摘　　要：分析区域物流网络结构能了解物流宏观层面特征。把物流量赋予网络上,构建基于加权网络的区域物流网络。从节点度和强度分布、边的权重差异度、加权集聚性、节点度相关性等对区域物流网络结构进行定量分析。并以湖南省为例,发现其区域内物流节点强度和边差异度大、为同类混合网络等特征,这表明加权网络可以揭示更多区域物流网络的结构特征。It can understand the macro-level characteristics of regional logistics to analyze structure of regional logistics network. The paper,assigning the magnitudes of logistics to network,constitutes regional logistics network based on the weighted network, and makes quantitative analysis to structural characteristics of regional logistics network from four perspectives：node degree and strength,edge weight disparity,weight clustering and node degree correlations.To an example of Hunan province,it finds a few characteristics of logistics node weight disparity been more,same kind mixed network and so on,indicating the weighted network can reveal more structure characteristics of regional logistics network.
