[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.
