环境规制政策的碳减排效应研究

Research on the Carbon Emission Reduction Effect of Environmental Regulatory Policies

摘要: 21世纪以来，为了应对日趋严重的环境问题，各项环境规制政策开始相继出台，本文选取了其中的碳排放权交易试点政策，探究环境规制政策的碳减排效应。将碳排放权交易试点政策作为一项准自然实验，利用2005年到2020年中国29个省市的面板数据，使用双重差分方法进行了实证分析，探讨了碳排放权交易试点政策的碳减排效应。实证研究结果表明：碳排放权交易试点政策对于试点省市有显著的碳减排效应，并且通过更换样本区间以及安慰剂检验的方式进一步验证了实证结论的稳健性。

Abstract: Since the beginning of the 21st century, in order to cope with the increasingly serious environmental problems, various environmental regulatory policies have begun to be introduced one after another, and this paper selects the pilot policies of carbon emission trading to explore the carbon emission reduction effects of environmental regulatory policies. Taking the carbon emissions trading pilot policy as a quasi-natural experiment, using the panel data of 29 provinces and cities in China from 2005 to 2020, the DID is used to conduct empirical analysis to explore the carbon emission reduction effect of the carbon emission reduction policy of the carbon emission trading pilot policy. The empirical results show that the pilot policy of carbon emission trading has a significant carbon emission reduction effect on the pilot provinces and cities, and the robustness of the empirical conclusions is further verified by changing the sample interval and placebo testing.
