There are practical difficulties in the integration of industry and education in higher vocational education, such as data silos and lack of credit, inefficient resource sharing and property rights disputes, and lack of collaborative education mechanisms between schools and enterprises. Blockchain technology can provide ideas and paths for the integration of industry and education in higher vocational education to a certain extent. This study uses case analysis and interview methods to construct a four level and five module integration model. Based on four case studies, it proposes a three-stage evolution path of blockchain technology through infrastructure construction, application deepening, and ecological maturity, as well as three key innovation paths of institutional innovation, technological integration, and ecological cultivation, to promote the reform of industry and education integration. Research has shown that during the infrastructure construction period, the construction of an alliance chain network for government supervision, vocational colleges, enterprises, and third-party certification nodes should be completed; The rate of data on student training records, enterprise resource investment, and other data being stored on the blockchain is 92%; Develop ten standard contract templates for credit mutual recognition, equipment sharing, etc., and improve the efficiency of signing school enterprise agreements by 58%. In the future, it is necessary to further deepen the application of blockchain technology, improve cross chain standards, privacy computing and other technological adaptations, and promote the formation of a self-driven industry education integration ecosystem.
