中国物流运营网络中的城市节点层级分析

Study on Hierarchy of City Nodes in Logistics Operation Network in China

根据5A级物流企业在我国各城市业务网点布局数据,建立了以城市为节点的物流运营网络,并利用复杂网络4个中心性指标,从联系广度和联系强度两个维度构建了城市对外物流联系能力评价体系。依据每个城市的4项指标值,用聚类分析的方法将城市节点分级,并计算了4项指标对分级的影响力,在此基础上提出基于区块划分和圈层划分的节点城市层级分析模型,据此揭示城市的发展方向和路径。最后,结合不同地区城市节点层级分布形态,分析了对各地区城市节点层级结构进行合理化调整的方向,并指出了各地区的潜力城市。

In this paper, a logistic operation network is constructed with cities being nodes, using network layout data of 5A logistics enterprises. On the basis of four centrality indices in complex network theory, an evaluation system for urban external association ability is established from two aspects of association extent and association strength. The centrality indices are then utilized to classify the city nodes by means of Clustering Analysis, and its influence to the classification is calculated as well. Sequentially, this paper proposes an analytical method on city-node hierarchy division, which involves block partition and layer partition, and illustrate the development directions and paths of cities. Finally, based on specific distribution patterns of city nodes in different areas, a rational adjustment direction is put forward on the hierarchy structure of various city nodes, and accordingly the most promising cities.
