The influence of world population migration

After the war, the phenomenon of international population migration changed from capitalist countries to backward colonies to poor countries to rich countries, which had different effects on developed countries and developing China countries.

Because the population growth is slow. For developed countries with a serious aging population, immigrants make up for the shortage of their labor force. Immigrants with specialized skills not only bring scientific knowledge and production technology from other countries, but also save education expenses for immigrant countries. For developing countries whose population growth rate is still high, although the emigration of population has eased the pressure on their own population, because these people are not ordinary laborers, but scientific and technological personnel, professionals and talents, a large number of high-quality laborers created by training fees are used abroad, which is undoubtedly the biggest loss for developing countries.

With the development of large industries, economic growth no longer depends mainly on the expansion of labor-intensive industries, and science and technology become the primary productive force. International competition is the competition of talents in a specific environment. Therefore, how to stop the phenomenon of "brain drain" in developing countries caused by various factors is the main problem in the current international population migration research.
