摘　　要：在综合运输体系下如何建立一个合理的快捷货运服务网络是政府部门和货物运营公司共同关心的问题。文章阐述了影响快捷货运服务网络结构的主要因素,并运用系统结构模型进行了快捷货运服务网络结构影响因素分析:首先构造多个影响因素的有向连接图,建立了邻接矩阵,然后基于推移率定律运算获得可达性矩阵,并最终建立了快捷货运服务网络结构影响因素的递阶层次结构,从而为识别快捷货运服务网络结构影响因素的主次、关联关系奠定了基础。It described the main influencing factors of service network structure in express freight, and analyzed the factors by using the system structure model. The process of the analysis included three steps. First of all, it built a connection graph including various factors and created the adjacency matrix. Then accessibility matrix can be calculated through transition probability law. Finally, it estabhshed the progressiveness hierarchy about the main factors of service network structure, and so these results can be considered as the foundation for discerning the importance and interrelationship of those main factors.

关 键 词：快捷货运 服务网络结构 可达性矩阵 多层递阶结构
