“经济人”假定是西方主流经济学中的一个重要前提和分析工具,不同派别和不同经济学家对其进行了阐释。经济学的发展逐渐暴露了这一假定的内在缺陷。不论是从人性基础、方法论角度,还是从经济理论的现实性角度,旧的“经济人”假定都存在着不合理性。中国经济学的重建需要一个新的“经济我”假定。 The “economic man” hypothesis is an important prerequisite and analytical tool in the mainstream Western economics, which is interpreted by different factions and economists. The development of economics gradually exposed the inherent defects of this assumption. From the perspective of human nature, methodology and reality of economic theory, the old “economic man ” assumes that there is irrationality. The reconstruction of China’s economy needs a new “economic me” assumption.
