With the advancement of urbanization, the imbalance in the spatial distribution of China's urban and rural population has increased. Research reports show that the actual population density of China's big cities is far higher than that of Tokyo and New York. In contrast to the "overload" situation of big cities, the phenomenon of population loss and poverty is becoming more and more serious in small cities, towns and villages in China. More and more people begin to reflect on the development path of China's urbanization. The high urbanization rate caused by the urbanization of small towns and small towns is quite common in developed countries in Europe and the United States, which provides us with a reference for the implementation of urban-rural integration and new urbanization. We can make full use of the time and distance dividends brought by high-speed rail and the characteristics of the age of remote office in network society, optimize the industrial layout and spatial layout of population in big cities and small towns, and let more of the incremental population brought about by the increase in the "urbanization rate" flow to small cities and towns. It has become a consensus among policy makers and scholars to reasonably control the population density and scale of big cities and accelerate the development of small towns to improve the new urbanization. In the proposal of China's 14th five-year development plan and the long-range goals for 2035, the main content of promoting new urbanization is to "coordinate urban planning, construction and management, reasonably determine urban scale, population density and spatial structure, and pursue more balanced development of small, medium, and large cities, and small towns".
