情绪影响下群体性冲突的RDEU博弈模型分析

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 emotion impact on the behavior of players in Game Theory, the RDEU Game model of group conflict was built, involving the rank-dependent utility theory. Moreover, the existence of Nash Equilibrium under different emotional states was and disecused the behavioral mechanism of players' mixed strategy choice influenced by emotion was analyzed in this paper. The findings demonstrate that emotion has significant impact on Game Equilibrium of group conflict. When the player has a “pessimistic” emotion, he or she tends to choose the behavior of resisting. Similarly, the player tends to submit to the other player when he or she holds the emotion of optimist. It was also found that players could be influenced by a certain judgment made by the other player, who was driven by emotion when selecting strategies. For example, when vulnerable groups think that if the probability of the opponents' adopting a repressed strategy is below a certain cut-off point, the probability of their choosing resisting strategy will increase, with the optimism index of emotion generating higher levels, At last, the conclusions were analyzed numerically, taking an example of house dismantlement conflict.
