Rich countries, by contrast, are able to export more capital-intensive goods, and thus have a greater need for investment. So they may be importing more capital – resulting in a greater current-account deficit – simply because they are producing more capital-intensive goods.
相反，富国则可以出口资本更为密集的产品，因此拥有更为强劲的投资需求。于是他们可能仅仅因为生产资本密集型产品而要进口更多的资金——从而导致经常账户赤字的增加。
