本文认为，工资价格刚性问题是新凯恩斯主义的中心问题。依照对这一问题的认识，大体上可把这一流派分为三个主要支派，即名义则性学派、实际刚性学派和非刚性学派。本文对这三个支派的主要观点和相互关系作了较为系统、全面的介绍。文章认为，新凯恩斯主义强调失业和经济波动的微观基础，这比传统的凯恩斯主义宏观经济学无疑前进了一步，但绝大多数新凯恩斯主义者都只满足于提出对经济波动和非自愿失业现象的解释，而拿不出解决这些问题的办法。这一流派所提出的理论往往带有片面性、“庸俗性”等特点，另外，这一流派目前尚处于发展过程中，还没有形成完整的理论体系，实际上是由多个支派、多种学术观点拼合成的大杂烩。
This paper argues that the rigidity of wage prices is the central issue of New Keynesianism. On the basis of understanding of this issue, the genre can generally be divided into three major tribal schools: the nominal school of thought, the practical school of rigidity and the non-rigid school of thought. This article gives a more systematic and comprehensive introduction of the main points and interrelations of the three tribes. The article argues that the new Keynesian stress the micro foundation of unemployment and economic fluctuations is no doubt one step further than the traditional Keynesian macroeconomics, but the vast majority of New Keynesians are only satisfied with the proposed economic fluctuations and involuntary unemployment But can not find a solution to these problems. The theory put forward by this school is often characterized by one-sidedness and vulgarity. In addition, this school is still under development and has not yet formed a complete theoretical system. In fact, it is composed of various tribes, Opinion mixed into the hodgepodge.
