基于复杂网络的长三角城市物流网络演化分析

Analysis of Logistics Network Evolution in Yangtze River Delta Cities Based on Complex Network

基于改进的复杂网络BBV演化模型,分析长三角全域41个城市物流网络演化规律,描述长三角各城市在城市经济发展水平、物流能力、物流需求等方面的协同演化、相互迭代过程。结果表明:长三角城市物流网络具备小世界性,各城市之间联系紧密,枢纽城市作用显著;上海、南京、宁波等8个城市在长三角城市物流网络中的地位重大,其中上海以极大优势超出其他城市,充分体现出上海在长三角的领导地位;长三角城市物流网络是由多中心节点和多外围节点共同组成的层次结构,轴辐式物流网络结构特征明显。

In this paper, based on the improved BBV evolution model of complex network, this paper analyzed the evolution pattern of the logistics network in 41 cities in the Yangtze River Delta, and described the co-evolution and mutual iteration process of the cities in terms of economic development level, logistics capacity, and logistics demand, etc. The result showed that the logistics network of the cities in the Yangtze River Delta had the small-world nature, the cities were closely connected, and the hub cities had more significant role to play;eight cities, including Shanghai, Nanjing, and Ningbo were more prominently positioned in the urban logistics network of the Yangtze River Delta,among which Shanghai was leading by a large margin, fully reflecting the dominating position of the city in the Yangtze River Delta;and the the urban logistics network in the Yangtze River Delta is a hierarchical structure composed of multi-center nodes and multi-peripheral nodes, and has obvious hub-and-spoke characteristics.
