摘　　要：[研究目的]突发公共事件下社交媒体虚假信息治理问题亟需解决。该文旨在探索社交媒体虚假信息自净化的最优博弈演化路径,充分发挥自净化机制在突发公共事件虚假信息治理中的作用。[研究方法]基于演化博弈方法,构建社交媒体虚假信息自净化的三方动态博弈模型,重点分析了主体稳定策略的均衡条件及模型均衡点,并进行仿真分析。[研究结论]博弈过程存在四个策略均衡点,且均可达到虚假信息自净化。知情者和意见领袖,二者之一参与净化过程即可实现虚假信息自净化,且知情者提供真相产生的影响作用显著大于意见领袖的引导作用,凸显了知情者在虚假信息自净化中的重要地位。最后提出相应的对策与建议。[Research purpose]The problem of social media disinformation governance under public emergencies needs to be addressed urgently.The purpose of this paper is to explore the optimal game evolution path for self-purification of social media disinformation and to give full play to the role of self-purification mechanism in the governance of disinformation in public emergencies.[Research method]Based on the evolutionary game method,a three-party dynamic game model for the self-purification of social media disinformation is constructed,focusing on the equilibrium conditions of the subject's stabilization strategy and the equilibrium point of the model,and simulation analysis is conducted.[Research conclusion]There are four strategic equilibrium points in the game process,and all of them can achieve disinformation self-purification.One of the two,the informed and opinion leaders can participate in the purification process to achieve disinformation self-purification,and the influential role of the informed in providing the truth is significantly greater than the guiding role of the opinion leaders,highlighting the important position of the informed in the self-purification of disinformation.Finally,we propose corresponding countermeasures and suggestions.
