In recent years, China had released various environmental regulations in order to respond climate change and corresponding environmental issues. However, due to imbalanced economic development and industrial structure, different Chinese regions had different enforcement levels on environmental regulations, which led to the regional transfer of pollution-intensive industries. To study the regional disparities on carbon emission transfer, this paper used the propensity score matching-difference in differences method (hereinafter abbreviated as "PSM-DID") to evaluate the mechanism between carbon trading pilot policies and the transfer of pollution-intensive industries. Panel data on 30 Chinese provinces were used to test the validity of the "pollution haven hypothesis," covering the period of 2010-2018. The empirical results showed that under the constraints of established environmental regulation, the pilot policy promoted the transfer of pollution-intensive industries to a certain extent and verified the "pollution haven hypothesis"; the proportion of the secondary sector and energy industry in the pilot areas had been reduced after the pilot policy; on the contrary, the technical level and the economic development level of the pilot provinces and cities had been further improved.
近年来，中国为应对气候变化和相应的环境问题，陆续出台了各项环境法规。但由于经济发展和产业结构的不平衡，中国各地区在环境法规的执行力度上存在差异，导致了污染密集型产业的区域性转移。为研究碳排放量转移的区域差异，本文采用倾向得分匹配-双重差分法（PSM-DID），评估了碳排放交易试点政策与污染密集型产业转移之间的作用机制。本文使用了 2010-2018 年中国 30 个省份的面板数据，检验了“污染避难所假说”的有效性。实证结果表明，在既定环境监管的约束下，试点政策在一定程度上促进了污染密集型产业的转移，验证了“污染避难所假说”；试点地区的第二产业和能源产业比重在试点政策实施后有所降低；相反，试点省份和城市的技术水平和经济发展水平进一步提高。
