摘　　要：一直以来,个体理性与集体理性存在矛盾,其原因就在于个体理性的一元性,只包含了个体的自利理性。本文通过对个体理性的二元性假设,提出个体理性包含自利理性和社会理性两个方面,由此可以解决个体理性与集体理性之间的矛盾。文章通过对囚徒困境模型一次博弈和长期博弈的重新分析,利用仿真方法,论证了个体的社会理性在群体发展演化中的作用。The contradiction of the individual rationality and collective rationality lies in the individual rationality contains only the selfish rationality. Through the individual rationality of duality hypothesis, the article supposes that individual rationality is composed of the selfish rationality and the social rationality two aspects, so the contradiction can be solved. Based on the assumption of individual binary rationality, research on the prisoners＇ dilemma model again, and uses the multi-agent simulation method to analyze the evolution game model, demonstrates that the social rationality in social evolution is very important.
