Spatial-temporal evolution and influencing factors analysis of digital technology innovation in Chinese cities
Under the new round of technological revolution and industrial transformation,it is crucial to vigor-ously develop digital technology.This paper defines digital technologies using patent data and employs them as a measure of urban digital technology innovation.Spatial statistical and econometric methods are used to re-veal the temporal evolution,spatial evolution,and influencing factors of digital technology innovation in Chinese cities.The results are as following:1)The scale of digital technology innovation in China presents a monotonically increasing trend driven by multiple factors such as demand and policies,with the innovation scale of 7 subdivided fields maintaining a relatively stable hierarchical pattern.2)There are significant spatial differences in digital technology innovation across Chinese cities.Its evolution exhibits a notable trend of ag-glomeration and diffusion coexistence,forming a digital technology innovation pattern with the Beijing-Tianjin-Hebei(BTH),the Yangtze River Delta(YRD),the Pearl River Delta(PRD)urban agglomerations as the core drivers,provincial capitals and sub-provincial cities as multi-point supporters.The spatial evolution of innova-tion in the 7 digital technology fields shows a similar process of diffusion from core cities to peripheral cities.The outputs of all types of digital technologies are highly concentrated in leading cities like Beijing,Shanghai,and Shenzhen,but the main city compositions for different types of digital technologies differ slightly.Some cities with overall middle-to-high rankings demonstrate relative comparative advantages in specific digital tech-nology fields.3)The influencing factors of digital technology innovation in Chinese cities exhibit significant spatial spillover characteristics.Knowledge bases and technology introduction are important factors promoting local digital technology innovation.However,the role of institutional factors in driving local digital techno-logy innovation remains to be highlighted.Neighboring regions'explanatory variables usually have a reverse impact on local digital technology innovation due to the suction effect or a unidirectional impact due to the spillover effect.The heterogeneity analysis shows that the influencing factors for the 7 digital technologies ex-hibit both similarities and heterogeneities.
