中国城市体系跨境网络结构特征——基于世界500强企业母子关系分析

为了认识中国城市体系跨境网络结构特征,以世界500强企业的母子企业间的内在关系视作城市之间的联系证据,建构中国境内城市与境外城市之2-模网络,从总体网络、内源网络和外源网络3个维度进行分析。结果表明:总体网络区域分布较广而差异大,网络要素总体上呈现位序-规模分布,又不同程度偏离"理想值";外源网络相对内源网络发育,并在城市构成上形成部分差异;外源网络度数中心度、核心-边缘分化特点显著,同时境内的上海、北京、广州、苏州等之间,境外的东京、首尔、新加坡、纽约等之间呈现显著的联系共享特点。

Structural Characteristics of Cross Border Network in Chinese Urban System:Based on the Headquarter-Affiliate Relationship of World 500 Top Enterprises

As an attempt to investigate the structural characteristics of cross border network in Chinese urban system, it was analyzed the structural property of the 2-mode network which composed of cities connected by the headquarter-affiliate relationship of the world’ s top 500 enterprises. The results are as follows:Firstly, network dis-tributes broadly and differently by regions. Secondly, network elements show rank-size distribution on the whole, and show varying degrees of deviation from “ideal value”. Thirdly, endogenous network and exogenous network forms some differences in composition of cities. Forthly, exogenous network has large scale than endogenous network, and forms a certain structural features within it. Fifthly, in exogenous network, structural features of degree centrality and the core-periphery is revealed significantly, and cities among Shanghai, Beijing, Guangzhou, Suzhou, etc., and a-mong the outside Tokyo, Seoul, Singapore, New York, etc., showed a significant link shared characteristics.
