网络社交媒体平台中，政府和网络媒体在内的多个利益相关主体在舆情传播中的交叉影响，决定了突发事件舆情的演化方向，准确掌握舆情多元主体决策行为的博弈演化过程可以提升突发事件舆情治理效力，高效应对突发事件带来的舆情挑战，维护社会稳定与秩序。文章构建突发事件舆情多元主体行为博弈模型，分析各主体在不同情境下的最优决策，使用Python工具模拟仿真不同策略演化路径，验证各主体在不同情境下的决策行为和博弈结果。研究发现，演化博弈理论能够有效解析突发事件网络舆情多元主体决策行为的互作用机理，揭示舆情多元主体行为策略的演变、稳定性及其对舆情发展的影响。

On online social media platforms, the cross-influence of multiple interested subjects including government and online media on public opinion dissemination determines the direction of the evolution of public opinion in emergencies. An accurate grasp of the game evolution of the behavioral patterns in decision making of multiple subjects can increase governance effectiveness and improve the solutions to emergency challenges in public opinion for the purpose of maintaining social order and stability. This paper analyses the best decisions made by each subject in different scenarios by establishing a multi-subject game model of public opinion in emergencies and simulates the game evolution process of public opinion behavior among the government, media, and opinion leaders by using evolutionary game theory and Python tools in order to verify the decision making behaviors and game outcomes of the subjects in different scenarios. Evolutionary game theory can effectively analyze the interaction mechanism of multiple subjects in public opinion under emergency situations, revealing the evolution process of behavior of multiple subjects in public opinion under different conditions.
