摘要
两型社会政策旨在实现经济社会活动与生态环境的协调统一。基于全国281个地级市2006至2018年面板数据,在平行趋势检验前提下,采用双重差分(DID)模型,研究"两型社会"政策对城市生态环境的影响,并通过1:3半径倾向得分匹配(PSM)方法进行稳健性检验。实证结果表明:对比269个控制组地级市,"两型社会"政策能对实验组长株潭城市群和武汉城市圈("两型社会"综改区)生态环境起到明显改善作用,体现在绿地面积和空气污染、水污染治理上。
The two types of social policy aims to achieve the coordination and unity of social activities and ecological environment.Based on the panel data of 281 cities in China from 2006 to 2018,under the premise of parallel trend testing,this paper studies the impact of"the two types of social"policy on urban ecological environment by using Differences in Differences(DID)models,and conducts a robustness test by the tendency score matching(PSM)method of 1:3 radius.The empirical results show that compared with 269 control group cities,"the two-type social"policy can significantly improve the ecological environment of the experimental group leading Zhutan City Group and Wuhan City Circle("Two-type society"comprehensive reform zone.),which is reflected in green space area,air pollution and water pollution treatment.
