B.increase in net export. C.a increase in tra ficit B is correct.The fiscbalanequation is given as: (G-T)=(S-I)-(X-M), increase in government ficit (G-T) is a combination of increase in private saving over private investing (S-I) ana crease of tra ficit or net export (X-M).考点Relationship between Income ApproanExpenture Approach解析 财政平衡方程为:(G-T)=(S-I)-(X-M)，政府赤字(G-T)的增加的同时，私人储蓄增加超过私人投资(S-I)，或者贸易赤字或净出口(X-M)减少，所以AC不入选，B入选。 按照解析的思路“财政平衡方程为:(G-T)=(S-I)-(X-M)，政府赤字(G-T)的增加的同时，私人储蓄增加超过私人投资(S-I)，或者贸易赤字或净出口(X-M)减少”c为“tra ficit增加”，所以是not a factor？
