The new-generation Rural workers are main part of urbanization. But because of the omissions in the adjustment of the social structure, the new-generation rural workers have to work in big cities, while their children are educated in small and medium-sized cities and their parents live in the countryside. We name this phenomenon "the new ternary structure" in the process of urbanization. In order to resolve the new social contradictions and achieve the harmonious development of society, the government should face up to the unfavourable situation of the new-generation Rural workers and respect he new-generation migrant workers' will. Especially, the government should reform the police of urbanization and develop the small and medium-sized cities' function in absorbing the floating population. <<
