Abstract

　　Based on a literature review, this article reveals the inconsistency in the ownership structure reform measures of on-duty inventions, a policy attempt to stimulate patent output and commercialization. It also proposes an analytical model to address the impact of intellectual property ownership structure on patent productivity. A total of 20 universities with two different kinds of intellectual property ownership structures in Sichuan Province of China are selected for this study. They are divided into two groups: “pilot group” and “control group”. The quantitative statistics and comparison of development trends and changes in the number, structure, technical fields, transfer and quality of invention patents are conducted, showing the development status of university patents before and after the ownership reform, and verifying the impact of the ownership structure of on-duty inventions on stimulating patent output. For a deep understanding of the situation, Southwest Jiaotong University is taken as a typical case for the study, which illustrates that after the implementation of the ownership reform, the number of disclosures of patent achievements of university on-duty inventions has increased, and the patent transformation in universities has undergone positive changes, but the positive changes in patent quality between universities are not obvious in the short term. In addition, this article puts forward countermeasures and suggestions for further optimization of the reform, with a view to achieve the staged evaluation of the reform and guiding practice. Finally, the article endeavors to provide academic peers with Chinese policy experiments and data regarding the impact of intellectual property ownership structure on invention output.
