摘　　要：【目的】通过研究微博网络的结构特征,对微博局部世界演化模型进行探究。【方法】以新浪微博全网数据和典型用户拓扑结构为例,引入舆论动力学理论和复杂网络理论进行模型探究。【结果】获取微博用户行为框架,得出划分普通用户和意见领袖的依据,并建立微博局部世界演化模型。【局限】典型用户的选取具有一定的局限性;全网数据的分析具有一定的偏差。【结论】本文建立的微博局部世界演化模型符合真实微博网络的拓扑结构,研究成果有助于了解微博的网络结构。[Objective] Through the study of microblog network＇s features, a local network evolution model of Sina Microblog is developed in this paper. [Methods] With Sina Microblog entire network data and a typical user＇s topological structure, a model is explored based on the theories of public opinion dynamics and complex network. [Results] A framework for microblog users＇ behaviors is obtained, a division basis for ordinary users and opinion leaders is got, and the local network evolution model is developed. [Limitations] In this method, the selection of typical user has its limitation, and the analysis of the entire network data has a certain deviation. [Conclusions] Finally, a conclusion can be obtained that the local network evolution model accord with real microblog network topology. The research work of this paper is helpful to know the microblog network structure well.
