宏观经济波动的实体性成因——真实经济周期(RBC)理论评析

Substantive Cause of Macroeconomic Fluctuations:Real Business Cycle(RBC)Theory

真实经济周期理论属于西方经济学中的经济自由流派。它突破了货币周期理论,把来自供给方面的技术冲击等意外真实冲击看作是经济波动的根源;认为经济波动不是对长期经济增长趋势的偏离,否定把宏观经济分为长期和短期的观点;坚持货币中性主张;反对政府的干预政策。它以正统的微观经济理论来说明宏观经济波动,改变了人们对经济周期性波动原因的理解,超越了货币主义和新古典宏观经济学,是20世纪80年代以来自由主义经济学的重大发展。

Real business cycle theory belongs to the Liberal School of the western economics. It breaks through the monetary cycle theory, and takes the accident real impacts such as the technology impact from supply aspect as the cause of economic lfuctuations, and denies the views that economic lfuctuation is a deviation from the long-term economic growth trend and macro economy can be divided into long-term and short-term. RBC theory insists on currency neutral position and against the government＆#39;s intervention policies. It illustrates the macroeconomic lfuctuations by the orthodox microeconomic theory, and changes people＆#39;s understanding on the reasons for economic cyclical lfuctuation, and then transcends the monetary doctrine and new classical macroeconomics. We could say that RBC theory is major development of liberalism economics since the 1980s .
