Abstract: The fifth plenary session of the 19th Central Committee of the Communist Party of China explicitly proposed to establish a new development paradigm featuring dual circulation，in which domestic and overseas markets reinforce each other，with the domestic market as the mainstay This new development paradigm is consistent with the internal logic of the circulation of the national economy as revealed in Das Kapital Viewed from the perspective of Das Kapital，the inherent mechanism of how the digital economy empowers the new development paradigm is manifested in the following three aspects At the level of individual capital，the digital economy promotes the circulation continuity by expediting the transformation of capital's form，and improves the turnover efficiency by reducing the circulation cost，shortening the time consumption，and innovating the fixed capital compensation mode At the level of total social capital，it facilitates the formation of a strong domestic market and provides highquality product and technology supply by promoting the value compensation and physical compensation of total capital It also provides a strong driving force for the circulation of total capital by enhancing the intermediary role of currency At the level of international circulation，the digital economy can deepen the world market connection，strengthen the international law of value，reshape the pattern of the international division of labor，help domestic and overseas markets reinforce each other，and promote the final formation of the new development paradigm featuring “double circulation”.
