Abstract: Maintaining the Communist Party members' vanguard nature all the time is the premise and the foundation on which our party is in power for long time.We must profoundly know that constructing persistent effect mechanism is the critical strategy reflection on our party' s vanguard building and another new significant project that the Central Party Committee continues to advance the building of the party.If we want to construct the persistent effect mechanism of maintaining the Communist Party members' vanguard nature,we must establish the training mechanism for Party members,perfect the goal management mechanism and the right guarantee mechanism for Party members,establish the encouraging as well as punishing mechanism and improve the mechanism of exhaling the old and inhaling new and the internal and external supervising mechanism for Party members.
