To achieve the goal of common prosperity for all people, we must better address the imbalance and inadequacy of China's economic and social development in the new era, improve the basic public service system, improve the level of public services, enhance the balance and accessibility, and effectively promote the common prosperity of all people through high-quality development to achieve more significant substantive progress. The exploration of the theory and practice of common prosperity under the leadership of the Party and the people has been expanding with the changes in China's development stage and major social contradictions. The Party led the people to win the great victory of the new democratic revolution, providing the basic social conditions for common prosperity; The socialist revolution and the promotion of socialist construction have laid the fundamental political premise and institutional foundation for common prosperity; Reform and opening up and the socialist modernization drive have provided institutional guarantees and material conditions for common prosperity. Since the 18th National Congress of the Communist Party of China, socialism with Chinese characteristics has entered a new era. The Party has led the people to win the battle against poverty and build a moderately prosperous society in an all-round way. More tangible and substantial progress has been made for the common prosperity of all people, and we have taken the momentum to enter a new development stage of building a socialist modern country in an all-round way and marching towards the second century goal. To firmly promote common prosperity in the new development stage, we must base ourselves on the new situation of unprecedented changes in the world and the transformation of major social contradictions in China, implement the new development concept, build a new development pattern, and take the road of high-quality development. In the new stage of development, solid efforts to promote common prosperity will inevitably require high-quality development. On the one hand, the problem of unbalanced and insufficient development is the main factor affecting common prosperity at present. To achieve balanced regional, urban and rural development and improve the overall level of economic development, it is no longer feasible to make the "cake" bigger only by relying on high-speed growth. It is also necessary to improve the quality through high-quality development, and achieve sustainable growth in quantity through substantial improvement in quality; On the other hand, the people's yearning for a better life is diversified, multi-level and multifaceted. The people are most concerned about whether the most direct and realistic interests are "good or not" from the single dimensional material aspect in the past to the multi-dimensional "good or bad" of democracy, rule of law, fairness, justice, security, and environment. Only by implementing the new development concept, realizing high-quality development with innovation as the first driving force, coordination as an endogenous feature, green as a universal form, openness as the only way, and sharing as the fundamental purpose, can people feel more secure, happy, and secure. The report of the 20th CPC National Congress pointed out that common prosperity is the essential requirement of socialism with Chinese characteristics, and it is also a long-term historical process. Achieving common prosperity is complex and arduous. We must ensure and improve people's livelihood in the process of development. First, we should fully understand that common prosperity is a long-term goal and should be achieved in the organic unity of productivity development and production relations reform. To promote common prosperity in high-quality development is actually to constantly push forward in solving major social contradictions
