摘要
现代经济学与现代生物学对人性的看法相当一致,都把自利看作人类行为的基本前提。但来自桑塔费学派的最新研究证明,在人类进化的早期阶段,利他行为作为社会规范内部化的产物,在维持个人之间的合作劳动、有效提高族群生存竞争能力方面,具有不可替代的重要作用。我们在ESS(即“进化稳定策略”)基础上提出一个演化均衡模型,进一步解释了利他行为的进化优势以及合作剩余导致利他偏好内生的机制。
Today ＇s economics and biology agree with each other on the nature of human. They take the self-interest as the premise of human＇s behaviors. The latest report from Santa Fe school implies that during the early phase in the human evolution the altruism behaviors as the social norm endogenetic result, played an important role in maintain the cooperation among individuals and improved the ability in group survival competition. We work out an evolutive equilibrium model based ou ESS, in order to explain the advantage of the altruisnt behaviors and the cooperation surplus induced mechanism for the altruism preference to get endogenctic.
