作为一个综合实力最强的国家,美国并不是在建国时就是如此,其比较优势也经历了从自然资源产品向资本、技术密集型产品转变的过程,并在技术密集型产品的生产和出口上保持了较长时间的比较优势。美国相关的自然资源产品出口在经一次世界大战前后达到了高峰,在技术密集型产品方面的比较优势在20世纪50年代达到了高峰,直到20世纪90年代才呈现出了衰退的趋势。美国制造业的崛起和优势的保持与教育、技术、规模、管理水平和创新等多种因素有关。
As a country with the strongest comprehensive strength, the United States did not go through the process of its founding. Its comparative advantage has also undergone a process of transformation from a natural resource product to a capital-intensive and technology-intensive product. It has also been working on the production and export of technology-intensive products Maintain a comparative advantage for a long time. The exports of U.S.-related natural resource products peaked around World War I and their comparative advantages in technology-intensive products peaked in the 1950s and did not show a downtrend until the 1990s. The rise of the manufacturing industry in the United States and the maintenance of its advantages are related to various factors such as education, technology, scale, management level and innovation.
