摘要:

全球化、信息化与快速城市化深刻影响了中国的城市体系,多区位企业组织所形成的城市网络正处于日益复杂的空间嬗变过程。基于2010年企业名录的总部—分支机构型关联数据,研究构建了330×330的地级以上城市网络连接关系,并运用复杂网络分析工具来探索中国城市网络的空间组织特征。研究发现:① 中国的城市网络联系呈现以“北京—上海—广深—成都”为核心的菱形空间结构,不同等级的网络流强度具有显著的空间异质性,城市网络的空间组织是一个择优性和地理邻近性复杂作用的过程;② 中国城市网络正处于一个简单随机向复杂有序结构的转化期,整体大尺度的网络结构还有待形成;③ 中国城市网络整体表现出明显的小世界网络效应;④ 中国城市的二值点度网络为明显的异配性连接特征,而加权强度网络连接则一定程度上表现出“富人圈”的现象;⑤ 中国城市网络的层级性并不明显,城市网络的点度和强度的关系呈非线性增加特征。

Abstract:

Fuelled by globalization, informatization and rapid urbanization, the Chinese urban system has witnessed dramatic changes in the past four decades, which shows a combined changing characteristic in both expanded geographical scope and intensified intercity connections. This paper investigates an integrated network-based approaches and spatial analysis to explore the spatial organization process and the basic regularity of Chinese intercity networks. More specifically, this study examines how 330 Chinese cities are connected through 108,570 ownership linkages of 307,915 local corporations for the year 2010. Major findings include: (1) the backbone of the Chinese intercity corporate network is diamond-shaped and anchored by four major metropolitan areas (Beijing in the North; Shanghai, East; Guangzhou-Shenzhen, South; Chengdu, West), intercity network strengths reveal a significant spatial heterogeneity; (2) urban network organization is a complicated process that involve both preferential attachment and geographic proximity interactions; (3) the overall structure of the intercity corporate networks undergo a transition process that from a simple random period to a complex but orderly one and also features small-world network properties; (4) city degree distribution of Chinese intercity networks is characterized by weak assortativity and rich-club effects; and (5) a combination interpretation of clustering coefficient and degree distribution identifies hierarchical and regional tendencies.
