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。
想问一个没太想明白的问题,为什么总支出是等于C+I+G再加上净出口(X-M)而不是加上(M-X)??进口花的减去出口赚的不才是支出吗?
