Research on the evolution characteristics and influencing factors of urban network structure in Shandong Province based on the connection of listed enterprises
Based on the data of headquarters and branches of listed enterprises from 2010 to 2020,this paper establishes the related network in Shandong Province,and adopts the social net-work analysis method to analyze the temporal and spatial evolution characteristics and the main influencing factors from both internal and external perspectives.The results show that:(1)The internal association network presents the structural characteristics of polycentric and networked development,which has evolved from the single center structure with Jinan as the core to the double core structure of Jinan and Qingdao.In addition,the importance of Yantai begins to ap-pear as the third pole,but the network location of marginal cities presents"Matthew effect".(2)The external connection network shows that Shandong Province has established long-distance and large-scale jumping links across regions.Shandong Province has relatively strong cohesion to the three major urban agglomerations of Beijing Tianjin Hebei,the Yangtze River Delta and the Pearl River Delta,but relatively strong radiation to the urban agglomerations in the Yellow River Basin.The urban connection network has formed a dual core development model of Qing-dao and Jinan.The external connection ability of Yantai has been significantly improved,and its importance has begun to become prominent.(3)Economic level,innovation ability,administra-tive relationship and geographical proximity have a significant impact on the formation of the current inter-city and inter-city association network structure,but the administrative relationship is the main influence in the province,and transportation has become the key to the evolution of the inter provincial urban network structure.
