考虑到情绪因素对参与者行为的影响,基于等级依赖期望效用理论框架构建了群体性冲突的RDEU博弈模型,讨论了不同情绪状态下的博弈纳什均衡的存在性,分析了情绪因素对参与者选择混合策略的行为机理。研究发现:情绪因素对群体性冲突的博弈均衡有着显著的影响,当博弈参与者具有“悲观”情绪时,倾向于“对抗”性的行为,当参与者具有“乐观”情绪时,易于做出“让步”性的行为。在情绪的驱动下,参与者还会受到对方采取某个策略的判断的影响,如当弱势群体认为对手采取“压制”策略的概率低于某个分界点时,随着乐观情绪指数的增大,其选择“对抗”策略的概率将随之增大。最后,以房屋拆迁群体性冲突为例,数值分析了博弈模型的结论。
Considering the influence of emotion on participants’ behavior, this paper constructs the RDEU game model of group conflict based on the theory of grade-dependent expectancy utility, discusses the existence of game Nash equilibrium under different emotional states, and analyzes the influence of emotion on the choice of participants Mixed strategy behavior mechanism. The study found that: Emotional factors have a significant impact on the game equilibrium of group conflict. When game participants have “pessimistic” emotions, they tend to behave “confrontationally.” When the participants have “optimism” Emotions, easy to make “concessions ” sexual behavior. In the emotion-driven, the participants will also be subject to the other side to take a strategy of judgments, such as when the disadvantaged groups that opponents to take “suppression ” strategy is below a certain point of probability, with the optimism index Increase, the probability of its choice “confrontation ” strategy will increase. Finally, taking the group conflict of house demolition as an example, the conclusion of the game model is analyzed numerically.
