In the past, the U. S. manufacturing industry exported a large number of high value-added small items and outsourced low-value-added products and assemblies to other countries. Now this situation has undergone some reversals, and some companies have made some bulky due to logistics considerations. The assembly of low-value products is rearranged domestically, while the production of high-value parts is still arranged overseas. Nevertheless, from a global perspective, the comparative advantages of emerging countries are still obvious, and the development potential of the manufacturing industry still exists. Trade theory shows that once a country has an advantage in a certain industry or product, this advantage will be strengthened due to factors such as increasing returns to scale and incomplete competition. Therefore, after decades of manufacturing transfer, China And other emerging countries' advantages in manufacturing have been formed, which is a great challenge to the return of American manufacturing. This text mainly introduces:. ['U. S. manufacturing recovery has a huge impact on emerging countries.', 'Increasing science and technology content and added value are conducive to the development of manufacturing.', 'Changes in the international division of labor system provide opportunities for the return of U. S. manufacturing.', 'U. S. manufacturing does not have comprehensive advantages in competing with emerging markets.']
