In the context of building a strong education country and global industrial reform, the graduation thesis of engineering and technology professional degree faces a “triple disconnect” between quality and ability, industry demand and international standards, which restricts the improvement of international competitiveness of talents.This study aims to explore the transmission mechanism of “thesis quality-core competence-international competitiveness”, and construct a three-dimensional linkage model of “goal anchoring-path embedding-cooperative guarantee” for “quality and ability” double improvement by using literature research, questionnaire and enterprise interview.This model is oriented to international competitiveness, reconstructing the three-dimensional quality goal of “academic standard-practical innovation-international adaptation” and the four-dimensional ability goal system of “engineering practice”, with supporting core modules such as dual-cabinet topic selection, three-module embedding, collaborative guidance and three-party evaluation.The practice of related majors in Tianjin Polytechnic University shows that the topic selection of the pilot group is 85.7% related to the needs of enterprises/international, the average score of core competence increases by 27.9%, and the application rate of international standards increases by 31.4%.The study proves that this model can effectively solve the traditional dilemma, and the three-way collaboration between “university, enterprise and international organization” is the key, which can provide a practical plan for the international competitiveness of engineering and technology professional degree talents.
