数字技术对城市创新能力的影响研究OA

As the primary form of new-type urbanization,urban agglomerations serve as vital platforms supporting China's economic growth.Currently,digital technology serves as a new engine driving high-quality regional economic development and innovation capacity enhancement,and should consequently play a significant role in advancing innovation within urban agglomerations and their constituent cities.Against this backdrop,it is imperative to explore ways to more effectively leverage the inclusive benefits of digital technology to enhance the innovation capacity of urban agglomerations. By manually compiling relevant indicators on the innovation capacity of urban agglomerations from the Chinese Social Sciences Citation Index(CSSCI)journal articles and conducting frequency analysis,while drawing on renowned Chinese and international research reports,this paper innovatively constructs an indicator system for the innovation capacity of cities within urban agglomerations.This system encompasses 25 indicators across five dimensions:innovation resources,knowledge creation,innovation performance,innovation environment,and innovation collaboration.Using panel data from 196 cities across 19 major urban agglomerations in China from 2008 to 2021,this paper employs a panel fixed-effects model to empirically examine the impact of digital technology on the innovation capacity of cities within urban agglomerations and the underlying mechanisms. The main findings are as follows.Benchmark regression indicates that digital technology can enhance the innovation capacity of cities within urban agglomerations,and this conclusion holds under a series of robustness tests.Mechanism tests reveal that digital technology enhances innovation capacity through innovation capital aggregation,industrial structure upgrading,and increased entrepreneurial activity.Heterogeneity analysis indicates that digital technology exerts a more pronounced effect on cities within urban agglomerations characterized by higher development stages,smaller scales,advanced innovation infrastructure,and polycentric structures. The potential contributions of this paper are threefold.First,by focusing on urban agglomerations,this paper expands research on the relationship between digital technology and innovation capacity.Second,it constructs a more comprehensive,scientific,and comparable indicator system for the innovation capacity of urban agglomerations,providing a reusable framework for subsequent research.Third,it deepens the analysis of the mechanisms by which digital technology affects urban innovation capacity,as well as the heterogeneity across different types of urban agglomerations.This paper enhances understanding of the intrinsic patterns in the impact of digital technology on the innovation capacity of cities within urban agglomerations,providing empirical evidence and policy insights to advance the development of digital technology,integrated urban agglomeration growth,and innovation capacity enhancement in China.
