[Objective] This paper aims to study the mechanism of media collaboration in topic propagation and its application in guiding and controlling the dissemination of public opinion topics. [Methods] Using the method of simulation, the model of public opinion topic propagation under the media synergy effect was constructed, and the influence mechanism of the medium that played synergy, and the time point and duration of its effect on the dissemination of public opinion topics were explored. [Results] The simulation results show that, compared to single media, the collaborative network constructed by multiple media plays a stronger role in promoting topic communication, and is affected by the media intervention time and the media duration. [Limitations] In the simulation experiment, the Internet public opinion carrier network is a real network, but the media collaboration network and topic communication data are all from simulation. [Conclusions] The collaboration between media is an important expression of media in the propagation of topics. The rational use of its synergies is conducive to controlling and guiding the dissemination of public opinion topics scientifically and efficiently.
