低碳试点政策对生态福利绩效的影响

Influence of Low-carbon Pilot Policies on Ecological Welfare Performance

基于2010—2020年我国280个地级市的数据,利用SBM-DEA模型测算各城市生态福利绩效并分析其区域异质性,进而利用双重差分模型进行实证检验,探究低碳试点政策对生态福利绩效的影响。研究结果显示,低碳试点政策对提升生态福利绩效有积极影响。该结论通过稳健性检验,生态福利绩效总体呈上升趋势,且西部地区最高,中部地区次之,东北地区最低。

Based on the data of 280 prefecture-level cities in China from 2010 to 2020,the study measures the ecological welfare performance of each city,analyzes its regional heterogeneity with SBM-DEA model,conducts empirical test with differential differential model,and explores the influence of low-carbon pilot policies on ecological welfare performance.The results show that low-carbon pilot policies positively influence the improvement of ecological welfare performance.After a series of robustness tests,the conclusion is still valid.Ecological welfare performance is on the rise in general.The western region is the highest,followed by the central region,and the northeast region is the lowest.
