Abstract: Academia has been paying attention to the issue of the leading core of the Communist Party of China for a long time.They have reached a consensus on what is the core of the party's leadership and how to play a central role.But the historic origin of this issue,substantial issues,such as the position and formation mechanism of the leading core in the organization system of proletarian party are rarely addressed.In the history of international communist movement,whether a strong leadership core can be formed or not is a sign of the maturity of a proletarian party.It not only needs some subjective and objective conditions,but also should be based on a stable leadership group.In addition,important time nodes and crucial historical juncture are also important conditions for the formation of the leadership core.In the history of the Chinese Communist Party,there are three main modes of generating a leadership core.One of these is through the test of long-term revolutionary struggle,naturally forming the pattern of the central collective leadership core.Secondly,it is proposed by the previous generation of the central leadership core,and later recognized by the party's central plenary as the core model of leadership.Thirdly,elected the National Party Congress,and then confirmed by the Central Plenary Session of the Party as the core model of leadership.This system design was initiated by Mao Ze-dong and gradually established by Deng Xiaoping's concentrated discussion.This is a great pioneering work in the history of the development of Marxist political parties.It has perfected the top-level design of the party's democratic centralism and strengthened the last link of the smooth operation of this system.

Key words: Communist Party of China, the Collective of the Party Central Committee, the Leading Core
