Cultural influence of population migration

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 very 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, the high-quality labor created by a large amount of training fees is undoubtedly used by foreign countries, which is the biggest loss.

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.
