摘　　要：低碳城市试点政策是促进企业绿色创新的重要途径,然而,既有研究探讨低碳城市试点政策对绿色创新影响的较为少见,难以为企业绿色转型提供有效借鉴。为此,该研究将低碳城市试点政策作为一项准自然试验,基于2007—2020年中国936家A股上市公司的面板数据,运用多期双重差分和三重差分模型,实证分析低碳城市试点政策对企业绿色创新的影响及其企业规模、产权性质和碳排放行业异质性,进而从环境责任和人才集聚视角探讨这一政策促进企业绿色创新的中介传导机制,确定低碳城市试点政策效应发挥的最优路径。研究结果表明:①低碳城市试点政策有效推动了试点地区企业绿色创新,与绿色实用新型专利创新相比,该试点政策对绿色发明专利创新的影响更为显著,通过PSM‑DID、安慰剂检验等一系列稳健性检验,发现结论依然成立。②低碳城市试点政策对绿色创新的影响具有企业规模、产权性质和碳排放行业异质性,这一政策对大规模企业的政策效应更为明显,且仅对国有企业实用新型专利具有积极影响,而对非国有企业不同程度绿色创新均具有显著积极影响,低碳城市试点政策对高碳行业企业绿色创新的积极效应明显,而对低碳行业企业绿色创新起到一定抑制作用。③低碳城市试点政策促进企业绿色创新的主要传导机制在于通过加强企业环境信息披露管理、提升企业环保投资水平以及提供企业环保政府支持来增强企业环境责任意识,通过吸引就业人才、地方高校人才和企业高技术人才而诱发人才集聚效应;从传导路径效应比较来看,环境责任的影响更大,其次是人才集聚。因此,政府可继续扩大低碳城市政策试点范围,给予中小科技型民营企业和绿色环保类企业更多的财政和政策支持,推动国企股份制改造和兼并重组,对高碳排放企业给予持续环境管制与�The low-carbon city pilot policy is an important way to promote corporate green innovation,and it is also an inevitable choice to achieve the goals of achieving peak carbon emissions and carbon neutrality.However,existing research on the impact of the low-carbon city pilot policy on green innovation lacks depth,and literature focusing on micro-corporate level is insufficient.Therefore,it is difficult to provide an effective reference for corporate green transformation.Based on the panel data of 936 A-share listed companies in China from 2007 to 2020,this paper took the low-carbon city pilot policy as a quasi-natural experiment.The multistage dynamic difference-in-differences model and difference-in-difference-in-differences model were used to explore the impact of the low-carbon city pilot policy on corporate green innovation and its heterogeneity in terms of enterprise size,property rights,and carbon emission industry.Furthermore,from the perspective of environmental responsibility and talent agglomeration,this paper discussed the transmission mechanism of this policy to promote corporate green innovation and determined the optimal path for the low-carbon city pilot policy to take.The research results showed that:①The low-carbon city pilot policy effectively promoted corporate green innovation in the pilot areas.Compared with the green utility model patent innovation,the pilot policy had a more significant impact on green invention patent innovation.A series of robustness tests such as PSM-DID and the placebo test found that the conclusion was still valid.②The impact of the low-carbon city pilot policy on green innovation presented heterogeneity in terms of enterprise size,property rights,and carbon emission industry.This policy had a more significant policy impact on large-scale enterprises,and only had a positive impact on the utility model patent of state-owned enterprises but had a significant positive impact on the green innovation of non-state-owned enterprises to varying degrees.The low-carbon city pi
