摘要
【目的/意义】生态补偿减排的影响机制及其效应是现有文献研究的热点问题。【设计/方法】在系统阐释生态补偿影响环境污染的内在机理、探讨“双碳”目标调节效应影响的基础上,基于长江经济带108个城市2003~2019年面板数据,采用双重差分法进行实证分析。【结论/发现】生态补偿具有降低长江经济带环境污染的效果,且这种影响具有滞后性;异质性分析表明,生态补偿对长江经济带不同区域环境污染的影响具有异质性;调节效应分析表明,“双碳”目标约束对生态补偿的污染减排效应存在正向调节作用,使用平行趋势检验、PSM-DID检验、安慰剂检验等稳健性分析后,减排效应依然成立;进一步分析表明,产业结构调整是“双碳”目标约束下生态补偿影响环境污染的中介变量。最后,从实施低碳试点与生态补偿组合政策等方面,提出促进长江经济带环境污染治理的政策建议。
[Purpose/Significance]The impact mechanism and effect of ecological compensation are hot issues in existing literature research.[Design/Methodology]This study systematically explains the inherent mechanism of ecological compensation affecting environmental pollution,discusses the impact of the Carbon Peak and Neutrality target regulation effect.Based on the panel data of 108 cities in the Yangtze River Economic Belt from 2003 to 2019,the double difference method is used for empirical analysis.[Conclusions/Findings]Ecological compensation has the effect of reducing environmental pollution in the Yangtze River Economic Belt,and this impact has a lag.Heterogeneity analysis shows that the impact of ecological compensation on environmental pollution in different regions of the Yangtze River Economic Belt is heterogeneous.The analysis of the regulatory effect shows that the pollution reduction effect of the“Carbon Peak and Neutrality”target constraint on ecological compensation has a positive regulatory effect,and the robustness analysis such as the parallel trend test,the PSMDID test,and the placebo test still exists.Further analysis shows that industrial structure adjustment is the intermediary variable of ecological compensation affecting environmental pollution under the constraint of“double carbon”target.Finally,from the implementation of low-carbon pilot and ecological compensation combination policies,policy suggestions for promoting environmental pollution control in the Yangtze River Economic Belt are put forward.
