环境规制对区域经济高质量发展的影响——基于双重差分法的实证研究

Environmental Regulation and High Quality Development of Regional Economy:An Empirical Research Based on Difference-in-Differences Method

基于2005—2017年太湖流域两省地级及以上城市的面板数据,采用双重差分方法(Difference-in-Differences)评估了国家加强地区环境管制对该地区经济发展质量的影响,并运用合成控制法对政策影响的异质性进行了进一步验证。结论表明,环境管制显著降低了整个区域的环境污染,并同时改善了产业结构,提升了城市的经济水平。但是对于发展程度不同的城市的影响存在异质性,对于大中规模城市有正向影响,对于小规模城市有负向影响。总体来说,《太湖流域管理条例》这一环境管制政策显著促进了太湖流域经济的高质量发展。

Based on the panel data of two provinces and cities above the level of Taihu Basin in 2005-2017,the Differences-in-Differences method was used to evaluate the national environmental regulation on this area.The influence of regional economic development quality and the heterogeneity of policy influence are further verified by using the Synthetic Control Method.The conclusion shows that environmental regulation can significantly reduce the pollution of the whole region,improve the industrial structure and improve the economic level of the whole region,but the impact on different cities has heterogeneity,positive impact on large and medium-sized cities,and negative impact on small cities.In general,the implementation of Taihu Basin management regulations promotes the high-quality development of Taihu Basin economy.
