| The new generation of intelligent technology clusters has pushed the economy and society into a "service-oriented economy" society with smart services as the core.Smart services capabilities based on artificial intelligence have become a new driving force for cities to achieve highquality development.At the same time,the new generation of information technology has broken the limitations of physical space and promotes the transformation of industrial agglomeration from geographical agglomeration model to virtual agglomeration model centered on real-time data and information exchange,forming the "dual industrial agglomeration" model in which "virtual agglomeration" and "geographical agglomeration" coexist.However,the innovation ability and development level among regions in China are not balanced.The construction of urban agglomeration and metropolitan area faces many bottlenecks such as investment,technology and talents,which seriously restrict the coordinated development of regions.The smart services regard intelligent products as the boundary objects of the network,and interconnect the resources of service system participants through the network,promoting the crossboundary transfer of information and knowledge,and the interaction of participants and the co-creation of value.Therefore,as an important manifestation of the integration of advanced technology and the real economy,the perception,connectivity,and spillover of smart services are important ways to obtain new regional competitive advantages and solve the problems of regional innovation and development in China.Based on the above theoretical and practical background,this study explored the theoretical basis,internal logic and construction path of"improving quality and efficiency" of smart services to promote regional innovation.Specifically,this paper includes three sub studies.First,by constructing a comprehensive indicator system for the development of regional smart services,this paper measures the smart services at the city level,and empirically verify that Chinese cities can acquire new regional competitive advantages through smart services and then realize the feasibility of regional innovation to improve quality and efficiency.Second,based on the dual perspective of industrial agglomeration,this paper reveals the differentiated mechanism of China’s urban smart services to promote regional innovation and development from the perspectives of physical agglomeration and virtual agglomeration,and depicts the dual path of smart services enabling regional innovation in the digital era.Third,based on the perspective of spatial spillover,this paper explores the boundary conditions and the spatial spillover effect of smart service on regional innovation performance,and expands the context and connotation of smart service enabling regional innovation to improve quality and efficiency.The main findings of this study are as follows:(1)Smart services have a significant positive impact on regional innovation performance.(2)Affected by network externalities,smart services have a U-shaped nonlinear effect on regional innovation quantity,while a nonlinear effect on regional innovation quality which decreases first and then increases by marginal effect.(3)The influence of smart services on regional innovation performance is heterogeneous among different regions.(4)The dual industrial agglomeration,physical agglomeration and virtual agglomeration,plays a mediating role in the relationship between regional smart services and regional innovation performance.(5)The smart services have a spatial spillover effect on the regional innovation performance of neighboring regions. |
