Industrial Agglomeration Externalities, City Size, and Regional Economic Development： Empirical Research Based on Dynamic Panel Data of 283 Cities and GMM Method

Local governments have long been ardently pursuing the industrial specialization effect(MAR externalities) and industrial diversification effect(Jacobs externalities). Such a pursuit has resulted in severe distortion of resource allocation and negative effect on sustainability of local economic development. Regarding the effect from both MAR and Jacobs externalities on local economic development existing literature records notable disputes. Therefore, for local economic development, one important issue is which externality(MAR or Jacobs) can better bring the effect into play. By studying a panel data of 283 Chinese cities from 2003 to 2012 and applying dynamic plane data GMM method, this paper conducted a regression analysis of the relationship among industrial agglomeration externalities, city size, and regional economic development. The result indicates that with regard to the whole nation, MAR externalities are conducive to regional economy development whereas Jacobs externalities will, to an extent, restrain regional economic development. As regards eastern, middle, and western regions, MAR externalities are conducive only to the economic development of the eastern region; their effects on middle and western regions are insignificant. Moreover, the interaction item between MAR externalities and city size has a significant negative synergistic effect on national economic development and a certain acceleration effect on eastern region as well as a strong negative synergistic effect on the middle region and an insignificant effect on the western region. The interaction item between Jacobs externalities and city size has a positive synergistic effect on only the middle region and has an insignificant synergistic effect on both eastern and western regions. Capital stock and labor input have significant accelerating effects on GDP growth per capita of Chinese cities, whereas material capital and labor input remain primary driving forces for Chinese local economic development. Furthermore, human capital contributes to accelerating urban economic development, whereas government intervention restrains urban economic development.

Regional Distribution and Sustainable Development Strategy of Mineral Resources in China

This paper summarizes the distribution and production layout of the major mineral resources in China,including coal,iron ore,copper and bauxite,from a national perspective.It also identifies the incompatibility between the mineral resources distribution and regional economic development.Significant issues with China's mineral resource industry cause challenges for the sustainable development of both the mining industry and the national socio-economy.The sustainability of regional mineral resources and the environmental pollution by mining in the western China were also analyzed.Results show that the distribution of China's mineral resources is misaligned with its regional layout of economic development.China's mineral resources have been over-exploited,and the mineral resources production in the eastern China is unsustainable.The continuously expanding production of mineral resources in the western China has heavily endangered the ecological environment.We propose strategies to boost the sustainable development of mineral resources,including measures to accelerate economic development and enhance the sustainability of domestic mineral resources.We also offer suggestions for scientifically planning the mineral resource prospecting and exploitation and regional economic layout,as well as for proactively undertaking industry transfer in the eastern China and raising the environmental benchmark requirements for the mineral industry in the central and western China.

Dynamic Changes,Regional Differences,and Influencing Factorsof CO_2 Emission Performance in China

This paper proposes to use DEA models with undesirable outputs to construct the Malmquist index that can be use to investigate the dynamic changes of CO 2 emission performance.With the index,the authors have measured the CO 2 emission performance of 28 provinces and autonomous regions in China from 1996 to 2007;with the convergence theory and panel data regression model,the authors analyze the regional differences and the influencing factors.It is found that the performance of CO 2 emissions in China has been continuously improved mainly due to the technological progress,and the average improvement rate is 3.25%,with a cumulative improvement rate of 40.86%.In addition,the CO 2 emission performance varies across four regions.As a whole,the performance score of eastern China is the highest.The northeastern and central China has relatively lower performance scores,and the western China is relatively backward.The regional differences are decreasing,and the performance of CO 2 emissions is convergent.The influence of some factors on the performance of CO 2 emissions is significant,such as the level of economic development,the level of industrial structure,energy intensity,and ownership structure.The influence of some factors,such as opening-up to the outside world,on the performance of CO 2 emissions is not significant..

Main Factors on Energy Efficiency in East China during 1995-2010： An Analysis Based on the SBM-Tobit Model

Applying the slacks-based measure （SBM）-Tobit two-stage model, this paper analyzes energy efficiency in eastern China. First, the SBM model featured in taking non- desired output in calculation was employed to evaluate the energy efficiency in eastern China from 1995 to 2010. The results show that Tianjin, Shanghai and Guangdong have the highest energy efficiency while Hebei has the lowest. Next, we used the panel Tobit model to perform a regression on factors affecting energy efficiency. Our results show that optimizing industrial structure, improving energy structure and enhancing the level of economic reform can contribute to improving energy efficiency. Government influence and technological progress, on the other hand, affect energy efficiency insignificantly. The influence of socio-economic development on the energy efficiency goes from negative to positive, which adheres to the Kuznets curve hypothesis. Our findings are that the socio-economic development in eastern China has not yet passed the ＂turning point of the Kuznets curve ＂.

The Flying Geese Paradigm:Industrial Upgrade Strategy and Balanced Regional Development

On the basis of competency-based comparative advantage theory and reclassification of industries,this paper has discussed whether the FGP-type industry upgrade has taken place across different regions of China and whether China is able to transcend the middle-income trap through the FGP-type industry upgrade.This paper has discovered that no matter by traditional method of industry classification or the new method of industry classification,China has already experienced the FGP-type industry upgrade and entered into the second stage of this process.While relocating industries to central and western regions,China's eastern region does not have clear directions of industry upgrade of its own.Through analysis on the evolution of comparative advantages across regions,this paper has also discovered that in the process of the FGP industry upgrade,China is facing the risk of falling into comparative advantage trap.These factors are unfavorable to China's implementation of the FGP-type industry upgrade strategy,prevention of the comparative advantage interruptions that may confront middle-income countries and achievement of balanced regional development.

Philosophical Consideration about the Sustainable Development of the Economy in West China

To realize the sustainable development of the economy of West China is not merely a great economic problem, butalso a great national problem and political issue. The economic activity is a practical activity for the economic subject. Theeconomic development view, values, and the natural view of the economic subject determine the choice of the behavior of themain body in the economic activity. Only the behavior of the economic subject according with its demands could make theeconomy of west China have a sustainable development. Therefore, establishing the development view, the values and naturalview of the economic subject for sustainable development becomes a realistic problem that is worth of thinking.

Rapid growth of industrial nitrogen fluxes in China: Driving forces and consequences

Human activities are strongly modifying the global nitrogen (N) cycle through increasing input, N species diversity, and pool size of industrial reactive N (Nr). However, the fluxes, fates and environmental consequences of industrial Nr (excluding synthesized N fertilizer) remain poorly understood and quantified. We report here that industrial Nr flux has increased 13.4-fold over the past 30 years in China, reaching 3.7Tg N (1 Tg=10 12g) in 2008, accounting for over 50% of China's food Nr flux. Socioeconomic development (per capita GDP, urbanization and household size) significantly drives the growth of industrial Nr fluxes. This leads to "hotspots" of industrial Nr, mainly in relatively developed Eastern China. Industrial Nr loss rate during production is only 5%, much lower than that of cropland (50%) and livestock (80%). However, industrial Nr loss is point source pollution, and Nr release in concentrated doses produces serious risk in small regions. The contribution of structural N to total industrial Nr with a lifespan longer than one year (e.g., synthetic fiber, plastic) increased from 20% in 1980 to 70% in 2008. There was about 2.6 Tg N structural industrial Nr accumulated in human settlements in 2008, which could be one ex- planation of an unknown Nr sink of anthropogenic Nr input (mainly Haber-Bosch N fixation). Legacy effects caused by structural N accumulation have long-term consequences for environmental and human health, although structural N delays Nr release and reduces short-term Nr pollution. Industrial Nr use generates new features of modern global N biogeochemistry, such as increasing Nr species diversity, reducing Nr turnover rate. Future dynamics simulation of the earth system should involve industrial Nr. Explicit consideration and accounting of the fluxes and environmental consequences of industrial Nr would provide decision-makers a novel view of regional sustainable development.

The Yangtze River’s Development Swells

Coordinated regional development has long been a focus of the Chinese Government.For instance,over the past few decades,the government has rolled out the western region development plan as well as its strategy of revitalizing northeast China.It has also developed economic zones in regions such as the west coast of the Taiwan Straits and the Yangtze River Delta.At present,another such regional development zone,
