答案解释中capital outflow是什么意思？怎么理解
NO.PZ2016010802000095 问题如下 Because of a sharp cline in reestate values, the householsector hincreasethe fraction of sposable income thit saves. If output aninvestment spenng remain unchange whiof the following is most likely? A.A crease in the government ficit. B.A crease in net exports anincreasecapitinflow. C.increase in net exports anincreasecapitoutflow. C is correct.The funmentrelationship among saving, investment, the fiscbalance, anthe tra balanis S = I + (G – T) + (X – M). Given the levels of output aninvestment spenng, increase in saving (rection in consumption) must offset either increase in the fiscficit or increase in net exports. Increasing the fiscficit is not one of the choices, so increase in net exports ancorresponng increase in net capitoutflows (increaselenng to foreigners anor increasepurchases of assets from foreigners) is the correresponse.考点解析 一国G可以通过支出法表示 Y=C+I+G+X-M，也可以通过收入法表示 Y=C+S+T ，讲上述两者联立，可得S=I+(G-T)+(X-M)依据上式，净出口的增加可以导致储蓄S的增加，所以C入选B不入选。财政赤字增加而非减少对应S的增加，所以A不入选。 是G-T表述财政赤字吗？还是要考虑其他因素 。
