[Abstract]:Based on the data of 285 cities at or above the prefectural level from 2003 to 2013, the spatial simultaneous equation is constructed, and the generalized spatial three-stage least square method is used to estimate it. This paper empirically tests the spatial spillover effect between urban spatial agglomeration density and environmental pollution. The results show that: (1) there is a significant interaction between spatial concentration density, sulfur dioxide per capita and smoke emission per capita, and (2) spatial concentration density, There is significant spatial spillover effect between per capita sulfur dioxide and per capita soot emission. (3) there is obvious spatial spillover effect between spatial concentration density and per capita sulfur dioxide and per capita soot emission. The increase of regional spatial agglomeration density is beneficial to the improvement of environmental and economic efficiency, but it intensifies the environmental pollution in the surrounding areas. (4) the influence mechanism of spatial agglomeration density on environmental pollution is heterogeneity. The increase of spatial agglomeration density can significantly reduce the emission of sulfur dioxide per capita, but there is a typical "inverted U" type development relationship between spatial agglomeration density and per capita soot emission. On the whole, although the economic growth among regions in China has shown a certain pattern of spatial linkage development, the agglomeration of spatial forces has a significant spillover effect. However, there is still a trend of "low competition" between regions in the choice of economic scale and environmental pollution. In the future, we should strengthen the construction of cooperative control mechanism on environmental pollution among different regions, and implement the measures to reduce the emission of various kinds of environmental pollutants. In addition, the market segmentation should be further broken, the free flow of elements should be realized, and the spatial agglomeration density of the whole Chinese economy should be enhanced.
