The report of the 20th National Congress of the Communist Party of China (CPC) pointed out that we should promote a new type of urbanization centered on people and accelerate the urbanization of agricultural transfer population. Urbanization is the only way to modernization. The primary task of new-type urbanization is to promote the citizenization of agricultural transfer population, which is an important link to promote China's more than 1.4 billion population into a modern society as a whole and realize Chinese path to modernization with a huge population. It needs to combine the basic national conditions and development approaches, adhere to the principle of seeking progress while maintaining stability, step by step, and continue to advance. Currently, the urbanization rate of China's permanent population has reached 65.2%. As urbanization enters the mid and late stages, China is ushering in an era of urban-rural integration and development. The county located at the "end of the city and the head of the township" has become an important carrier for coordinating the promotion of new urbanization and rural revitalization, and achieving common prosperity for all people. From the introduction of the first central level policy document on county urbanization in May last year, to the report of the 20th National Congress of the Communist Party of China, which clearly stated "promoting urbanization construction with county as an important carrier", Then this year, the No. 1 central document and the Government Work Report respectively emphasized that "we should further promote the citizenization of rural migrant workers in the county, establish and improve the mechanism that basic public services are linked to the permanent population and supplied by the permanent residence", "improve the functions of cities, especially county seats, and enhance the comprehensive carrying capacity". The strategic fulcrum role of the county is increasingly prominent, and high-quality promotion of the citizenization of agricultural transfer population in the county is imperative. County urbanization does not mean limiting the process of urbanization in large cities, but rather rational division of labor and coordinated development in the urbanization pattern. County citizenship requires efforts to address weaknesses in health care, basic education, municipal facilities, human settlements, and employment quality, so as to promote the ability of agricultural migrants to "settle down" and enjoy basic public services in the county to accumulate health capital, "strengthen" and continue to receive diversified training to accumulate intellectual capital, "integrate" and deeply participate in social governance to accumulate social capital, It can not only achieve spatial mobility from rural areas to cities, but also achieve social mobility from marginalized to middle-income people. Optimize the financial transfer mechanism and improve public services and infrastructure construction in county towns. Providing high-quality public services is an inevitable requirement to meet the needs of the people for a better life. To achieve the equalization of basic public services in various regions, the role of fiscal and tax mechanisms should be fully played. First of all, by increasing the financial transfer and payment efforts to county-level cities, achieve consistency between financial and administrative powers within the county. On this basis, we will improve the public health system, expand the supply of basic education resources, develop elderly care and childcare services, and optimize cultural, sports, and social welfare facilities. At the same time, it is necessary to improve municipal public facilities and improve the quality of human settlements. The improvement of the hardware base is conducive to enhancing the carrying capacity and attractiveness of the population, as well as "building nests to attract phoenix", attracting talents, promoting investment attraction, and promoting regional development. Consolidate the industrial foundation of the county seat and enhance the human capital accumulation of the agricultural transfer population. Industrial support and sustainable employment are the foundation and prerequisite for the citizenization of agricultural transfer populations, which can enhance their ability to integrate into cities and accelerate the process of new urbanization. First, it is necessary to fully tap the industrial potential, enhance industrial support capabilities, and create rich entrepreneurial employment opportunities. The second is to improve the construction of industrial supporting facilities, in order to reduce enterprise production costs and
