County-level cities are important carriers for absorbing rural popul-ationswho will be transferred and are the main positions for advancing new urbaniz-ation. Enhancing the comprehensive carrying capacity of county-level cities is of great significance to promoting the development of new urbanization with high quality，promoting the coordinated development of urban and rural areas，and satisfying people's needs for a better life. At present，the comprehensive carrying capacity of Henan's county-level cities has steadily increased，but there is a big gap compared to the average level of the country，the province，and the big cities，and there are many factors such as industry，infrastructure，public services，and the ecological environment that constrain its further improvement. In the future，Henan must deepen its reforms，proceed with planning，industry development，urban construction，ecological governance，and institutional and institutional innovation，and take comprehensive and effective measures to accelerate the improvement of comprehensive carrying capacity of county-level cities.
