Discipline competition plays an important role in the training program of architecture graduate students. Exploring how to play the positive role of discipline competition is of great value for improving the training quality of architecture graduate students. This paper summarizes and analyzes the influence of discipline competition on the training of graduate students, explores the role of discipline competition in the training of graduate students in architecture from five aspects, such as problem awareness, innovative thinking, team spirit, discipline integration and cutting-edge knowledge, and then elaborates how discipline competition can improve the ability of graduate students in various aspects by combining related competitions in architecture disciplines as cases. It also proposes the training plan and ideas for optimizing the integration of competition and practice for architecture graduate students, including the establishment of the course system combining competition and training, the improvement of the competition counseling and support mechanism, and the development of continuous evaluation and improvement plans and other relevant measures, hoping to improve the comprehensive ability of combining practice and innovation for architecture graduate students through the integration of competition and practice.
