解析
C is correct.
The fundamental relationship among saving, investment, the fiscal balance, and the trade balance is S = I + (G – T) + (X – M). Given the levels of output and investment spending, an increase in saving (reduction in consumption) must be offset by either an increase in the fiscal deficit or an increase in net exports. Increasing the fiscal deficit is not one of the choices, so an increase in net exports and corresponding increase in net capital outflows (increased lending to foreigners and/or increased purchases of assets from foreigners) is the correct response.
考点：
解析： 一国GDP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选项入选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。
老师，这如果净出口增加，代表出口增加或者进口减少，那不应该代表capital inflow么？出口代表国外跟国内买，外面钱流进来，所以不应该是capital inflow么？
