Abstract：The behavior of users spreading rumors in social networks is related to their own interests.This paper introduces the penalty function and risk assessment strategy,and constructs a rumor propagation model based on the idea of evolutionary game.Considering that in the process of rumor spreading,users in social networks will learn and imitate to maximize their own interests,this paper uses risk assessment strategy to describe the process of users changing their decisions,and studies the impact of punish-ment mechanism and risk assessment strategy on rumor spreading.On this basis,numerical simulation is carried out on scale-free network and small-world network respectively.The experimental results show that both individual risk assessment and collective risk assessment can effectively reduce the spread of rumors.By increasing the penalty coefficient or reducing the risk threshold,the effect of risk assessment strategy on curbing the spread of rumors can be improved.
