本文认为主流经济学的缺陷是经济分析中忽视了制度安排对资源使用和收入分配的影响。认为主流经济学缺陷产生的原因是其脱离现实的完全理性、完全信息、产品同质的假设及其经济分析中的两分法的局限。忽视了制度安排,主流经济学无法对市场和企业这些制度做出解释,也难以解释现实生活中个体理性和群体理性不一致的资源配置低效率的现象。 This paper argues that the drawback of mainstream economics is the neglect of the impact of institutional arrangements on resource use and income distribution in economic analysis. The main reason for the deficiency of the mainstream economics lies in the fact that it is completely irrational from reality, complete information, the hypothesis of product homogeneity and the dichotomy in the economic analysis. Neglecting institutional arrangements, mainstream economics can not explain the systems of markets and enterprises, and it is difficult to explain the inefficient allocation of resources in individual and group rationality in real life.
