摘　　要：针对社会通信网络中心性度量问题,在CDMA手机通话数据的基础上构建社会通信网络,引入新的局域影响力度量指标——拓扑势,结合度、介数和接近度等经典参数,对社会通信网络局域中心性进行实证分析.发现社会通信网络节点度、介数和拓扑势的累积分布均服从漂移幂律分布,接近度为正态分布;另外,随着用户局域影响范围σ的增大,其局域中心性大小与其联系人数目和连接中介能力的正相关性逐渐减弱,而与其在网络中拓扑位置的正相关性增强.Aiming at the problem of the local centrality measurement of social communication network,a social communication network was constructed with CDMA mobile call recordings,and topology potential,a new measurement of local influence in networks,was used to analyze empirically the local centrality of social communication network together with degree,betweenness and closeness.Experimental results show that the cumulative distributions for degree,betweenness and topology potential of nodes follow shifted power law distribution,closeness follows normal distribution,and the larger the scope of users＇ local influences σ in the network is,the weaker the positive correlations of their local centrality with the number of their contacts and connection intermediary are.On the contrary,the positive correlation of local centrality with topology position in the network become larger with the increase of σ.
