问题如下:
A surplus on capital account means
选项:
A.how a nation funds an excess of investment and government spending over domestic saving plus taxes.
how a nation deal with domestic saving plus taxes that excess investment and government spending.
C.investment and government spending equal to domestic saving plus taxes
解释:
A is correct.
(X – M) = (S – I) + (T – G)
X-M代表了经常性账户,又因为资本账户和经常性账户刚好相反,所以-(X-M)就是资本账户。
-(X-M)增加,表明I-S增加,或者G-T增加。这时候表明国内储蓄不能支持投资,税收不能支持政府支出。那么不足的部分就得靠资本账户的外资支持。所以A选项说法正确。
为什么说了capital account surplus, 还要去看current account情况呢?直接看capital account,即(S-I) + (T-G), 现在说surplus,那么(S+T) > (I+G), 为什么答案会说是excess of investment and government spendng over saving plus taxes, 不是反了吗?
