摘要：Officials always want to use the replacement relationship between the unemployment rate and the price of the Phillips curve to reduce the unemployment rate, but things go crisscross. The reason is that there is no causal relationship between price and unemployment. In this paper, it demonstrates the Phillips curve is derived from the unemployment cycle equation and the inflation equation. And then, it discusses the influence of core variables and fluctuating variables on Phillips curve and the cause of distortion or complete disappearance of Phillips curve. Finally, this paper discusses monetary neutrality and related monetary policy issues. The policy that is conducive to the smooth operation of the system is consistent with the constant money supply of the economic cycle, rather than counter-cyclical regulation.
