摘　　要：首先根据东莞市2006～2009年物流企业数据,构建了物流企业布尔竞争关系网络模型和加权竞争关系网络模型。然后,用各种静态几何量分析了各年度网络模型的结构属性,并探讨了网络演化的动力机制和经济学背景。通过分析发现,各年度网络的节点度服从幂律尾部分布,直角坐标系下累计节点入度权近似于直线分布,节点出度权服从无标度分布。网络具有小世界特性,并且具有增长性和偏好性。First, the Boolean competitive relationship network and the weighted competitive relationship network model among the logistics enterprises are constructed according to logistics enterprises data from the year 2006 to 2009 in Dong guan. Then, the authors analyze network structure properties each year with different static indexes, and discuss the dynamic mechanism of the network structure evolution and the economic background. The results show that the node degree of the annual network follows the two-stage power-law distribution, the cumulative node in-strength follows straight line distribution in the rectangular coordinate system and the node out-strength follows scale-free distribution. The network shows characteristic of clear small-world property, growth and preference.
