宏观经济学微观基础问题的不同视角与本质

On Different Perspective and Nature of the Microfoundations in Macroeconomics

自20世纪60年代以来,宏观经济学的各个分支学科都越来越重视寻找宏观经济理论的微观基础。主流经济学认为,宏观经济理论必须建立在与新古典模型的根本特征相一致的微观经济基础之上;非主流经济学对传统意义上宏观经济学的微观经济基础之争持有很大的怀疑;后凯恩斯主义者认为,真正需要的是微观经济学的宏观经济基础;演化经济理论主张微观基础解释的是社会变迁。文章在对当今微观基础问题争论进行梳理的基础上对宏观经济学体系的内在形成机理和变化趋势进行了探索。

Since the 1960s, various branches of macroeconomics have placed increasing emphasis on seeking the microfoundations for macroeconomic theory. Mainstream economists believe that macroeconomic theory shoud be based on the microfoundation which consists with the basic feature of New Classic model; Non-Mainstream economists adopt a highly skeptical attitude toward the traditional arguments about the microfoundations for macroeconomics; Post Keynesist maintain that we should devote time and energies to macrofoundations for microeconomics; Evolutionary economic theory argue that how to explain the social changes is really the key point. By combing and commenting on the substance of the microfoundation argument, this paper explores the inherent mechanism of formation as well as the change trend for the macroeconomics system.
