Under the wave of the digital economy, technological fission and industrial reconstruction have forced vocational education to break through the dual fragmentation of "education - industry", and its reform effectiveness has become a key variable in the competition for national technological sovereignty and the guarantee of industrial security. This article focuses on three major propositions: the collaborative breakthrough of "technology - talent", the reengineering of social mobility mechanisms, and the reconstruction of global industrial chain rules. It proposes a reform path targeted at "the integration of the four chains" : By building a digital twin platform of "dynamic perception of industrial demand - real-time response of educational supply", it breaks the information cocoon and cognitive lag between schools and enterprises. Taking the "industry college" as the fulcrum, embedding the real R&D scenarios and production processes of enterprises, a symbiotic mechanism is formed where "technological iteration drives course evolution and teaching scenarios feed back to process innovation". Innovate the mutual recognition system of "dual positions and three roles" (teacher - engineer - technology broker), and open up the transformation channel between the accumulation of technical skills and industrial innovation; Establish a three-dimensional evaluation system of "technology contribution rate + job competence + social service efficiency", and promote vocational education to shift from "talent matching" to "value symbiosis". The "multi-party co-governance" model of China's integration of industry and education is exporting Chinese standards through carriers such as the "Lu Ban Workshop", providing a new paradigm of "education chain - industrial chain" co-evolution for the modernization of global vocational education.
