美国依然是世界上的经济霸主,美元也依然是世界上最为主要的国际性货币。各个国家在不同的历史时期都大量的持有美元作为自己的外汇储备,因此美元对外汇率的变化影响着、牵动着各个国家的经济政策。分析美元对外汇率的发展不仅可以反映出美国自身的经济发展,更能够深层次的显示出美元对于世界经济的影响。 The United States remains the dominant economic power in the world and the U.S. dollar remains the dominant international currency in the world. Since each country holds a large amount of its own foreign exchange reserves in different historical periods, changes in the U.S. dollar’s foreign exchange rate affect the economic policies of various countries. Analyzing the development of the U.S. dollar against foreign exchange rates can not only reflect the economic development of the United States itself, but also reveal the impact of the U.S. dollar on the world economy at a deeper level.
