The　hot　events　of　the　internet　public　opinion　spread　fast　and　have　great　influence.　It　has　become　a　topic　of　concern　for　netizens　and　governments.　The　spread　of　hot　spots　on　the　internet　is　similar　to　the　dynamics　of　infectious　diseases,　so　a　traditional　SIRS　epidemic　model　based　improved　model　is　proposed,　combining　the　analysis　of　the　game　theory.　The　evolutionary　game　model　of　infectious　body　and　immune　body　is　constructed,　the　equilibrium　point　of　the　game　is　found　and　the　law　of　the　spread　of　hot　spots　is　obtained.　The　model　is　verified　by　experiment　through　the　specific　network　hot　events,　and　the　actual　data　simulation　analysis　is　carried　out　through　different　parameters.　The　propagation　law　of　hot　spots　is　obtained　through　the　experiments,　and　the　countermeasures　and　suggestions　for　the　control　of　the　hot　spot　events　are　provided.　©　2018,　The　Editorial　Board　of　Journal　of　System　Simulation.　All　right　reserved.
