美国的巨额贸易赤字经常被作为美国经济实力相对下降的“指标”之一。本文认为，传统的统计方法仅统计商品贸易，未统计服务贸易和海外直接投资的收益，是造成巨额赤字的主要原因。若考虑到后二者的因素，则逆差将大大减少。长期以来美国有意夸大其贸易逆差，以达到向别国施加压力，扩张市场的目的 The huge trade deficit of the United States is often used as one of the “indexes” of the relative decline in the U.S. economic power. This paper believes that the traditional statistical method only counts the trade in commodities, and does not count the revenue from service trade and overseas direct investment, which is the main reason for the huge deficit. If you take into account the latter two factors, the deficit will be greatly reduced. For a long time, the United States has intentionally exaggerated its trade deficit so as to exert pressure on other countries and expand the market.
