The impact of intergenerational income mobility on internal migration in China

This study examines the impact of income mobility on internal migration across prefectures in China. We use income intergenerational persistence to evaluate income mobility and find that migrants prefer cities with higher income mobility. We further use the instrumental variable estimation and a set of robustness tests to verify the reliability of our findings. The influence is larger among women, the elderly, and the less-educated, while the economic prosperity of destinations could relatively offset the negative effect of lower income mobility on migration. Additionally, higher mobility not only attracts but also retains migrants, hence benefiting the local economy. Through further exploration, we find that the real migration influencing factor underlying the higher income mobility is the higher job mobility, indicating that the real pursuit of Chinese migrants is the increased access to suitable job opportunities.
