摘　　要：本文在基于小世界网络理论SIR模型分析的基础上,构建出一种对微博网络负面信息传播的扩散机制模型,利用数学建模对该模型传播趋势进行概率分析,研究发现微博网络社区的节点度越大,该节点处负面信息传播的能力就会越强;并通过对微博负面信息义乌"微笑哥"之谜进行社会网络实证分析,对节点用户中心度的刻画,说明了微博内负面信息的传播会因其网络内节点的不同而呈现不同的扩散特征。Based on the study of the small-world network SIR theory model,this paper constructed a diffusion mechanism model of micro-blogging negative information dissemination,and at the same time,through a probability analysis on spread trend through mathematical modeling,the study founds that： the bigger of the node’s degree in micro-blogging network,the stronger ability of the negative information’s dissemination; Farthermore,the theoretical method of this paper was tested by a case of micro-blogging negative information named yiwu ＂Smile＂ mystery through social network analysis,and illustrated the spread’s characteristics of negative information would be different due to the degree of each node in micro-blogging network.
