摘 要：市场经济充分发展，行业竞争加剧，物流成本是竞争的焦点之一。为了更好提高物流配送效率、降低物流成本，对配送网络及节点布局进行研究尤为重要。本文选取非常态垄断快消品这一特殊商品的物流配送网络开展研究，基于复杂网络理论构建了1065´1065的邻接矩阵，对其配送网络及网络特性进行分析，并构筑配送网络的拓扑模型，以揭示该复杂网络的点、边、度与度分布、网络直径、平均路径长度、聚类系数等整体特性，通过点度中心性、接近中心性、中介中心性等指标探寻网络中的重要节点。以重庆卷烟配送网络为例对该方法进行了验证，研究结果可以指导对关键节点进行重点保护，以避免或减少网络遭遇破坏时的损失；有助于其物流网络节点的布局及优化，降低物流成本，与市场竞争接轨。

Abstract: With the development of market economy and the increasing competition in the industry, logistics cost is one of the focuses for competition. In order to improve the efficiency of logistics distribution and reduce the logistics cost, it is very important to study the distribution network and the layout of nodes. We select the logistics distribution network of non-conventional Monopoly FMCG, based on the complex network theory, construct the adjacency matrix of 1065´1065 and the topology model, study its distribution network and complex network characteristics, in order to reveal the complex network Degree, Diameter, Averagepath length, Clustering coefficient and so on. And then, put forward to evaluate the node importance for three indicators in Degree centrality, Closeness centrality and Betweeness centrality. Taking the Cigarette distribution network as an example, verify the method. The research results can guide the protection of key nodes, in order to avoid or reduce the losses suffered damage network; and contribute to the layout and optimization of its logistics network nodes, reducing logistics costs, helping to participate in market competition.
