Research On The Impact Of Industrial Agglomeration On The Spatial Difference Of Environmental Pollution

For more than 40 years since the reform and opening up,China's economic development level has increased significantly,and its GDP has ranked second in the world,but at the same time,environmental pollution has also intensified.The report of China clearly stated that we must solve pressing problems immediately.Industrial agglomeration is one of the important modes of economic development at present,and exploring the impact of industrial agglomeration on environmental pollution is of great significance to China's economic development.The main content of this paper is to explore whether the development of industrial agglomeration has an aggravating or reducing effect on environmental pollution,and how to achieve the effect of continuously reducing the level of environmental pollution while increasing the level of industrial agglomeration.This paper chooses 281 cities at the local level and above in China to research.The Moran index method is used to measure the industrial agglomeration levels of China's manufacturing,productive services,and accommodation and catering industries.Using the entropy method to construct the index of environmental pollution to measure the level of environmental pollution in China,and through the construction of space panel error model,space panel self-regression model and space panel Dubin model,respectively,to explore China's manufacturing industry,productive services,accommodation,catering industry on environmental pollution.The research results show that:China's 281 prefecture-level cities and above have a positive spatial autocorrelation in the manufacturing agglomeration,productive service industry agglomeration,accommodation,catering industry,and environmental pollution index;The concentration level of manufacturing industry is related to the nonlinear curve of environmental pollution,when the concentration level of manufacturing industry is low,the positive effect of the agglomeration effect and the optimization effect of industrial structure is difficult to cancel out the negative effect steamed by diffusion effect and backward industrial structure,but when the level of manufacturing agglomeration reaches a certain level,After crossing the inflection point of the curve,manufacturing gatherings have an inhibitory effect on environmental pollution;agglomeration of productive services and environmental pollution also have a non-linear curve relationship;agglomeration of accommodation,catering industry,and environmental pollution also have a non-linear curve relationship.Therefore,the impact of industrial agglomeration on environmental pollution presents a trend,that is,the first increase and then reduce.To achieve the effect of reducing environmental pollution,it is necessary to raise the level of industrial agglomeration to cross the inflection point of the curve.
