2. Low income level: If the income level in this area is lower than that in other areas, it may lead to population mobility. People may choose to find a better life instead of staying in a low-income place.
3. Environmental quality: The environmental problems in Beijing-Tianjin-Hebei region have attracted much attention for a long time. If the environmental quality is too poor, population migration may occur. If the environment in a certain area is too bad, people will not want to live here.
4. Population aging: If the population of a region is seriously aging, it may lead to population mobility. The small inflow of young people and the large outflow of old people may represent social problems in this regard.
5. High housing prices: Beijing-Tianjin-Hebei housing prices have remained high. Excessive housing prices will make it difficult for young people to buy a house and the burden of buying a house is heavy. In the long run, it may lead to the loss of some young people.
6. Population outflow and agglomeration effect: From the national level, in order to improve the uneven distribution of population agglomeration, China has implemented the strategy of "coordinated development of Beijing, Tianjin and Hebei" in the past few years. In view of the existing problems in Beijing-Tianjin-Hebei region, a large number of parks and industrial clusters began to land. The landing of these new businesses has attracted some foreign people to Hebei, Henan, Shandong and other places, and has also had a certain impact on the willingness of some local residents to buy houses.
