Abstract: "Common prosperity in sport" is a practical concept embedded in the new development stage of Chinese-style modernization. This study tries to sort out and construct its internal logic from multiple dimensions, which is an academic necessity to grasp its generating law and guide its development trend. From the conceptual logic perspective, it will be weak if adopted by conjunctive and disjunctive interpretation, while relational interpretation can define it more scientifically. From the perspective of the theoretical logic, common prosperity in sport is the development of historical materialism in the historical stage of socialism with Chinese characteristics. It criticizes the " alienation in sport" and "polarization" under the capital logic. With "labor" as the core category, the theoretical framework is constructed in the subject and object relationship between sport and wealth, and a brand-new theoretical development is obtained in the contemporary era. In terms of practical logic, only by adhering to the leadership of the Party, improving the basic public service for sport, revitalizing the sport assets and fairly distributing them, will the common prosperity be achieved and the "essential return" of sport be promoted. From the logic of value, the common prosperity in sport makes the distribution of sports justice more prominent, which is the vivid footnote of the new form of human civilization, also the realistic beginning of the "two reconciliation".
