Abstract: At present,there are two indicators of China's urbanization level:the first is the urbanization rate of registered residents and the second is the urbanization rate of permanent residents.Between the permanent population and the registered population,there is a large group of migrant workers.The existence of dual urbanization rates originates from the urban-rural dual system and factor price scissors which depend on the primitive accumulation of capital.Through the design of this system,the cost of industrialization and urbanization is artificially reduced to accelerate China's industrialization and urbanization.Under the background of the oversupply of rural labor force,there is still room for the urbanization of this model.However,when the supply and demand of rural labor force comes to an inflexion point,urbanization of this model will be unsustainable and objectively it requires that a new type of "people-oriented" urbanization should replace the traditional one.In our country,the residence permit system for migrants has been implemented as a transitional measure of citizenship for the rural residents,or as a transitional measure to increase the urbanization rate of the registered population.However,for the migrants,the mode of maximizing their benefits is to retain both rural household registration and urban residence permit.This determines that the dual urbanization rates will exist for a long time.

Key words: dual urbanization rates, urbanization
