Research on the Spatiotemporal Evolution of Yangtze River Delta Smart City Cluster Network Based on Enterprises Investment Links:A Case Study of New Infrastructure Enterprises
Smart city clusters are becoming a future development trend,with investments from new infrastructure enterprises driving the formation of smart city cluster networks.This paper takes the Yangtze River Delta city cluster as the research object and uses investment data from new infrastructure enterprises to explore the evolutionary characteristics of the Yangtze River Delta smart city cluster network from 2016 to 2021 through chain network models and social network analysis methods.The study found that:① In terms of the temporal and spatial evolution of new infrastructure enterprise investment behavior,it is significantly influenced by policies,with investment scales showing wave-like growth and the spatial scope continuously expanding.However,investment locations are relatively singular,and cities with strong cross-regional connections and high connectivity are mostly clustered in"gateway"cities.② Regarding the evolution of the Yangtze River Delta smart city cluster network based on investment connections,the trend towards networkization is continuously strengthening,and the hierarchical structure is gradually becoming more apparent.The pattern has evolved from a dual-core radiation network to a multi-core network structure,with the spatial form of metropolitan areas beginning to emerge.The status and roles of node cities within the network are diverse.③ Compared to traditional city cluster networks,the smart city cluster network is in an early development stage,with network density needing improvement,the radiation driving effect of core cities needing enhancement,and the"bridge"role of secondary core cities not being significant enough.The network structure is more greatly influenced by the degree of integration of information infrastructure.
