摘要
基于2015年世界财富500强中的102家中国企业数据,根据企业组织特征构建了反映企业—城市间关联的折衷网络模型,借助网络分析等多种方法分析了中国地级城市间和典型城市群之间的网络联系。研究发现:①城市网络总体连通性较差、向心集中性强,发育不够完备;城市网络连接具有明显的行政中心指向、沿海指向和资源指向;网络节点城市对外经济依赖度高,网络结构扁平特征明显。城市群网络存在权力分散、地位分化和外部联系依赖特征。②城市网络中省域、城市群和俱乐部边界效应明显,区域内外的中心城市规模和数量对省域行政区经济、城市群经济和俱乐部经济的发展产生影响。③城市在多尺度网络中的功能分化明显,大城市和区域型中心城市比中小城市拥有更加完备和均衡的功能体系。沿海三大城市群的辐射带动作用明显,其他城市群的优势功能有待突出。④城市(群)跨尺度区域功能互动效应显著,城市(群)的自我经济集聚能力与城市(群)的对外辐射带动功能之间存在密切的正向关系。研究为城市网络模型拓展及理解中国城市网络空间联系特征提供了支撑。
Based on the data of Chinese enterprises that entered the Fortune 500 list in 2015,this paper uses the eclectic model to construct the inter-city association network.Using the network analysis method,the spatial connection characteristics of 311 inter-city networks at prefecture level and above and 20 urban agglomerations networks in China are examined respectively.The research found that:(1)The overall connectivity of urban network is poor,the centripetal concentration is strong,and the network is not complete.The urban network connection shows a strong tendency of political center cities directivity,coastal cities directivity as well as resource-based cities directivity.The external economic dependence of each node city in the urban network is high,and the urban network structure has obvious flattening characteristics.The network of urban agglomerations is characterized by decentralization of power,differentiation of status and dependence on external connections.(2)The boundary effect of provinces,urban agglomerations and urban agglomerations clubs in the urban network is significant.The network evolution process is influenced by the provincial administrative district economy,the urban agglomerations economy and the urban agglomerations club economy.The size and number of central cities in the region and its surrounding areas have an impact on the provincial administrative district economy,the city agglomerations economy and the urban agglomerations club economy.(3)The function of cities is obviously divided in a multi-scale network.The large cities and regional central cities have a complete and more balanced function system than the small and medium-sized cities do.The radiation effect of three major urban agglomerations in coastal China is significant,while the dominant function of other urban agglomerations needs to be strengthened.(4)The crossscale regional functional interaction effect of cities(clusters)is significant.The radiationdriven function of cities(clusters)is positively related to their self-agglomeration capabilities.This study provides support for the understanding of urban network model expansion and the spatial relation of urban network in China.
