Abstract: From the perspective of regional differences, based on the practice of farmers' county urbanization in the developed coastal areas in the east and the generally agricultural areas in the central and western regions, the article constructs the practice type of farmers' county urbanization, so as to try to enrich and expand the existing research on county urbanization. The study found that, due to the different industrial bases, the rural urbanization practice of farmers in the eastern developed areas and that in the underdeveloped areas in the central and western regions showed two patterns: "endogenous urbanization" and "exogenous urbanization". The "endogenous urbanization" formed by the farmers in the eastern developed areas relying on the development of local industrialization shows the practical characteristics of non-agricultural family labor allocation, urban and rural spatial span without leaving their hometown, and the urban-rural resource flow pattern of industry feeding agriculture back. It is a stable and sustainable complete urbanization model. The underdeveloped areas in the central and western regions have a weak industrial foundation within the county. The "exogenous urbanization" formed mainly by relying on the input of resources from external big cities shows the characteristics of labor allocation of semi industry and semi farming, urban and rural spatial span of leaving the land and hometown, and the practice of two-way concentration of urban and rural resources to the county seat. It is a semi-urbanization model with instability and high risk. In order to further promote the stable and high-quality development of county urbanization, the corresponding policies are formulated with the core of "farmers can live a stable life in the city", so as to promote the gradual transformation of farmers' production and lifestyle to the urban system.
