How to explain the changes in the pattern of international trade division after the war?

Great changes have taken place in the division of international trade after the war, which are embodied in the following aspects:

1, the degree of internationalization of production has been greatly improved, and the great productivity released by the modern scientific and technological revolution has made scientific and technological development and production progress increasingly international;

2. The large-scale internationalization of industrial capital and the rise of multinational corporations have made the division of labor within enterprises and departments develop into international specialization;

3. The traditional international division of labor based on natural resources has developed into a new international division of labor based on product specialization, parts specialization and process specialization;

4. The disintegration of the old colonial system has also changed the pattern of international division of labor to some extent, and developing countries are increasingly participating in the world industrial division of labor system.
