| Since China's reform and opening up,the trend of industrial agglomeration is gradually obvious,and formed a number,technological effects,to promote the expansion of the scale of the industry and the scale of enterprises But the agglomeration area characteristic industry vigorous development may also have unfavorable factors restrict and affect the sustainable development of economy,such as industrial agglomeration brings in a lot of capital accumulation and,also contributed to the consumption of resources,cause environmental pollution problems,especially industrial agglomeration negative externality may cause pollution to the environment;and environment problem.With the outstanding environmental problems,to realize the sustainable development of economy,pollution reduction has become an inevitable choice.Therefore,it is of strategic significance t and to provide decision-making basis for the scientific development and environmental optimization of industrial agglomeration.Through it is to enhance the degree of agglomeration and exert the effect of agglomeration economy,it can achieve the goal of improving the environment and realizing the coordinated development of economy and environment.Through reasonable guide the transfer of industries to prevent the negative effects caused by too high concentration of external diseconomies of scale of economic development,to achieve the purpose of promoting the sustainable development of economy.This paper attempts to China's manufacturing industry for the analysis of the sample,and selected industrial sulfur dioxide emissions as an indicator of environmental pollution,respectively from the industry level construct static and dynamic panel data and using threshold regression model to analyze the manufacturing industry agglomeration effects to the environment pollution.First of all,combined with the industry agglomeration in scale,technology and structure at different stages of the positive and negative externalities,the interpretation of industry agglomeration mechanism of the effects of environmental pollution,and starting from the Cobb Douglas production function,push the export production enterprises and sewage decision-making and analysis of industrial agglomeration from the scale effect,technology effect and structural effect to the pollution of the environment have an impact.Secondly,to our country manufacturing industry agglomeration level is described,found Chinese manufacturing industry agglomeration level in low concentration,but the overall upward trend.Again,of manufacturing industry of our country environmental pollution situation described found that accounts for the total pollutant emission amount is the largest,followed by the labor-intensive industry,emissions are relatively less technology intensive industries,but will be eased.Finally,including the construction of industrial agglomeration,technology,size and other factors,the dual threshold regression model,from the industry level study manufacture agglomeration in the effect of different development stages and other control variables to the pollution of the environment.Empirical and industrial agglomeration the relationship between the level is between the two turning points in the N type curve,and the majority of China's manufacturing industry,Can not let me accompany you to go,the development of the industry can not be separated from the support of the people.With the continuous improvement of the political system,the direction of democracy is becoming more and more clear,we can do is to do their own thing,follow the feeling.environment pollution and agglomeration of the relationship between the level has crossed the n-shaped curve a turning point in the first but did not reach the second turning point.Based on the above conclusion,China should strengthen the development of industrial agglomeration should also reasonable industrial layout.The agglomeration and the environment coordinated development put forward the corresponding policy recommendations. |
