摘要
二战后美国经济周期波动发生显著变化。相比二战之前,美国经济周期扩张期拉长,衰退期缩短,二者之间形成剪刀差。经济周期长度、扩张期跨度和紧缩期跨度的离散度远远大于战前。二战后至今,美国经济中周期出现(朱格拉周期)呈拉长的趋势,扩张期远远长于衰退期,中周期(朱格拉周期)和短周期(基钦周期)的波幅经历了从小到大的阶段性变化。
The pattern of its economic circular fluctuations in U. S. changed significantly. Compared with prewar business cycles, the U.S. expansionary phase of the business cycle are lengthening and the period of recession shortening, forming scissor gap between them. And the length of a business cycle, the dispersion of expansion and recession span is far greater than that prewar. Since World War II, the U. S. mid-economic cycle （Juglar cycle） has an elongating trend, and expansion period is far longer than recession period. While, Juglar cycle and short-cy- cle （Kitchin cycle） are experiencing a change from shortening to lengthening.
