【摘要】 基于中国283个地级城市面板数据,利用双边随机前沿模型测度了产业集聚对城市环境污染影响的促进效应、抑制效应及净效应。结果显示:产业集聚的抑制效应降低了城市环境污染41. 34%,促进效应增加了城市环境污染19. 58%;在促进效应和抑制效应共同作用下,产业集聚对城市环境污染的净效应降低了城市环境污染21. 77%;产业集聚对城市环境污染的净效应在不同年份、不同省份和不同地区均显著为负,产业集聚对城市环境污染的降低作用超过了增加作用;随着第二产业集聚水平的提高,产业集聚降低城市环境污染的净效应递减,第二产业的集聚弱化了产业集聚降低城市环境污染的作用;随着第三产业集聚水平的提高,产业集聚降低城市环境污染的净效应递增,第三产业的集聚强化了产业集聚降低城市环境污染的作用。更多还原

【Abstract】 Based on the panel data of 283 prefecture-level cities in China,this essay uses the Two-tier Stochastic Frontier Model to measure the promotion,suppression and net effects of industrial agglomeration on urban environmental pollution. The results show that: Firstly,the inhibition effect of industrial agglomeration reduces the urban environmental pollution by 41. 34%,and the promotion effect increases the urban environmental pollution by 19. 58%; Secondly,under the combined effect of promoting effect and suppressing effect,the net effect of industrial agglomeration on urban environmental pollution is to reduce urban environmental pollution by 21. 77%; Thirdly,the net effect of industrial agglomeration on urban environmental pollution is significant in different years,different provinces and different regions,indicating that the effect of industrial agglomeration on reducing urban environmental pollution exceeds the role of increasing urban environmental pollution; Forthly,as the agllomeration level rising,industrial agglomeraton has the effect of significantly reducing urban environmental pollution; Fifthly,as the third industrial agglomeration level rising,industrial agglomeraton has the effect of significantly increasing urban environmental pollution,and the third industrial agglomeration has strengthend the fact that industrial agglomeration reduces the influence of decreasing urban environment pollution.更多还原
