Common prosperity is the essential requirement of socialism, a key feature of Chinese-style modernization, and a beautiful vision pursued by human society from generation to generation. Socialism with Chinese characteristics has entered a new era, and the CPC Central Committee with General Secretary Xi Jinping at its core has placed in a more important position the gradual realization of common prosperity of all the people, which has become one of the important matters of the country. To solidly promote common prosperity in the new era, first, we need to grasp its scientific connotations, that is, the unification of "whole" and "comprehensive" in terms of the subject and coverage of common prosperity, the unity of "head" and "pocket" with regard to the relation between material wealth and spiritual happiness, the unity of "shared together" and "jointly constructed" with reference to the process and result of common prosperity, and the unity of "do your best" and "do what you can" taking common prosperity as a long-term objective. Second, we should have an accurate understanding of the nature of common prosperity in the new era. Based on the common prosperity of Marxist theory and combined creatively with the characteristics of China’s practice and development in the new era, this concept is the essential requirement of socialism, the original mission of the communists, the fundamental guarantee of social harmony and the spiritual force of national rejuvenation. Finally, give full play to the "four forces" of market force, spiritual force, institutional force and moral force, and explore the diversified realization path of common prosperity in the new era. That is, to activate the vitality of market subjects, improve the market operation mechanism, form a comprehensive opening-up pattern, promote high-quality economic development with market force thus making the cake bigger, and common prosperity can be fully realized only on the basis of developed productivity. We should remain people-oriented, promote diligence and innovation, meet the reasonable needs of the people, always regard the people as the main subject of common prosperity for whom and by whom it is carried out, and constantly stimulate the people’s internal driving force with spiritual force to create prosperity and make the cake good. We should give full play to the advantages of the political system, economic and legal systems as they function, strengthen the regulation and enhance the accuracy of taxation, social security and payment transfer, expand the proportion of the middle-income group, adjust the income gap to a reasonable range, promote a scientific distribution system where those having gotten prosperous first help others to catch up, thus gradually realizing common prosperity, and use institutional forces to coordinate fairness and efficiency to let everyone share the cake. We should adhere to the principles of spontaneity and voluntariness and guide people to appreciate virtue and goodness, make balanced the micro flow of social resources and social wealth among different groups by means of fund-raising, donation and funding, encourage public charity and voluntary service with moral force, and let people embrace a sense of responsibility and dedication into their yearning for a better life, so as to make the realization of common prosperity in the new era a widely-shared moral practice.
