摘　　要：绿色技术创新已成为中国实现“双碳”目标的重要方案,如何促进绿色技术创新则成为当前城市实现经济绿色发展的迫切任务。已有相关研究大多着眼于生产性服务业集聚与技术创新之间的关系,但将绿色技术创新作为切入点的研究较少,关注生产性服务业集聚与绿色技术创新空间关联的研究则更为缺乏。为此,在阐述生产性服务业集聚对绿色技术创新的作用机制基础上,以中国2008—2019年266个城市为样本,采用空间杜宾模型实证检验生产性服务业集聚对绿色技术创新的空间效应及作用机制,并考察人力资本积累对二者关系的调节效应。研究发现:生产性服务业集聚能够显著促进城市绿色技术创新,经过一系列稳健性检验后,该结论依然成立。作用机制分析结果显示,生产性服务业多样化集聚有助于改善本地及邻地绿色技术创新,而专业化集聚仅促进了本地绿色技术创新。与此同时,城市人力资本积累水平越高,越有利于提升生产性服务业集聚的绿色技术创新效应。异质性分析发现,人力资本积累与生产性服务业集聚对绿色技术创新的综合效应在特大型及以上城市和高端生产性服务业的表现更明显。最后,基于理论和实证的研究结论提出应重视生产性服务业集聚的质量、不断强化人力资本积累、加快区域绿色技术创新收敛的政策建议。研究结论为推动绿色技术创新发展提供了新思路,也为推动城市经济绿色转型提供了经验借鉴和政策启示。Green technology innovation has become an important plan for China to achieve carbon peak and carbon neutrality goals, and how to promote green technology innovation has become an urgent task for the green development of urban economy at present.Most of the existing studies focus on the relationship between producer services agglomeration and technological innovation, but few studies take green technological innovation as a starting point, and even fewer studies focus on the spatial correlation between producer services agglomeration and green technological innovation.On that account, 266 cities in China from 2008 to 2019 are selected as samples and the spatial Durbin model is used to empirically study the spatial effects of producer services agglomeration on green technology innovation.The research results are shown as follow:(1) It is found that producer services agglomeration can significantly facilitate urban green technology innovation, and this conclusion still holds after a series of robustness tests.(2) Analysis of the mechanism proves that diversified agglomeration of producer services helps to improve local and neighboring green technology innovation, while specialized agglomeration of producer services only promotes local green technology innovation.At the same time, human capital accumulation can effectively improve the green technology innovation effect of producer services agglomeration.(3) Heterogeneity analysis shows that the comprehensive effect of human capital accumulation and producer services agglomeration on green technology innovation is more obvious in mega-cities and high-end producer services.Based on the above research conclusions, in order to accelerate the agglomeration of producer services and promote urban green technology innovation, the following policy recommendations are put forward:(1) Urban development should focus on the agglomeration quality of producer services and enhance the supporting role of industrial agglomeration in green economic development.On the one hand, urban d
