有学者认为,美元贬值有利于美国解决“双赤字”问题,并增强美国出口产品的国际竞争力,减少贸易逆差。这与美国财政部长保尔森“强势美元最符合美国国家利益”的观点,显然是相左的。另外,美元持续走弱,将直接造成各国美元资产的相对价值下降,为避免损失,各国已纷纷开始进行外汇? Some scholars believe that the devaluation of the U.S. dollar will help the United States to solve the problem of “double deficits” and enhance the international competitiveness of U.S. exports so as to reduce the trade deficit. This is clearly contrary to the view taken by the U.S. Treasury Secretary Paulson that “a strong dollar best matches the interests of the United States.” In addition, the continuous weakening of the U.S. dollar will directly cause the relative value of U.S. dollar assets in various countries to drop. To prevent losses, all countries have started to carry out foreign exchange one after another.
