China's high-quality economic and social development during the period of the 14th Five-Year Plan is of great significance and has far-reaching implications for consolidating the achievements made in completing the process of building a well-off society in an all-round way and basically realizing socialist modernization. However, many uncertain and unstable factors, such as the suppression of western countries, the weakness of the global economy, the profound impact of the epidemic, and the adverse trend of globalization, are likely to continue in the 14th Five-year Plan. It can be predicted that in such a severe and complex environment, it will be more difficult to achieve the above stated goals. This has raised higher requirements and placed more expectations on how to promote high-quality development during the period of the 14th Five-year Plan.This paper takes how to promote the high-quality development in the 14th Five-year Plan of China as the problem orientation and foothold. An analytical framework of the driving force system is constructed on the basis of defining the development environment at home and abroad and grasping various soft and hard constraints faced by the development. In order to achieve high-quality development in economic and social development during the period of the 14th Five-Year Plan, China owns three major factors that are crucial: the driving force of development, the carrier of development, and the guarantee of development. Among them, the driving force of development is new urbanization, digitalization and industrialization. The carrier of development is urban agglomeration, industrial agglomeration and world-class urban agglomeration. The guarantee of development is emancipation of the mind, opening up to the outside world and release of essential factors.
