摘　　要：随着互联网的快速发展,大众已经习惯在网络上分享兴趣爱好,获取信息和讨论常见热点话题,研究多层社交网络的舆情传播规律有利于舆情分析和舆情治理.文章基于传统的SEIR传染病模型,考虑了节点重要性对传播概率的影响,引入动态参数,构建单层网络舆情传播模型,同时考虑到不同时间步长和度度相关性对舆情传播的影响,提出了一个多层网络交叉传播的舆情传播模型.文章对多层网络舆情传播模型的多种传播性能和规律进行了理论验证和实验分析,实验结果表明时间步长和度度相关性对舆情传播有着显著的影响.最后,有针对性地提出了一些舆情治理机制和舆情应对措施,这些措施可以帮助政府和相关管理部门提高舆情管理的效率,确保在舆情事件中能够迅速做出响应,降低潜在的负面影响,具有重要的意义.With the rapid development of the Internet,people have become accus-tomed to sharing hobbies,obtaining information and discussing common hot topics on the Internet,studying the law of public opinion communication in multi-layer social networks is beneficial to public opinion analysis and public opinion governance.Based on the traditional SEIR epidemic model,this paper considers the infuence of node importance on propagation probability,and introduces dynamic parameters,and con-structs a single-layer network public opinion propagation model.At the same time,considering the impact of different time steps and degree correlations on public opin-ion propagation,a multi-layer network cross propagation public opinion propagation model is proposed.In this paper,theoretical verification and experimental analysis are carried out on various communication performances and laws of multi-layer network public opinion communication model.Experiments show that time step and degree correlation have a significant impact on public opinion communication.Finally,some public opinion governance mechanisms and public opinion response measures are put forward,which can help the government and relevant administrative departments to improve the efficiency of public opinion management,ensure rapid response in public opinion events,and reduce potential negative effects,and this is of great significance.
