基于企业数据的京津冀城市群网络结构解析——区域性社会网络和超网络分析的应用

NETWORK STRUCTURE ANALYSIS OF BEIJING-TIANJIN-HEBEI URBAN AGGLOMERATION BASED ON ENTERPRISE DATA:APPLICATION OF REGIONAL SOCIAL NETWORK AND HYPERNETWORK ANALYSIS

在区域协同合作、经济内循环的背景下,从企业数据出发对京津冀城市群真实的经济关联进行解析。基于社会网络分析方法刻画单层网络结构,并将超网络方法引入分析“地区-行业”网络的层内和层间交互、合作和影响情况。结果表明:(1)基于企业组织测度的地区子网络区域内发展差距大、资源配置失衡,北京都市圈和石家庄都市圈地位突出,天津的辐射能力局限于市域范围内;(2)基于资本流通测度的行业子网络中,制造业、租赁和商务服务业、批发和零售业、金融业、科学研究和技术服务业影响突出;(3)超网络中的重要行业门类相似,北京、天津和石家庄各区县的相关指标均较高,但行业流出的资本更多地去往北京、天津而非石家庄。这些发现对于促进区域创新驱动协同发展具有重要价值。

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.
