后凯恩斯学派微观基础研究的新进展

Review on Some Recent Advances of Post Keynesian Economics in Micro-Foundation Research

尽管在后凯恩斯学派内部仍存有诸多分歧,但后凯恩斯学派近年来实已形成了一个比较明确的微观分析框架。这就是以个人分析和阶级分析相结合的方法,考察在非遍历、不确定的社会经济环境和不完全竞争的市场条件下,个人或集团追求自身利益最优化的行为对总需求与就业状况的影响,从而强调宏观经济失衡的市场失灵病根。研究表明,这一分析框架既不同于凯恩斯主流经济学、新凯恩斯经济学,也不同于新古典宏观经济学,甚至与新奥地利经济学也存在重要差异。后凯恩斯学派的研究成果,对提升中国经济学的研究水平和促进中国经济体制改革的进一步深化均有重要的借鉴意义。

As a distinctive school of thought in economics, Post Keynesian economics have ever made important contributions to contemporary economic theory and policy. In recent years, they again acquired some significant advances in micro-foundation research. This article will profoundly survey on these new advances, and then try to discuss what we can draw out from these advances for our economic theory and policy research in China. In section one we reconsider the characters and meanings of Post Keynesian micro-analysis during the ＂Anti-Marginalist revolution＂; In section two we give a systematic analysis on the major advance of this school in micro-foundation in recent years; and finally, in section three, we will explain why we should pay more attention to Post Keynesian and what we can learn from their theoretic system and policy proposition.
