碳交易和创新型试点政策的绿色创新效应研究
Research on the Green Innovation Effects of Carbon Trading and Innovative Pilot Policies
摘要
Abstract
Using panel data from Chinese prefecture-level cities spanning 2005-2022 and employing a multi-period difference-in-differences(DID)model,this study examines whether urban green innovation levels are associated with carbon emissions trading and innovative city pilot policies.The results show that:(1)The implementation of both policies is exerting a significant positive im-pact on urban green innovation capacity.Compared to a single pilot policy,the dual pilot policy demonstrates more pronounced green innovation effects.Furthermore,the green innovation effects achieved by cities that first become innovation-oriented cities and then car-bon trading cities exhibit greater sustainability than those achieved by cities that first become carbon trading pilot cities and then innova-tion-oriented cities.(2)Mechanism tests indicate that the dual-pilot cities can enhance their green innovation levels by increasing gov-ernment support,upgrading industrial structures,and raising human capital levels.(3)Heterogeneity analysis reveals that urban loca-tion and resource types significantly influence the policy effects of the dual pilot initiative,with eastern and western regions and non-re-source-based cities exhibiting notably positive green innovation effects.Policy recommendations are proposed based on these findings to enhance policy effectiveness and expand the pathways for urban green innovation development.关键词
