The deep integration of competitions and teaching is beneficial to the innovative capabilities of students and the teaching reform, so it is essential to build a competition-teaching integration model to explore the influences of the competition on the promotion of curriculum teaching, practical teaching, and faculty development. Firstly, based on the data from the National 3D Digital Innovation Design Competition (3D Competition), the participation data is analyzed by the current performance of students in 3D digital innovation design in terms of the quantity, quality, innovation points, and technological application of their works. Then, taking into account the curriculum system integration, teaching integration and faculty integration, a specific model for the integration of competitions and teaching is proposed to organically incorporate competition content, cases, and outcomes into the entire teaching process. Through the analysis of the outcomes in the advance of the innovative abilities of students, the teaching models, and the university-industry collaboration in Nanyang Institute of Technology, the practical measures and achievements in integrating the 3D Competition with teaching are illustrated in detail. This study provides theoretical support and practical references for universities to improve teaching and learning through competitions, and propel innovative talent cultivation and teaching reform.
