Giving full play to the role of the third distribution in promoting the building of a uncorrupted society is an important issue clearly put forward at the 19th National Congress of the Communist Party of China to promote social fairness， efficiency， and common prosperity. Clarifying the role and boundaries of the third distribution on China''s integrity culture and mechanism and building a new era of integrity culture system will become driving force to promote the high-quality development of China''s economy. Therefore， it is particularly urgent to examine the state of integrity culture research as a whole and to grasp its doctrinal orientation. First， at the theoretical foundation level， we should discuss the overall construction of the theory of integrity culture and clarify questions of why and how the integrity culture system is built. Secondly， at the level of system construction， it is necessary to clarify the operation mechanism of the integrity culture， for instance， who the main body is， what the tasks are， and what forms and functions are in the integrity culture mechanism. Finally， at the level of practical development， it is necessary to emphasize the role of the third distribution to empower the theory and mechanism of integrity culture and to realize the transition from academic theory to practice in research on integrity culture theory and mechanism.
