摘　　要：低碳城市试点政策是中国控制温室气体排放、推动经济低碳转型的重要政策。本文基于2006—2020年中国A股上市公司数据,采用多时点双重差分模型,评估低碳城市试点政策对企业环境社会责任的影响。研究结果显示,低碳城市试点政策的实施能够显著促进企业履行环境社会责任,且该结论在经过稳健性检验后依然成立。机制检验表明,试点政策通过提升绿色技术创新与绿色环保投资水平促进企业履行环境社会责任。从异质性角度看,位于高法治水平与高市场亲密程度城市的企业、高碳行业企业、国有企业、老企业与家族企业的环境社会责任表现更容易受到试点政策的影响。此外,媒体关注可以正向调节试点政策对企业环境社会责任的积极影响。本文的结论拓宽了试点政策效应评估的研究,有利于政府、企业与媒体形成绿色低碳转型合力,可以为实现环境保护与企业绩效增长相协调的可持续发展提供政策启示。The low-carbon city pilot policy is a crucial measure in China’s efforts to control greenhouse gas emissions and facilitate the transition towards a low-carbon economy.This paper uses the panel data of 894 A-share listed firms in China from 2006 to 2020 to empirically analyze the impact and mechanism of the low-carbon city pilot policy on environmental corporate social responsibility(ECSR).It employs the multi-period difference-indifferences model to assess the relationship between the low-carbon city pilot policy and ECSR.After the robustness test,the mechanism test,and the heterogeneity analysis,it examines the moderating effect of external media attention on ECSR.The findings are as follows.First,the benchmark regression analysis shows that the implementation of the lowcarbon city pilot policy can significantly promote the fulfillment of ECSR,which is still valid after robustness tests.Second,the mechanism analysis implies that the pilot policy enhances the ECSR performance by improving the level of green technology innovation and green environmental protection investment.Third,in terms of heterogeneity,the pilot policy is more likely to affect the ECSR performance of firms located in cities with high levels of rule of law and market intimacy,firms in high-carbon industries,state-owned firms,older firms,and family firms.This paper extends the evaluation of the effect of the pilot policy,which is conducive to the formation of the green and low-carbon transition synergy among the government,firms,and the media.It also provides policy insights for achieving sustainable development that coordinates environmental protection and corporate performance growth.Specifically,firms should actively respond to the low-carbon city pilot policy and integrate the green and low-carbon transition into business strategies.Green technology innovation and green environmental protection investment are important mechanisms for the pilot policy to improve ECSR.In addition,the low-carbon transition of high-carbon industries is the fo
