基于快递运单数据的城市群空间联系结构分析

Analysis of Spatial Contact Structure of Urban Agglomeration Based on Express Waybill Data

城市群的空间联系结构是城际经济联系的重要表现,也是城市群规划的基础。快递运营网络是城际商务和生活联系的重要组成部分。本文从快递企业网络入手,基于快递运单数据,以长三角为例,分析快递网络的流量特征,以此为基础,研究城市群的空间联系结构。研究发现:长三角地区快递网络流量分布不均衡,城市群空间联系结构具有很强的等级特征:上海市为第一层级,杭州市、苏州市为第二层级,其余城市为第三层级;上海市、杭州市、苏州市、金华市之间的联系很紧密,城市群效应明显;上海市、金华市是主要的快递输出城市。

The spatial connection structure of urban agglomerations is an important manifestation of intercity economic relations and the basis of urban agglomeration planning. The express operation network is an important part of the inter-city business and life connection. This article starts from the express delivery company network, and analyzes the traffic characteristics of the express delivery network based on the express waybill data, taking the Yangtze River Delta as an example. Based on this, the spatial connection structure of urban agglomerations is studied to provide reference for urban agglomeration transportation planning.The main conclusions are: the distribution of express network traffic in the Yangtze River Delta region is very uneven, and the spatial connection structure of urban agglomerations has strong hierarchical characteristics: Shanghai is the first level, Hangzhou and Suzhou are the second level, and the remaining cities are the third level. The links between Shanghai, Hangzhou, Suzhou and Jinhua are very close, and the urban agglomeration effect is obvious. Shanghai and Jinhua are the major express delivery cities.
