问题如下：
A country with a persistent trade surplus is being pressured to let its currency appreciate. Which of the following best describes the adjustment that must occur if currency appreciation is to be effective in reducing the trade surplus?选项：
A.Domestic investment must decline relative to saving. B.Foreigners must increase investment relative to saving. C.Global capital flows must shift toward the domestic market.解释：
The trade surplus cannot decline unless the capital account deficit also declines. Regardless of the mix of assets bought and sold, foreigners must buy more assets from (or sell fewer assets to) domestic issuers/investors.
中文解析：
除非资本账户赤字也下降，否则贸易顺差不可能下降。无论购买和出售的资产组合如何，外国人必须从国内发行人/投资者那里购买更多的资产(或出售更少的资产)。
如题、看了另一个解释还是没懂为什么capital account 一定要增加
