认知层次与信念更新对博弈合作行为影响研究

将认知层次模型引入到虚拟博弈中,考察具有异质认知层次的个体,其信念学习与更新规则对协调博弈最终均衡收敛的影响.研究表明:高阶认知层次局中人策略选择依赖于其关于低阶认知层次局中人策略选择的信念;局中人策略选择与其关于对手初始策略选择的信念有关;信念更新与博弈次数影响最终系统的合作水平.

The research on the influence of cognitive hierarchy and belief update on the individuals' cooperative behavior of the game

This thesis is to introduce cognitive hierarchy model into the fictitious play and to research the heterogeneous cognitive levels of individuals. Beliefs learning and update rules have an effect on the final equilibrium convergence of coordination game. Research shows that the high cognitive level player's strategy choice depends on the belief attached to the strategy choice of low order cognitive level; player's strategy choice is related to its belief involved in initial strategy choice of its opponent; belief update and game rounds affect the cooperation level of the final game system.
