现代主流经济学的经济人假设以早期还原主义心理学为理论基础,它仅仅反映了动物性的本能需求而忽视了人类的社会性;因此,它不仅无法揭示“无形的手”来自何处以及如何运作,也无法根本上理解“囚徒困境”与现实相悖的现象。相反“为己利他”行为机理则以新近人本主义心理学为理论基础,它将人类基于动物性的本能目的和基于社会性的实现手段结合起来;因此,它可以更好地挖掘“无形的手”是如何运作而实现社会协调,从而是比经济人假设更合理、有效的人性抽象。
Economic man hypothesis in the modern mainstream economics takes the early reductionism psychology as its theoretical basis. It just reflects animal instinct needs but neglects the social nature of man. As a result, the hypothesis can not reveal where the"invisible hand" comes from and how it works, nor does it have a fundamental understanding of the paradox of "Prisoner's Dilemma" and the reality. In contrast, the behavior mechanism of"self-interest and altruism" takes the latest hu- manistic psychology as its theoretical basis and combines man's instinct purpose as animal with the means of achievement based on social nature. As a result, it can better finds how the"invisible hand" works for social coordination. The mechanism has more reasonable and more effective human abstract than economic man hypothesis.
