摘　　要：社团结构是复杂网络除小世界和无标度特性外的又一重要性质。建立具有社团结构的有界信任舆论涌现模型,采用Multi-Agent方法对模型仿真发现,具有社团结构的有界信任基本模型终态与社团间连通性无关而只取决于交互阈值,只有当社团间有相反的观点领袖时舆论涌现才与社团间连通性密切相关。研究内容有利于理解社团结构对舆论事件涌现的影响。Community structure is another important characteristic besides small world and scare free property of complex networks.A bounded confidence consensus emergency model with community structure was established.After simulation using Multi-Agent method,it is found that the final state of the consensus emergency of basic Deffuant model with community does not relate to community connectivity but depends on the threshold and it relates to community connectivity only when the communities have different opinion leaders.The content contributes to understanding the influence of community structure on opinion emergency.
