SPATIAL STRUCTURE OF CHINESE INTERCITY NETWORK BASED ON THE DATA OF LISTED COMPANIES
Based on the network data of A-share listed companies headquarters and its subsidiaries,this paper constructs the urban network covering 286 prefecture-level cities in China and using network analysis tool like GIS and Ucinet.After a comprehensive measuring,this article reveals the complexity of urban network space structure from the perspective of the enterprise organization.The result shows that:The location distribution of headquarters of listed companies in China presents a fairly obvious spatial agglomeration trend toward Yangtze River Delta Region,Pearl River Delta Region,Beijing-Tianjin-Hebei Region,and Shandong Peninsula urban agglomeration along the eastern coastal region of China,the urban agglomeration in the mid-stream region of Yangtze River Delta Region,and Chengdu-Chongqing Economic Area in the western region of China;all network nodes are graded according to the total amount of communications,so Beijing,Shanghai and Shenzhen are taken as the national network centers;it shows an obvious spatial gradient pattern that the east is dense and strong while the west is sparse and weak in the city network connection.And the high-value connection flow forms a diamond structure with Beijing-Tianjin,Shanghai,Shenzhen-Guangzhou,and Chengdu-Chongqing as the four vertices;different levels of network connection show different spatial heterogeneity.The spatial organizations of network connection are mainly the central radiation from the core node and the adjacent link in local areas;the entire network shows the characteristic of scale-free network,and the "small world" network feature is presented.
