近10年来,虽然全世界对商品及劳务的需求呈爆炸性增长,但是美国主要的出口项目,除了排名顺序略作更动外,基本上并无改变。专家预测,美国仍将凭借科技领先优势在国际市场上与其他国家竞争,因此,未来其出口主力仍将保持不变。 1986年,飞机、数据处理机、汽车零件和高科技机械是美国主要的出口项目,迄今也仍是如此。 In the past 10 years, although the demand for goods and services in the world has exploded, the major export items in the United States have basically remained unchanged except for a slight order-of-order change. Experts predict that the United States will still compete with other countries on the international market by virtue of its scientific and technological advantages. Therefore, its main export will remain unchanged in the future. In 1986, aircraft, data-processing machines, auto parts and high-tech machinery were the major U.S. exports and have so far been.
