Strengthening the cultivation of practical innovation ability of the talents majoring in engineering discipline becomes the key to engineering talent cultivation under new engineering background. Aiming at the problems in the cultivation of practical innovation ability majoring in package engineering， this paper studies and sets up the leading-style ability cultivation model by “three-integration and three-driving” based on students’ subject contest， constructs and expounds the connotation of this cultivation model， and proposes practical countermeasures in such three perspectives as reforming major theory and practical teaching by taking the knowledge contents of subject contest as key point， deepening the “integration between production and teaching” by taking each level subject contest as media， and reforming management model of teaching organizations by taking effective development of subject contest as the foundation.
