功利主义的引入和边际革命使得经济学完成了向新古典范式的转变,但作为核心的效用理论常常被后人理解为是一种心理学的分析。通过对19世纪经济学和心理学的关系进行深入剖析,发现没有明显的证据表明效用理论的建立与发展和心理学有关。新古典经济学虽然以主观价值论为核心,但并没有一个确定的心理学基础,这恰恰是新古典经济学致命的缺陷。

The introduction of utilitarianism and marginal revolution makes the economics paradigm shift to the neoclassical economics,but the utility theory as the core of the new paradigm was later understood as a psychological analysis.Based on analysis on the relationship between the nineteenth century economics and psychology,we can't find clear evidences that may show the relationship between the establishment and development of utility theory and psychology.Although the subjective value is the core of the neoclassical economics,there is no basis from psychology,which is precisely the fatal flaw of neoclassical economics.
