Abstract Considering the phenomenon that false information is diffused before real information in social networks, an information competition diffusion model is studied and the effects of different probabilities, the initial diffusion time of real information and the number of real information spreader nodes are analyzed and compared. It is found that reduing the probability of unknown nodes to diffuse false information can reduce the diffusion scope of false information. In addition, only when the delay diffusion time of real information is short, can the diffusion scope of false information be reduced and the coverage of real information be increased by increasing the probability of nodes to diffuse real information, increasing the initial number of real information spreader nodes and selecting nodes with greater degree to diffuse real information.
