摘　　要：自由贸易试验区建设以绿色为底色,以创新为驱动,是促进经济高质量发展的催化剂。选取2006—2022年中国284个地级市的面板数据,基于创新价值链视角研究自由贸易试验区建设对城市绿色创新效率以及子阶段效率的直接影响、影响机制和影响的空间溢出效应,得出以下研究结论:(1)自由贸易试验区建设能够提高城市绿色创新效率以及绿色科技研发和绿色成果转化两个子阶段效率,这一结论经过双重机器学习再检验和内生性分析等一系列检验依旧稳健;(2)这一高水平制度性开放举措在沿海城市、高营商环境城市和低环境规制城市的政策效应更显著;(3)提高城市创业活跃度、促进创新人才流动和加强战略新兴产业集聚是自由贸易试验区建设提高城市绿色创新效率以及子阶段效率的作用机制;(4)自由贸易试验区建设对周围城市绿色创新效率和绿色科技研发效率产生显著的正向影响,且正向空间溢出的衰减边界分别为350千米和200千米,而自由贸易试验区建设对周围城市绿色成果转化效率的影响不显著。在此基础上,为中国推进自由贸易试验区战略分层次、多维度和分阶段地提升城市绿色创新效率提供政策建议。The construction of pilot free trade zones(PFTZ)is green-based and innovation-driven,and promotes high-quality economic development.Based on the panel data of 284 prefecture-level cities in China from 2006 to 2022,this study investigates the direct effect,mechanism and spatial spillover effect of the construction of PFTZ on the urban green innovation efficiency as well as the efficiency of the sub-stages from the perspective of the innovation value chain,and draws the following conclusions:(1)The construction of PFTZ can improve the urban green innovation efficiency as well as green technology research and development efficiency and green achievement transformation efficiency,which remains robust after double machine learning retest and endogenous analysis;(2)The policy effect is more significant in the coastal cities,cities with high business environment and cities with low environmental regulation intensity;(3)Increasing entrepreneurial activity,promoting the flow of innovative talents and strengthening the agglomeration of strategic emerging industries are the mechanisms by which the construction of PFTZ can enhances green innovation efficiency and sub-stage efficiency;(4)The construction of PFTZ has a positive impact on green innovation efficiency and green technology research and development efficiency of the surrounding cities,and the attenuation boundaries of the positive spatial spillover are 350 km and 200 km,respectively,while the construction of PFTZ does not have a significant impact on green technology transfer efficiency of the surrounding cities.The study provides policy suggestions for increasing the urban green innovation efficiency in a hierarchical,multi-dimensional and phased manner by the construction of PFTZ.
