摘要
基于中国2001~2016年的城市数据和2012年首批智慧城市试点的准自然试验,利用双重差分法从影响路径、动态效应、异质性三个维度研究了智慧城市建设对城市创新能力的影响。研究结果表明:智慧城市建设显著推动了城市创新能力的提升,并主要通过信息基础设施建设和数据赋能两种途径发挥作用;智慧城市建设的城市创新效应在当期不能显现出来,但随着时间的推移创新效应逐渐增强;在人力资本水平高、科技财政支出强度与人口规模大的城市,智慧城市建设对城市创新能力的提升效应更显著。
Based on the Chinese city data from 2001 to 2016 and quasi-natural test of smart city pilot in 2012, this paper uses the double difference method to study the impact of smart city construction on urban innovation capability from the three dimensions of influence path, dynamic effect and heterogeneity.The research results show that the construction of smart cities significantly promotes the improvement of urban innovation capabilities, and mainly through the two channels of information infrastructure construction and data empowerment.The urban innovation effect of smart city construction cannot be revealed in the current period, but the innovation effect gradually increases with the passage of time.In cities with high level of human capital, strong fiscal expenditure, and large population, the impact of smart city construction on urban innovation capacity is more significant.
