凯恩斯主义和供给学派排他式主导政策选择的缺陷

The Defects of Selection of Exclusive Dominant Policy of Keynesianism and Supply-Side Economics

凯恩斯主义和供给学派都有自己形成的特定历史条件。统一于西方经济学的这两个学派,在假设和理论逻辑起点上是对立的,前者以需求决定供给为起点,后者以供给创造需求为起点,因而互不相容,把需求管理与供给管理对立起来,在政府和市场手段的使用上也存在分歧。两个学派的假设和理论逻辑与现实不一致,都回避资本主义生产方式及其矛盾,而主要是在既定的资本主义生产方式下讨论需求、供给及相互之间的关系。这两个学派是解救不同原因所致资本主义经济危机的药方,其理论和政策主张在实践中的运用,解救了旧有经济危机之后,又衍生出新的经济危机。两个学派解救危机成效的光环及革命之革命的理论演进思维定式,对其假设、理论逻辑与现实不一致及导致新危机的问题有所屏蔽,对此应还其本来,不能将其中的某个学派作为排他式单一主导一国经济政策选择的理论依据。

Both Keynesianism and Supply-Side Economics have their own specific historical conditions in their formation. The two schools, on the assumption and the theoretical logic starting point, are opposite. The former takes the demand as the starting point, and the latter takes the supply to create demand as the starting point, which are incompatible with each other. The two schools are taken as the prescription to rescue the economic crisis of capitalism caused by different causes. Their theories and policies advocated in practice have saved the old economic crisis while deriving new economic crisis. The aura of the effect of the two schools in rescuing the crises and the evolution of their revolutionary theories, has obscured the problems in their assumptions, theoretical logic and inconsistent with the reality. In this regard, we should restore their true colors and should not take one single school as the theoretical basis for the selection of exclusive dominant policy of one country.
