基于快递企业总-分机构的中国城市网络空间结构

Spatial structure of urban network in China based on the headquarters and branches of express enterprises

从流空间的角度入手,通过采集跨省市经营的快递企业的总-分机构所在的地级城市,进行300×300矩阵构架,对中国城市网络空间结构进行分析,揭示不同等级城市间在流空间作用下的特征。研究结果表明:1)全国范围内京广沪城市联系流呈现三角形结构;2)上海-长春和上海-哈尔滨这两组城市联系表现得较为明显;呼和浩特-北京和包头-北京这两组城市联系有待提升,这4个节点城市承担着除省会城市外与京津冀、长三角城市群核心城市联系的重要功能补充;3)郑州、武汉、长沙等中部城市与其他城市联系程度较为明显,但在区域内部城市联系网络不突出,集聚程度低;4)成都与京津冀、长三角、珠三角城市群核心城市联系较为紧密。

In this work we start from the perspective of the space of flows by collecting interprovincial headquarters and branches of express enterprises and structure 300 ~ 300 matrix architecture. The spatial structure of the urban network is analyzed, and different characters as the effects of the space of the flow among cities at different levels are revealed. The results are showed as follows. 1 ） Nationwide Beijing-Guangzhou - Shanghai city flow presents a triangular structure. 2） The linkages between Shanghai - Changchun and Shanghai-Harbin are obvious. The connections between Hohhot-Beijing and Baotou-Beijing should Wuhan, and Changsha are obvious compared be improved. 3 ） The central cities of Zhengzhou, other cities, but in the contact area of the cities the network is not prominent and the degree of concentration is low. 4） The urban linkages between Chengdu and Beijing-Tianjin and between Chengdu and the Yangtze River Delta city group core are close,
