摘　　要：经济人概念经历了一个逐渐演变的过程:早期是内含特定社会伦理关系的自利人,后来由抽象原子化的经济人所取代,接着演变为更中性的理性人;理性的原意也仅仅体现为实现特定目的的有效手段选择,后来却蜕变为行为的一致性问题。正因为理性内涵的不断演变及其外延的不断扩大过程,以致经济人概念成了一个同义反复;结果,经济人假设在强化经济学分析框架的同时,也使得经济理论与现实之间越来越相脱节。The concept of economic-man has experienced a gradual-evolution process. It can trace back to self-interested man that incarnates a special ethic relation, and then self-interested man is substituted by the abstract concept of economic man which evolved into more neutral rational man later. The original intention of rationality only reflects an effective method choice to realize special aims and then has been changed into the consistency issue. Due to the expansion of the connotation and extension of rationality, the concept of economic man has become a tautology. As a result, the hypothesis of economic man makes the divorce between economic theories and the real world more serious while it improves the economical analytical framework.
