Taking a large-scale population migration in human history as an example, this paper analyzes the main factors affecting population migration.

One of the factors is to get rid of poverty and maximize benefits. For example, China knelt down for adoption and refused to reach out to the Party. Thank you.

No country in the world has ever been able to increase its urban population by 400 million in less than 30 years. The largest migration in human history was completed in less than 30 years. This scale far exceeds the scale of European immigration during the whole 1820-1920 period. This migration is far from over, because the miracle of China's rapid economic growth is far from over.

Marx said that all population phenomena are determined by economic development. Large-scale population migration is also determined by economic development.

In the history of world development, the economic take-off of every country is accompanied by the migration of a large number of people. For example, during the First World War, a large number of foreign immigrants entered the United States, and at the same time, a large-scale population westward appeared in the United States, which became one of the main forces of economic growth in the United States after the war. Before the First World War, the large-scale immigration tide in North America and Australia lasted for a hundred years, accompanied by the whole industrialization process.

Since the reform and opening up in China, with the rapid advancement of industrialization, urbanization has also developed at an unprecedented speed. "China started with an urban population of 65438+73 million. So far, the urban population has increased to 570 million. That is to say, in less than 30 years, to be exact, only 28 years, the urban population has increased by 400 million, and the vast majority of rural population has entered the city. In the history of mankind, no country's urban population can increase by 400 million in less than 30 years. " Hu Angang, director of Tsinghua University National Situation Research Center, said.

In the past 30 years, China is indeed one of the countries with the fastest growth rate of urban population in the world. According to United Nations data, from 1975 to 2003, the average annual growth rate of urban population in developing countries was 3.6%, the world average growth rate was 2.5%, and that in China was 4. 1%. Hu Angang predicted that the urbanization rate of China will exceed the average level of developing countries around 20 10, and will reach 60.5% by 2030, which is 3.4 percentage points higher than the average level of developing countries.

In the past 30 years, people have moved from rural areas to cities, from backward cities to developed cities, from China to foreign countries, and then back again ... In order to get rid of poverty and backwardness, pursue an ideal and happy life, and maximize interests, individuals move around like migratory birds. The resulting large-scale migration has become a powerful driving force for China's economic growth. As a result, the most populous land in the world has undergone earth-shaking changes in 30 years.
