中文摘要：

基于包含企业基本信息、地理坐标、生产以及污染物排放信息的的工业企业微观面板数据,利用东莞市环保专业基地政策这一准自然实验,采用双重差分及一系列稳健性检验,从空间和时间维度全面系统地评估了环保专业基地对企业环境绩效的影响。研究发现,基地政策提高了基地内企业环境绩效,特别在解决废水、废气、COD和氮氧排污问题的过程中成效显著;政策的辐射效应也促进了周边企业相应环境绩效的提升,且辐射随距离衰减;部分污染物对应的环境绩效在长期得到了提高;多角度检验的实证结果依然保持稳健。这意味着实施严谨、合理的环保基地政策,实现经济高增产、低污染的绿色发展模式是完全有可能的。本研究为区域性环境政策实施效果提供了微观层面的经验证据。

英文摘要：

Based on the consolidated micro panel data, we used the policy of Environmental - friendly Manufacturing Zones in Dongguan as a quasi - natural experiment, and proposed a framework including difference - in - difference method and a series of robust tests, to assess the impacts of the EMZ policy on plants＇environmental performance from the dimensions of space and time. The study found that, the EMZ policy did improve the environmental performance of plants inside the zones remarkably, especially in dealing with waste water, waste gas, COD and nitrogen oxygen pollution problems; through the radiation effect, the policy also contributed to the sun＇ounding enterprises outside the zone environmental performance improvement, and the radiation decayed with distance; in the long term, the environmental performance corresponding to some pollutants has been improved; these empirical results remain robust across statistical tests of multi - perspectives. This means that the implementation of rigorous, reasonable environmental protection policy, to a~chieve green economic development model of high production growth and low pollution, is entirely possible. This study provides a micro level empirical evidence for the effects of regional environmental policy implementation and sheds lights on the effectiveness of place-based environment regulations.
