In the context of graduate education reform, cultivating high-level professional degree graduates through industry-education integration has become a key task for the future development of "Double First-Class" universities. Drawing on the French engineer training system, this paper constructs a 6.5-year Sino-French industry-education integration training framework that includes cognitive internships, research internships, and engineer internships. It analyzes the elite training philosophy and distinctive advantages of this model. The study finds that the model aims to cultivate compound talents with an international perspective and innovative capabilities by deeply integrating educational resources with industry demands. Empirical research shows that the model effectively promotes the synchronous improvement of students' theoretical and practical abilities, enhances their occupational adaptability and innovation capabilities, and has a positive impact on the bidirectional development of Sino-French higher education. The paper also analyzes the implementation effects of the Sino-French cooperative industry-education integration training model and proposes optimization suggestions to address current challenges, aiming to improve the quality and efficiency of the training model. The research results provide theoretical and practical references for the innovation of industry-education integration training models in "Double First-Class" universities and offer valuable insights for the reform of professional degree graduate education.
