The teaching practice is based on leapfrog teaching theory, and through optimizing curriculum teaching, innovating subject competition mechanisms, and improving research guidance models, a collaborative development innovation ability training system is constructed. The teaching practice results of the applied undergraduate e-commerce major show that this model effectively enhances students'innovation ability, especially, students are able to in innovat in course teaching, subject competitions, and scientific research training, providing theoretical support and practical reference for the educational reform of applied undergraduate universities.
