新古典微观经济学能否成为发展经济学的微观基础

Can Neoclassical Microeconomics Provide Microfoundations for Development Economics?

为了在现代经济学理论体系中获得相对独立存在的合理性,发展经济学必须建立在严格的微观理论基础之上,但这并不意味着它必须以新古典微观经济学为其微观基础。本文试图阐明,新古典微观经济学的分析空间是一个均衡分析空间,它或许适合于研究处于均衡或近均衡状态的经济体,但不足以分析远离均衡的发展中国家经济。从某种意义上说,新古典微观经济学可以看作是一般的"经济生理学",而发展经济学的微观基础应该是"欠发达经济病理学"。

In order to win the legitimacy of a relatively independent existence in its own right in the field of modem economics, development economics must indeed be based on rigorous microeeonomie foundations, but this does not imply that it must take neoclassical microeeonomics as its microfoundations. This paper tries to clarify that standard neoclassical mieroeeonomies sets up an equilibrium analysis-space and maybe can deal with the normal state of economies which are at or near equdibrium, but it is not adequate for analyzing developing economies in far-from-equilibrium. In a sense, neoclassical microeeonomies can be viewed as a ＂physiology of economy＂, and the mierofoundations of development economics can be considered ＂pathology of the underdeveloped economy＂.
