Abstract:

In recent years, it has been an increasing number of studies on the construction of urban networks based on network of firms, in particular, using intra-firm links established by spatial location of headquarters and branches to build urban networks. Different from previous researches, the article builds interurban capital flow network based on the inter-city investment and financing relationship of companies, and finds that:1) The number of interurban capital flows among enterprises increases from 2013 to 2016, and the cover range of investment and financing is becoming wider. Capital is increasingly concentrated in large cities.2) Beijing-Tianjin-Hebei Region, Yangtze River Delta, Pearl River Delta, Chengdu-Chongqing area and Wuhan area stand out in the urban networks shaped by China’s capital flows. The capital flows among Beijing, Shanghai and Shenzhen are the most important connections in the network.3) Compared with the Beijing-Tianjin-Hebei Region and the Pearl River Delta, the internal links of the Yangtze River Delta are more complex and stronger, with a higher level of activity of capital.4) The interurban capital flow is embedded in China's unique institutional environment. The market and the government have influenced the evolution of spatial structure of urban network together.

摘要：

基于企业网络联系构建城市网络研究是近年来的研究热点。以往研究多运用企业总部与分支机构的空间位置关系建立企业内部联系，以构建城市网络，缺少从企业间实际联系层面对城市网络的研究。本文利用企业间跨城市投融资关系建立城市联系并探究其驱动机制，为中国城市网络研究提供了新的思路。研究发现：①2013—2016年全国企业间跨城市资本流动数量不断增加，全国范围内投融资覆盖面越来越广，资本越发集中于大城市。②中国资本流动城市网络基本形成了以京津冀、长三角、珠三角、成渝地区以及武汉等城市为重要节点相互联系的空间结构，京深、京沪和深沪是网络中最重要的城市联系对。③长三角城市群内部联系最为密切，形成的城市网络最为复杂，资本活跃程度高；京津冀、珠三角城市群内部城市间联系相对较弱，“核心-边缘”结构分化较为严重。④中国城市网络嵌入在独特的制度环境中，市场和政府作用共同导致了城市网络空间结构演化。
