Multi-scale urban network connectivity characteristics in the Yangtze River Delta and its impact on high-quality urban development:A perspective on corporate headquarter-branch connections
With the continuous improvement of transportation infrastructure and communica-tion technology,the degree of interaction between cities has significantly increased.Based on panel data of 26 prefecture-level cities in the Yangtze River Delta,this paper investigates the characteristics of the multi-scale urban network and the impact of urban network on high-quality development from the perspective of corporate headquarters-branch connections.The results are as follows:(1)Both the overall network characteristics and the node network connections indi-cate that the urban network at different scales in the Yangtze River Delta exhibits a trend of net-work development.(2)Urban network connections in the Yangtze River Delta exhibit signifi-cant hierarchical characteristics.As the network hierarchy increases,the number of connections decreases,and the levels of participating cities increase,with less constraint imposed by distance and administrative levels.(3)Cities within the Yangtze River Delta can significantly advance high-quality development by integrating into an urban network of different scales,and the im-pact of urban network connections on high-quality development demonstrates both scale hetero-geneity and size heterogeneity.(4)Cities within the Yangtze River Delta primarily achieve high-quality development through three transmission mechanisms:the economic effect,social effect,and innovation effect of the urban network.
