University-enterprise (U-E) innovation chain fractures hinder the commercialisation of knowledge. However, few contributions in the academic field have uncovered how certain mechanisms repair U-E innovation fractures and commercialise their research results. In order to bridge the research gap in the repair mechanism of U-E innovation chain fractures, a multiple-case study of U-E innovation fractures was conducted by proposing a ‘behaviour-process-outcomes’ repair model. The results are as follows: motivation coordination mechanism is the driving force that converges the goals of different organisations; organisation coordination mechanism is the platform that provides the basic support for the weak links and makes up for the defects of a single organisation; capability development and coordination is the element of U-E cooperation through a combination of basic and applied research capability, technological innovation capability and product commercialisation capability; policy coordination mechanism is the vehicle of U-E innovation chain that strengthens U-E cooperation with various preferential policies. The conclusion shows the ‘coordinated innovation’ repair model for U-E innovation chain fractures provides important insights for practitioners and policymakers involved in developing an innovation chain in U-E cooperation.
