摘　　要：二十大报告提出要加快发展方式的绿色转型,作为我国经济高质量发展的示范样板,自贸试验区始终坚持以绿色为发展底色的建设原则。基于2010-2020年我国A股上市企业数据,采用双重差分法开展自贸试验区设立对企业污染排放的准自然实验,并进一步探讨其作用路径,研究发现:(1)设立自贸试验区有利于降低企业污染排放强度,表明自贸试验区设立能够推动企业绿色转型;(2)自贸试验区的环境效应主要通过改善企业环境行为和提高企业生产率两种途径实现;(3)自贸试验区的环境效应主要体现在私营企业和轻污染行业企业,此外,相比经济发达地区,在经济较不发达地区设立自贸试验区对企业污染排放的降低幅度更大。研究结论为自贸试验区推动经济社会绿色转型提供了微观证据,对自贸试验区建设也具有政策上的启示。The report of the 20th National Congress of the Communist Party of China points out that promoting green and low-carbon development is the key to high-quality development in China.As a demonstration model of high-quality economic development,Pilot Free Trade Zones(FTZs)have always adhered to the principles of green development background during the construction process.Therefore,based on the data of Chinese A-share listed enterprises from 2010 to 2020,this paper carries out a quasi-natural experiment of the pollution emission intensity of enterprises in the FTZs by using the difference-in-differences(DID)method,and discusses its influence path.The results are as follows:(1)the establishment of FTZs is beneficial to reduce the pollution emission intensity of enterprises,indicating that the establishment of FTZs can promote the green transformation of enterprises;(2)The environmental effect of FTZs is attributed to the improvement of enterprise environmental behavior and the improvement of enterprise productivity;(3)Heterogeneity test results show that this effect is mainly reflected in private enterprises and enterprises in light pollution industries.In addition,compared with economically developed areas,the establishment of FTZs in economically less developed areas can reduce the emission intensity of pollution to a greater extent.The conclusions of the study provide micro-evidence for FTZs to promote green transformation of the economy and society,and also have policy implications for the construction of FTZs.
