摘要
本文选取了中国1999—2010年31个省市区的面板数据为分析样本,构建面板数据联立方程模型,分别从全国层面和东、中、西部三大地区层面,实证研究了产业集聚对环境污染的影响。结果发现,产业集聚有利于降低环境污染程度,产业集聚并不是近年来环境污染和生态破坏加剧的原因;对外开放程度对环境污染的影响显著为负,从整体上来看,"污染避难所"假说在中国并不成立;产业集聚的正向环境外部性效应存在显著的区域差异,对东部地区环境污染的改善作用大于中西部地区。在此基础上,运用两步系统广义矩估计法进行稳健性检验,发现产业集聚对环境污染具有正U形影响,且二者关系处于U形曲线的下降通道中,因此,产业集聚达到一定程度时将有助于改善环境污染。
This paper selects the panel data from Chinese 31 provinces during the 1999 2010 as sam ples for analysis and establishes panel data simultaneous equations model. The paper investigates the effect of industrial agglomeration on the pollution environment from the national level and the eastern, central and west ern regions. The results show that industrial agglomeration is beneficial to reduce the degree of the environment pollution. It shows that industrial agglomeration doesn＇ t aggravate environmental pollution and ecology de stroys in recent years. The level of opening up has a significantly negative influence on the environmental pollution. In general, the ＂pollution haven＂ hypothesis does not hold in China. The positive environmental externality effect of industrial agglomeration has a significantly difference with region. The improvement of en vironmental pollution in the eastern region is greater than that of central and western regions. Based on this, this paper uses two step system of generalized moment estimation method to test the robustness of results and then finds that, industrial agglomeration has a U shaped effect on environmental pollution, and the relation ship between them is in downward path of the U shaped curve. Therefore, industry agglomeration is benefi cial for improving Chinese environmental pollution.
