【摘要】：本文将环境污染扩展到生产密度理论模型中,构建了一个经济集聚对污染排放强度的作用机制模型,从治污成本分摊、治污技术溢出、治污集中监管、治污的专业化分工四个方面对理论模型进行了解释。采用2002—2011年中国285个城市的数据,运用空间杜宾模型考察了经济集聚和污染排放强度间的关系及其空间依赖性。研究表明,经济集聚与单位产出的污染排放呈现倒"U"型关系,当经济集聚超过一定的临界点后,提高城市经济集聚有利于降低单位产出的污染排放强度。经济集聚的间接效应和反馈效应分别占直接效应的52.4%和40%,城市间的经济发展和环境具有明显的空间依赖特征。最后,运用广义倾向评分法分别考察了有空间依赖和无空间依赖两种情况下经济集聚对污染的影响效应差异,结果发现,经济集聚的空间依赖会对临界点产生影响,增强城市间的空间关联同样可降低单位产出的污染排放强度。
[Abstract]:This paper will be extended to the environmental pollution intensity of production in the theoretical model, constructs an economic agglomeration mechanism of pollution emission intensity from pollution model, cost sharing, technology spillover, centralized pollution control supervision, four aspects of pollution control specialization explains the theoretical model. By 2002 2011 285 the city China the data using the spatial Durbin model to examine the relationship between economic agglomeration and pollution emission intensity and its spatial dependence. The study shows that the economic agglomeration and pollution emissions per unit of output inverted "U" type, when the economy agglomeration exceeds a certain critical point, improve the city agglomeration economy is conducive to reducing pollution intensity the indirect effect of economic agglomeration and feedback effects accounted for 52.4% and 40% of the direct effect, inter city economic development and environment has obvious spatial dependence. Finally, By using the generalized propensity score were investigated with spatial dependence and spatial dependence of the two case of economic agglomeration differences, effects on pollution and found that agglomeration spatial dependence will affect the critical point, enhance the spatial correlation among the city can also reduce pollution emission intensity of a single output.
