Abstract: The exploration of transformation from intellectual property management to intellectual property governance is not only the demand traction in the practice of China's intellectual property system, but also the bottleneck to be broken in the theory of intellectual property governance. From the perspective of process management, this study divides intellectual property governance into four links: creation, application, protection and service. Through policy text and multi-case grounded analysis, the interaction mechanism of intellectual property governance subjects in each link is explored. The results show that the creation, application, protection and service of intellectual property governance are not isolated, but interrelated and nested, and there are significant differences in the functional positioning and interaction of intellectual property governance subjects in different links, and the heterogeneity is dynamic.
