环境规制强化的经济增长效应与机制研究

Research on Mechanism and Effects of Stringent Environment Regulation on Economic Growth

基于中国275个地级市2004-2018年的面板数据,以环境空气质量新标准的实施为准自然试验,采用渐进双重差分方法,实证研究环境-经济双重红利效应的理论依据及实现路径。研究发现,环境规制强化能显著促进地区经济增长,结论在经过一系列稳健性检验后依然成立。并且该效应会随着地区经济水平提高而呈现边际递增的规律。机制研究发现,环境规制强化会通过增加政府公共支出、倒逼企业创新、促进公众消费及人才流入提高地区经济发展水平。

Based on the panel data of 275 prefecture-level cities from 2004 to 2018,this paper selects the policy of“Ambient Air Quality Standards(2012)”as a quasi-natural experiment,it empirically studies the theoretical basis and implementation path of environmental economic dividend effect by using the progressive DID(difference in differences)method.The results show that the strengthening of environmental regulation can significantly promote regional economic growth,which is still true after a series of robustness tests.And the effect shows an increasing quality with the improvement of regional economic level.The mechanism analysis shows that the strengthening of environmental regulation will promote the development of local economy by increasing government expenditure,improving the production efficiency of enterprises and promoting public consumption etc.
