考点：The Trade Balance
解析：
解析：经常性账户和资本账户是此消彼长的两个账户。
经常账户与资本平衡。经常性账户赤字消失，那么资本账户盈余也必须消失。这代表资本流出国内涌入国外市场，C选项正确。
依据公式（X-M）=(S-I)+(T-G)。
投资I增加，等式右边变小，左边也会相应变小，经常性账户赤字还会增加，A选项错误。
储蓄S减小，等式右边变小，左边也会相应变小，经常性账户赤字扩大，所以B选项错误。
题干里 trade deficit tends to depreciate its currency.的意思是，经常性项目的贸易赤字缩小吗？相当于经常项目增加，所以才需要资本项目减少是吗？
