对理性人假设批判的批判
Criticism of the critique of rational man hypothesis

理性人假设是经济学大厦的基石之一。自其提出之日，就遭到学者广泛而激烈地批评，但似乎并没有妨碍以理性人假设为基础的个人主义分析方法攻城掠地，形成目前庞大的经济学帝国主义，直至目前，也没有看出它放慢侵略的步伐。在表象背后，必然有对理性人假设的现实需求，必然存在其内在合理性和重要价值性：首先，理性人假设是一种方法论逻辑，为科学研究所必须；其次，理性人假设是追求最大化，而非实现了最大化，梦想能否实现是受制度、技术、文化等现实的约束；再次，相比其他人性假设更接近现实，它为社会治理提供一种可能的进路；最后，它是激励约束制度设计的前提。
The rational man hypothesis is one of cornerstones of economics mansion. Since its being proposed, it has received wide and fiercely criticism by Scholars. But it did not seem to impede the individualism analysis method that was based on the rational man hypothesis branching out, and to form into the huge economic imperialism. Until now, it also didn’t seem to slow down the pace of aggression. Behind appearances, it must have the reality needs of the rational man hypothesis, and the intrinsic rationality and important value. Firstly, rational man hypothesis is a kind of methodology logical that is necessary for scientific research. Secondly, the rational man hypothesis is to pursue of maximizing, rather than to maximize, and whether the dream realization can realize depend on system, technology, culture and other reality. Moreover, compared to other human nature assumption, it is closer to reality and provides a possible approach for the social governance. Finally, it is the precondition of incentive constraint system design.
