目前,对美国经济的发展趋势存在着两种不同的看法: 一种认为,美国经济正在向传统的经济周期理论和西方经济学理论挑战。如,菲利浦斯曲线不能在低通胀率和低失业率下长期并存,但美国经济在低通胀率和低失业率的情况下,以连续102个月的持续增长记录,改变了经济增速、通货膨胀与失业之间的关系。 At present, there are two different views on the development trend of the U.S. economy. One is that the U.S. economy is challenging both the traditional economic cycle theory and Western economic theory. For example, the Phillips curve can not coexist for a long time with low inflation and low unemployment, but the U.S. economy recorded a continuous 102-month record of sustained growth with low inflation and low unemployment, which changed the economic growth rate , The relationship between inflation and unemployment.
