Common prosperity in the process of Chinese mode to modernization is both an essential requirement of socialism with Chinese characteristics and an important feature of Chinese mode to modernization. It is not a uniform egalitarianism， but a double affluence of material and spiritual lives. The promotion of common prosperity in the process of Chinese mode to modernization has confronted with realistic obstacles such as the need to raise overall level of people's affluence， the pronounced problem of unbalanced and insufficient development， the requirement to improve the system of distribution， and the lag in the development of common prosperity in spiritual life. Advancing common prosperity in the new era and on a new journey is a systematic project， which will be achieved through vigorously developing productive forces to realize high?quality economic development， through balancing the development between urban?rural areas and amongregions to narrow their development gap， through taking into account efficiency and equity to improve income distribution system， and through promoting cultural confidence and self?improvement to enrich the people's spiritual world.
