Measurement and Influence Analysis on Patent Quality Difference among Different Types of Collaborative Innovation:Taking China's Rare Earth Patents as an Example
Industry-university-research collaboration plays an important role in the national innovation system.The attention on whether there are differences in the quality of patents created by the four types of industry-university-re-search collaborative innovation is helpful to deepen the research on industry-university-research collaborative innovation.Taking rare earth industry innovation in China as an example,on the basis of reviewing the current patent quality evalua-tion literature,taking into account the use of continuous data and discrete data in patent quality evaluation information,this paper constructs a patent quality evaluation model of different collaborative innovation types of industry,university and research,and measures the differences of patent quality created by four types of collaborative innovation.The re-search shows that there are significant differences in the quality of patents created by different collaborative innovation types in China's rare earth industry,and the overall quality of industry-research collaborative patents is obviously higher than other combinations,followed by industry-university,university-research,and the lowest industry-university-re-search.Then the paper analyzes the possible causes of the difference from the theoretical and practical perspectives.
