此轮美国经济增长表现出与以往诸多不同的特征,预计未来一段时间,“温和增长、低通胀、低劳动参与率、社会分化拉大”将成美国经济的“新常态”。这一趋势的实质是美国经济处于结构转型期与技术创新积聚期叠加的新阶段。美国经济“新常态”持续时间将取决于美国经济何时成功转型及重大技术革命何时出现。“新常态”短期有利于其维护霸权,但会延长美国对中国赶超焦虑期,令中国面临更长时间的战略压力。 This round of U.S. economic growth has shown many different characteristics from the past. It is expected that “moderate growth, low inflation, low labor force participation and social stratification” will become the “new normal” for the U.S. economy in the coming period. The essence of this trend is the new phase in which the U.S. economy is superimposed with the period of structural innovation and the accumulation of technological innovation. The U.S. economy “the” new normal “duration will depend on when the U.S. economy is successfully transformed and when significant technological revolutions will take place. ”New Normal " will help maintain its hegemony in the short term, but will prolong the U.S. anxiety over the catch-up in China and put China under more strategic pressure for a longer period of time.
