[目的/意义]随着移动互联网络的发展，网民的个体、群体社交方式愈加丰富，多样的社交关系共同形成了复杂的信息传播网络，在此环境下探究真假信息的竞争传播，对于完善信息治理手段、形成良好的网络信息生态具有重要的现实意义。[方法/过程]结合复杂网络理论构建好友与群友耦合关系网络，分析信息传播影响因素，运用拓展的SIR模型建立基于耦合关系网络的真假信息竞争传播模型，并通过仿真实验对比分析了影响因素对真假信息竞争传播的影响。[结果/结论]基于耦合关系网络的真假信息竞争传播中，网络结构、信息发布时间和可信程度、用户媒介素养会对真假信息的竞争传播产生明显影响，能够在很大程度上影响耦合关系网络的真假信息竞争传播结果。

[Purpose/significance] With the development of mobile Internet, the modes of individual and group commu⁃nication have become increasingly diverse, and various social relationships together form a complex information com⁃munication network. In this environment, exploring the competitive communication of true and false information has great practical significance for improving the governing measures of information and forming a good network informa⁃tion ecology. [Method/process] Based on the complex network theory, this paper constructs the coupling relationship network between individual contacts and group contacts, and analyzes the influencing factors of the information commu⁃nication. The extended SIR Model is used to establish the competitive communication model of true and false informa⁃tion based on the coupling relationship network, and through simulation experiments, the impacts of various influenc⁃ing factors on the competitive communication of true and false information are compared and analyzed. [Result/conclu⁃sion] In the competitive communication of true and false information based on coupling relationship network, the net⁃work structure, information issue time, credibility degree, and user media literacy have obvious effects on the competi⁃tive communication, and they can greatly affect the competitive communication result of true and false information based on coupling relationship network.
