Empirical Analysis On Central Regional County Level Economic Development And Its Pattern Considering Environment Factor

In China,the county level economy is the foundation of national economy so that it is very important for China's economic development.In particular,it is the principal part of central regional economy.The implementation of "the rise of the middle area" strategy will depend greatly on the county level economic development.Therefore, the government should accelerate the county level economic development.However, the environmental question caused by the county level economic development is more and more serious.It should attract enough attention.At present,the research on the county level economy is still very weak.The existing studies mostly rest on the simple discussion and the qualitative description of the county level economy.They have no enough systematization and depth.Especially there are few quantitative studies on the harmonious development of county level economy and environment and county level economic development pattern considering the environment factor.This article studies the economic growth,environmental stress and economic development pattern of counties in China's central region through the statistic and econometric techniques based on the economic growth theory,regional economy theory and sustainable development theory.The main studies and innovations are as follows.1.Harmonious development of county level economy and environment.This article establishes an endogenous growth model based on the environmental consumption and management,which introduces the environment as a special production factor into the production function and considers the environmental management.Furthermore,this article analyzes the balanced growth path and finds that,in the long-term view,the increase of environmental management expenditure is very important for the increase of the balanced growth rate and environmental accumulation,which are not influenced largely by the environmental management efficiency;moreover,the production rate of human capital department and R & D department and the human capital accumulation positively influence the sustainable balanced growth rate.2.Determinants of the county level economic growth in China's central region. This article examines the determinants of the county-level economic growth with the cross-country growth regression based on the pooled data of 498 counties in China's central region for the period of 2000-2006 to find out the sources of the county level economic growth.The results show that investment,human capital and urbanization are positively related with county level economic growth,while the effects of labor input,fiscal expenditure and household savings are negative.And the location and the physiognomy of counties also have remarkable influences on economic growth.Furthermore,this article develops the VAR model between the urban district and the suburban county of each capital city in central region,and analyzes the dynamic relationship through impulse response function and variance decomposition.The result shows that the suburb counties,which are influenced by the spread effect from the urban districts,have higher economic growth rates than non-suburb counties. Moreover,developing the suburb county level economy rapidly and harmoniously is vital for the development of provincial capital city.3.The environmental stress in the process of economic development.This article calculates the environment consumption of counties in central region in the process of economic growth from the five aspects,namely the energy consumption,reduction and chemization of cultivated land,industrial waste gas emission,industrial waste water emission and industrial solid wastes emission.The result shows that the counties are paying a heavy environmental expense in the process of rapid economic development.They face the stem challenges on resources consumption and pollutant emissions and have great stress of ecological environment.Then,this article evaluates the environment degradation cost through calculating the health damage cost and crop reduction cost caused by the air and water pollution based on ExtemE model,human capital approach and market price approach.The result indicates that the ecological environment has been seriously damaged.This eats into the fruit of economic growth.It is urgent to change this situation.Through the evaluation of environment governance cost,we can see that there is very low environment governance investment and very weak support for environment protection and pollution control.This is not conducive to the enhancement of environmental regeneration capability and the improvement of environment quality, and will lead to higher environment degradation cost.4.Selection and transformation of economic development patterns of counties in central region in the environmentally friendly perspective.This article proposes the new classified measure of economic development pattern according to the input and the efficiency of the production factors and divides the economic development pattern into five categories,namely external investment promotion pattern,natural resource exploiture pattern,labor economy promotion pattern,manufacturing industry agglomeration pattern and agricultural industrialization pattern.The first three patterns depend on the increase of the production factors input and the latter two patterns depend on the improvement of the production factors efficiency.This article proposes a new approach to select the economic development patterns of counties in the environmentally friendly perspective.The main path is: firstly,divide the counties into ecological counties and non-ecological counties and distinguish the economic development patterns of ecological counties in central region based on a mass of data;secondly,choose the factors influencing the selection of economic development patterns of counties,which includes the economic and social factors;finally,the economic development patterns of ecological counties are assumed as the environmentally friendly patterns and taken as the training sample. Then we establish the discriminant function to distinguish the economic development patterns of other non-ecological counties.Furthermore,we compare the current patterns with the expected of 50 non-ecological counties chosen random.The result indicates that 76%of non-ecological counties should transform the patterns.This is consistent with the truth and should be attached importance to.The method used in this article can discriminate the economic development pattern of counties well.It is helpful to solve the selection question of economic development pattern of counties considering the environment factor.Moreover,this article proposes the "integration module system" as the analysis frame to discuss the transformation of economic development pattern of counties.5.Policy support for achieving the environmentally friendly economic development.This article discusses the policy support from the economic policy and environmental policy.The following conclusions are reached.The counties in central region should adjust the industry effectively and receive sufficient talent support, fiscal support and financial support to promote the economic growth.At the same time,they should implement the environmental policy effectively to improve the sustainability and achieve the environmentally friendly economic development.
