The rural youth in developed areas have achieved local urbanization by taking advantage of their location and industrial and commercial development. However, those in the Pearl River Delta and the Yangtze River Delta have different attitudes and behaviors in career choices due to differences in land benefit distribution methods, labor concepts, urbanization paths, and protective forces. Rural youth in the Pearl River Delta are more inclined to choose Low-end jobs, and value leisure over work; Rural youth in the Yangtze River Delta are more proactive in choosing careers, focusing on family resource accumulation and class jumps. The difference in career choices determines whether rural youth can establish an organic connection with the urban economic, social and cultural system. This has also become an important factor affecting the level of citizenship of rural youth in the Pearl River Delta and the Yangtze River Delta. The realization of a higher level of urbanization requires rural youth to give play to their human capital advantages, choose highly competitive careers, and accumulate real citizenship capabilities.
