众所周知,从90年代初起,美国经济一直以年均4％左右的速度高速增长着,并奇迹般地持续了近10个年头,成为美国经济史上最长的扩张时期。随着经济持续快速增长,美国经济实力已大大增强。美国已成为名副其实的世界经济“火车头”,在自身高速成长的同时,也刺激了全球经济的快速发展。 As we all know, the U.S. economy has been growing at an average annual rate of about 4% since the early 1990s and has miraculously lasted for nearly 10 years and has become the longest period of expansion in the U.S. economy. With the sustained and rapid economic growth, the U.S. economic strength has greatly increased. The United States has become a veritable “locomotive” of the world economy. While its own rapid growth, the United States has also stimulated the rapid development of the global economy.
