Facing the structural mismatch between school training and enterprise demand in vocational education, the study reveals the deep-seated blocking mechanism of industry-education docking in the context of supply-demand mismatch and explores its cracking path. Starting from institutional analysis, the study clarifies the multi-stakeholder interactions among the government, schools and enterprises. Then, through extensive research for institutions, enterprises and graduates, 18 specific influencing factors are measured under the four dimensions of supply-side, demand-side, mutual coupling and government environment. On this basis, a progressive analysis strategy of structural analysis-multiple regression-structural equation modeling was designed to test the mechanism of the influencing factors of industry-education docking. Factors such as benefit distribution (centrality degree 5.245), policy support (influence degree 3.045), and technical talent demand (cause degree 1.517) reside in the key position of the network. Multiple regression further confirms that benefit distribution, enterprise participation willingness and policy support are the most significant influence variables on docking effectiveness, with standard regression coefficients β of 0.201, 0.174 and 0.190, respectively. Through the full path analysis of structural equation modeling, the coupling mechanism between two parties has the strongest direct effect on the effectiveness of industry-teaching docking, with a path coefficient = 0.657, and it acts as a key intermediary bridge, and the policy environment then by influencing the coupling mechanism, path coefficient = 0.688.
