The current research on solving major urbanization problems based on a single dimension has limitations. To break the current mindset of urbanization that focuses on “urbanization based on urbanization, industry based on industry, space based on space, and governance based on governance”, and promote a new type of urbanization with the people centered systematically concept, the overall idea is to focus on one core, establish two overall situations, clarify three relationships, and coordinate four dimensions. Putting people at the core is the essential requirement for improving the quality of new urbanization. The strategic overall vision of the great rejuvenation of the Chinese nation and the unprecedented changes in the world are the basic starting points for promoting high-quality construction of new urbanization. Grasping the relationship between short-term and medium term, fairness and efficiency, new urbanization and new industrialization, and comprehensive rural revitalization is an important guarantee for improving the quality of urbanization. Achieving the matching of population, industry, space, and governance in the four dimensions is the key to improving the quality of new urbanization under the system concept.
