摘要
分析了谣言传播的心理学机制和敌我双方的对抗策略,引入谣言属性变量并藉此建立了平均场下的谣言传播新模型.借助严格一阶随机占优和严格二阶随机占优的概念分别讨论了谣言属性、敌我双方干预强度、网络结构特征和谣言传播效果之间的关系,提出并证明了具有重要管理意义的4个命题.通过仿真实验进一步验证了命题的正确性.
The psychological mechanism and intervening strategies of rumor propagation were analyzed firstly. Using mean field approximation, we gave a new model in which rumor attribute was considered. By introducing strictly first order stochastic dominance and strictly second order stochastic dominance, we analyzed the relationships among rumor attribute, intervening intensity, network structure and diffusion effect, then derived and proofed four propositions that were very useful for us to explore rumor propagation. Finally, some propositions were verified by computer simulation.
