From the perspective of the process of urbanization, this paper puts forward the corresponding public policy control by analyzing the characteristics of "hollowing" at different stages of urbanization. Moreover, the paper focuses on the stage of China's current urbanization. Based on the survey of migrant workers, this paper evaluates China's current policies, and argues that the rural "hollowing" is an objective that accompanies urbanization. At different stages of the process of urbanization, the rural "hollowing" presents different characteristics. Local governments should make policy and plan based on the different stages of local urbanization and local conditions, because of the extent of regional differences in economic and social development. This paper aims to guide the rural "hollowing" to develop toward the right direction.
