本文认为,目前,美国对世界经济的影响力已经有所下降。从短期看,美国经济复苏还面临一些困难,但从中期看,新能源和制造业可能成为美国经济的引擎。对中国而言,高利率和高汇率可能使中国经济增长放缓,中国应警惕美国股票和债券市场的潜在风险。 This article argues that at present, the U.S. influence on the world economy has declined. In the short term, the U.S. economy still faces some difficulties in its recovery. However, in the medium term, new energy and manufacturing may become engines for the U.S. economy. For China, high interest rates and high exchange rates may slow China’s economic growth and China should be alert to the potential risks in the U.S. stock and bond markets.
