Abstract: Audit supervision promoting the Party's self-revolution is an innovative proposition in integrating Marxist party building theory with China's governance practice. At the theoretical level, audit supervision is rooted in the Marxist thought of power restriction and economic supervision, which embodies the inherent requirements of the proletarian party for the standardization of power operation and the compliance of economic behavior. At the historical level, audit supervision has gone through the stages of exploration in the New Democratic Revolution period, tortuous development in the socialist revolution and reconstruction period, reconstruction after the reform and opening up, and the comprehensive innovation in the new era, and has always resonated with the party's self-revolution process and accumulated rich governance experience. At the practical level, audit supervision is an urgent need to deal with the problem of corruption within the party, to improve governance efficiency, and to solve the unique problems of the big party. Audit supervision is not only an economic supervision tool, but also an important mechanism for the party to achieve self-purification and self-improvement under long-term ruling conditions, which highlights the political determination and governance wisdom of the Communist Party of China to promote self-revolution through institutionalization.

Key words: audit supervision, economic supervision, the party's self-revolution, governing the party strictly in an all-round way, intra-party supervision
