Strengthening Party selfgovernance strictly of marxism theory has experienced a historical evolution and contemporary innovation, from “Party building”, “Party selfgoverning” to “strengthening Party selfgovernance strictly in every respect”.In Marxs works, there are rich Party governance theories of the Communist Party, and Lenin carried out the ruling Party theory of the Russian Communist Party (Bolshevik Party) in the Soviet revolution. Combining the actual conditions of China, Mao Zedong explored leadership theory of the Communist Party initially. After the reform and opening up, Deng Xiaoping, Jiang Zemin and Hu Jintao deepened and pushed forward the “strengthening Party selfgovernance strictly” constantly, according to different historical tasks of the Party in different times. After the 18th national congress of the communist party of China (CPC), Xi Jinping put forward the theory of “strengthening Party selfgovernance in every respect” decisively. The 19th National Congress of the Communist Party of China, has proposed to build a Party system of “one commander”, “one mainline”, “two wings” and “one bottom line”, which enriched and developed the Marxism Party theory.
