傾向にあることが明らかとなった。しかしながら、産業成長に対する寄与では、製造業、非製造業ともに、地域特化の経済の影響が都市化の経済の影響を上回り、地域特化の経済が産業成長の原動力だったことも明らかとなった。次に、製造業業種別の分析を行った結果、地域特化の経済と都市化の経済が顕在化している業種は異なることを示す結果が得られた。最後に、この結果をもとに、中国地域における産業成長に対する産業集積効果の違いを検討した結果、中国地域では化学と電気機械において地域特化の経済の成長寄与度が高いことが明らかとなった。その一方で、中国地域全体では人口密度が低下している影響から、大半の業種で都市化の経済が成長の足を引っ張る結果となった。

This study examines whether agglomeration economies, market access and public fiscal transfer have a positive or negative influence on the productive efficiency of Japanese regional industries. To attain the research objective, stochastic frontier analysis is applied to a Japanese data set at a prefecture level which consists of estimated spatial and industrial economic activities from 1980 to 2002. An empirical result obtained in this study indicates that both the agglomeration economies and the improvement of market access have a positive influence on the productive efficiency of Japanese manufacturing and non-manufacturing industries. In contrast, the public fiscal transfer has a negative impact on the productive efficiency. These findings indicate that many prefectures (corresponding to States in the United States), which are characterized by weak market access and/or high dependence on public fiscal transfer, are often associated with their low productive efficiency.

This paper sheds empirical light on the relationship between industrial agglomeration economies and the convergence of the regional disparities in productivity. An empirical analysis, based on Japanese prefectural data for the period 1980–2002, shows that industrial agglomeration has significant effects on labor productivity. Furthermore, industrial agglomeration contributes to economic convergence in the manufacturing industry, while it contributes to increasing disparities across regions in the non-manufacturing industry. These results suggest that an increase in the share of non-manufacturing sectors has the potential to create such regional disparities.

This paper analyzes the determinants of regional variations in new firm formation by industry, using the data of 47 prefectures in Japan. The results of this paper reveal the following evidences: (1) market access is the factor that promotes new firm formation in all industries, though the impact on new firm formation is greater in the service sectors than in the manufacturing sectors; (2) the industrial agglomeration contributes to stimulating new firm formation in the manufacturing sectors; and (3) while average wage is an important factor in the manufacturing sectors, it is not significant in the service sectors.

本稿では地域経済・産業の成長に果たす産業集積の役割を明らかにすることを目的として、1980年代と1990年代を中心に、47都道府県の製造業と非製造業という産業区分のもと、1）産業集積がどの程度地域経済・産業の成長に貢献したのか、2）産業集積が地域産業の生産性を向上させることで、結果として労働生産性の地域間格差収束に寄与したかどうかの2点を分析し、次の結果を得た。
まず、製造業では産業集積効果である規模の経済性が観察され、その成長寄与度は製造業が集中立地する中部、東北、北関東の各県において相対的に大であることが明らかとなった。一方、非製造業では規模の経済性の影響が埼玉、千葉、東京、神奈川といった首都圏地域で大であることも明らかとなった。さらに、地域間スピルオーバーの影響は、製造業と非製造業のどちらの産業においても規模の経済性の影響を超過しており、それが両産業の生産活動において重要な役割を果たしたことを示す結果が得られた。
次に、地域間の生産性格差収束に対する産業集積の影響を検証した結果、製造業では地方への資本移転と工場誘致による生産基盤の強化により、規模の経済性が生産性格差を収束させる方向で作用する一方、非製造業では規模の経済性が生産性格差を拡大させる方向に働いたことを示す結果が得られた。これらの結果は、製造業では各地域において優位な分野に生産集中させることが地域間の生産性格差収束につながる一方、非製造業では首都圏への経済活動の一極集中が、産業集積の影響等を通じて地域間の生産性格差を拡大させる可能性を持つことを示唆している。

少子・高齢化、グローバル化など激しい社会・経済の変動にさらされている地域において、これからの地域経済をどう再構築し維持していくのか、その将来ビジョンを描くことの重要性が高まっている。そこで本稿では、中長期を対象とした中国地域マクロ経済の変動と産業構造の変化を同時に見通すことが可能な中国地域計量経済・産業連関モデルの開発を行った。これは『平成12年中国地域内産業連関表』(経済産業省)を基礎に、地域内32部門別産出額および粗付加価値額、民間最終消費、民間住宅投資、民間設備投資などの地域内需要、さらに地域内で生み出される所得などを整合的に把握しうるモデルである。同モデルの特徴は、需給動向を反映して投入構造が内生的に変化するというメカニズムを有する点にある。同モデルを用いて中国地域経済における2030年までの経済予測を行った結果、中国地域の実質経済成長率は年率平均で0.93%とほぼ全国(0.94%)並みに推移する結果が得られた。人口減少により域内需要は低い伸びにとどまるものの、中国地域経済が基盤とする化学、石油・石炭製品、鉄鋼、一般機械、電気機械、輸送機械などの産業において域外需要牽引型の成長が予測される。

新規開業の促進は、地域の保有する資源を活かした内発的な産業振興策のひとつとして注目され、重要な政策課題となっている。地域において新規開業を効果的に促進していくためには、開業に影響を与える地域要因を把握し、それを踏まえた対応が求められる。国内の先行研究では開業要因の産業別差異に着目した研究が少ないことから、本論文において新たに製造業とサービス業との比較を中心とする定量分析を行った。その結果、製造業とサービス業の両産業において需要規模が開業率に対して正の影響を与えることが明らかになる一方、製造業では需要成長の影響が弱くコスト要因が負の影響を与えること、サービス業では集積効果の影響が強まっていることなど産業固有の特徴も明らかになった。さらに我々はサービス業の個別業種を取り上げ、分析を行った結果、専門サービスでは同業種集積が、事業サービスでは異業種集積が開業に強い影響を及ぼす傾向にあることを示す結果を得た。この結果はサービス経済化が進展していく中、人口や事業所が集積し、集積効果が期待される大都市地域とこれらの効果が期待できない地方との間で開業格差が拡大する可能性が高いことを示唆している。

This paper reviews existing literature on dynamic externalities which is the fountainhead of competitive advantages, and argues that rigorous theoretical and empirical analysis is needed to increase understanding of the role of technological spillovers in generating regional growth. Empirical analysis of knowledge spillovers is broadly performed in the field of industrial organization. Recently, a number of empirical analyses aiming at verifying technological spillovers accompanying R&D activity of companies have been conducted. In recent empirical literature on spatial agglomeration, many papers find evidence consistent with dynamic externalities. Especially, growing bodies of research have estimated the extent and type of dynamic externalities. Despite the different data sources used, methodologies are similar. As the survey of some methodologies has been carried out by McDonald (1997), this paper reviews the main empirical analyses of dynamic externalities as the complement−positioning.

料金値上げによる電力需要への影響を分析するため、電力9社（沖縄電力を除く）の管内を対象とし、電気事業連合会の電力需要実績を用いて電灯・電力需要の価格弾力性（需要の変化率を価格の変化率で割ったもの）に関する実証分析を行った。この結果、価格弾力性はこれまでのような無視できるほどの低水準ではなく、例えば、電灯では-0.17（北海道）から-0.66（北陸）、電力では-0.16（東京）から-0.55（北陸）など 、地域間で有意な差があることが明らかになった。電気料金の値上げによる電力需要の影響は小さくなく、従来のように全国の価格弾力性だけを見ていると、各地域の的確な需要見通しができない可能性があることを示した。
