NETWORK STRUCTURE ANALYSIS OF BEIJING-TIANJIN-HEBEI URBAN AGGLOMERATION BASED ON ENTERPRISE DATA:APPLICATION OF REGIONAL SOCIAL NETWORK AND HYPERNETWORK ANALYSIS
In the context of regional cooperation and economic intra-circulation,the real economic linkages of the Beijing-Tianjin-Hebei urban agglomeration are analyzed from the perspective of enterprise data.Based on the social network analysis method,this paper establishes a single-layer network structure,and uses the hypernetwork method to analyze the interaction,cooperation,and influence inside and among layers of the"region-industry"hypernetwork.The results show that:(1)the regional sub-network based on the enterprise measurement shows a large development gap and imbalanced resource allocation,in which Beijing metropolitan area and Shijiazhuang metropolitan area occupy a prominent position,while the radiation of Tianjin is limited to the city area;(2)the industry sub-network based on the capital circulation measurement has a prominent impact on manufacturing,leasing,business services,wholesale and retailing,finance,and scientific research and technology services;(3)major industry categories in the hypernetwork are similar,and the relevant indicators are higher in districts and counties of Beijing,Tianjin,and Shijiazhuang,but more industrial capital outflows go to Beijing and Tianjin rather than Shijiazhuang.These findings are of great value in promoting regional innovation-driven synergistic development.
