Research On The Spatial Organization Of Chinese Urban Networks From The Perspective Of Enterprise Networks

Under the background of economic globalization,informationization and industrialization,enterpriseas a new carrier of inter city relation,make the relationship between cities become more and more closely.As an important tool of urban planning and regional policy,urban network has become the focus of urban geography.This paper firstly reviews the other scholars about firm city network research theory and model,establish a compromise network model based on Chinese 2015 Fortune 500 branch information,using the traditional statistical analysis method,network analysis,GIS visual expression method,studied from city network space group the whole industry,from two aspects of the national industry and the typical city group of two regional scale.The conclusions are as follows:(1)Beijing is in the center of the national urban network,and the "Star" network structure is highlighted.The connection from Beijing to Shanghai,Guangzhou,Xi'an and Chengdu is the backbone of China's urban network,which constitutes the basic framework of urban network in china.(2)the overall size of the national urban network is large,the connectivity between cities is low,the nodes are not balanced,the political center is prominent,and the coastal areas and resources are obvious.The concentration of the network space and the regional differences are concomitant.Network development is not perfect,the hierarchy is not clear.(3)the role of the core nodes of the city is strong,the difference between the status of the industry is relatively large and the network is obvious,poor connectivity between the nodes,the central point of differentiation.The main network of the network structure is prominent,the "Star" and "triangle" structure coexist,the "small group" is weak,and the spatial structure has a strong polarization tendency.(4)Beijing Tianjin Hebei Urban Agglomeration of each node of the city has strong connectivity,node development is more balanced,Beijing and Tianjin,"A main center-a sub center" feature is obvious;The centrality and connectivity of each node in the Yangtze River Delta urban agglomeration are similar,Showing the feature of "one super power";The middle reaches of the Yangtze River city group of each node connectivity is weak,showing the network characteristics of a situation of tripartite confrontation";The nodes of Chengdu Chongqing urban agglomeration have strong centripetal direction,low connectivity,and "dual core";In the Pearl River Delta urban agglomeration,the connectivity of each node is high,the centrality is weak,and the network multi center is obvious;The network development of the five major urban agglomerations is closely related to the characteristics of regional development.The structure of "small group" is prominent,and the polarization of the spatial structure is strong,and the single axial connection between the core nodes is still an important link in the network.(5)From the perspective of enterprises,China's urban network has formed different spatial organization patterns in two different industries and urban agglomerations.From different industries,mining,manufacturing,electricity supply and construction can be divided into levels of imperfect multi center mode;financial level for distinct concentric dual core mode;comprehensive level belongs to the distinctive multi center model.From the city perspective,Tianjin city group formed a single nuclear integration model;Yangtze River Delta city group,the Pearl River Delta city group is a multi center integration mode;Chengdu Chongqing city agglomeration mode dual polarization;Yangtze River city group is a multi center polarization mode.
