The comprehensive advancement of the policy of vocational college upgrading to undergraduate education has brought new development opportunities for talent cultivation of the Engineering Management major, and put forward higher requirements for the teaching connection between vocational college and undergraduate stages. As the core carrier for cultivating application-oriented talents, the integrated quality of practical teaching directly affects the effectiveness of talent cultivation. Centered on the orientation of "improving from vocational college skills to undergraduate comprehensive competence", this paper first analyzes the policy requirements and practical significance of integrated practical teaching for the Engineering Management major under the background of vocational college upgrading to undergraduate education. Secondly, through investigation and research, it sorts out core problems such as disjointed connection, vague objectives, repetitive content, and scattered resources existing in current integrated practical teaching. Finally, from five dimensions including objective system reconstruction, content module optimization, teaching mode innovation, resource platform co-construction and evaluation mechanism improvement, this paper constructs an integrated practical teaching path, and puts forward feasible solutions for the connection of practical teaching of the Engineering major in the transition from vocational college to undergraduate education, so as to cultivate compound engineering management talents meeting industrial demands.
