自1991年以来美国经济呈现快速增长势头,年均增长率高居3-4%,失业率下降到仅为4.2%左右,通胀率降低到1.5%的超低水平,到2000年2月经济持续增长超过106个月。新的经济现象引出了一系列经济学新问题,各派围绕这些问题各抒己见,莫衷一是。主要争论的问题可以归纳为以下几点: 一、新经济是否已经到来,经济周期是否依然存在。针对上述经济现象,一些美国学者提出:美国已进入新经济时代。美国《商业周刊》主编斯蒂芬谢波德这样界定“新经济”的特征:实际GDP大幅增长,公司运营利润上升,失业率低,通胀率低,进出口之和占GDP的比例上升,经济增长中高科技的贡献率上升。如果谢波德的定义仅限于表层次的经济指 The U.S. economy has enjoyed rapid growth since 1991, with an average annual growth rate of 3-4%, an unemployment rate of 4.2% and an inflation rate of 1.5%.

The definition of “new economy” by the editor in chief of Business Week Magazine in the United States is that the real GDP has risen sharply, the operating profit of the company has risen, the unemployment rate has been low, the inflation rate has been low, the ratio of imports and exports to GDP has risen, The contribution rate of science and technology has risen.
