城市公共服务供给如何促进地区创新?——基于人才与产业集聚效应的检验

How Does the Supply of Urban Public Services Promote Regional Innovation:A Test Based on the Agglomeration Effects of Talents and Industries

基于2011—2020年282个地级及以上城市(市辖区)数据,采用双向固定效应模型检验了差异化的城市公共服务供给对地区创新的影响。研究发现:城市公共服务供给对以专利授权总量来衡量的地区创新水平具有显著的促进作用;机制分析发现,以教育、医疗、交通基础设施为主的城市公共服务主要通过吸引人才与产业集聚促进地区创新;异质性分析表明,这一正向影响在一、二线城市以及财政自给率较高的城市中更为显著,且促进作用与地区内第二、三产业的比重呈正相关关系,尤其第三产业的比重对地区创新的影响更大。上述研究结论为城市通过提升公共服务供给水平以吸引人才与产业集聚,从而促进地区创新提供了现实依据与政策参考。

Based on the panel data of 282 prefecture-level cities(municipal districts)from 2011 to 2020,the study uses a two-way fixed-effect model to examine the impact of differentiated urban public service supply on regional innovation.The results show that the urban public service supply has a significant promoting effect on the regional innovation level measured by the total amount of patent grant.The mechanism analysis indicates that Urban public services,such as education,medical care and transportation infrastructure,promote regional innovation mainly by attracting talents and industrial agglomeration.Heterogeneity analysis reveals that this positive effect is more significant in first-and second-tier cities and cities with higher financial self-sufficiency rate.And its promoting effect is positively correlated with the proportion of secondary and tertiary industries in the region.In particular,the proportion of the tertiary industry has a greater impact on regional innovation.The above conclusions provide practical basis and policy reference for governments to attract talents and industrial agglomeration by improving the level of public service supply,so as to promote regional innovation.
