Based on the microscopic survey data of the China Family Tracking Survey (CFPS), a combination of macro and micro analysis. The spatial characteristics of the distribution of young migrants are analyzed from the provincial level and the regional differences in the impact of migration on adult income were compared. The main conclusions include: 1) The overall distribution of the young migrant population is: the western region <the central region <the eastern region, with Shanghai, Liaoning and Guangdong provinces accounting for the highest proportion; 2) The young migrants continue to gather in the eastern region, and the proportion of distribution in the central region has been shrinking, and there is a "central collapse"; 3) Under the influence of human capital and social capital, only the migration to a "good" environment would have a positive effect on adult income.The return on human capital investment in the eastern region is 3.7 percentage points higher than that in the central and western regions;The return on human capital investment in urban areas is 2.9 percentage points higher than in rural areas.Through the mechanism analysis, it is found that the positive effect of juvenile migration on human capital is an important channel that affects adult income.
