My International Project at RIETI has been a great life experience. In the five months of my work there a great push to finish my doctoral research has been accomplished. If I did not participate in this internship at RIETI, I might not have the chance to access the Researchmap dataset, and study their data processing techniques. Moreover, I might also not have the chance to learn the data processing insights from other excellent researchers at RIETI. During the project, I also had the great opportunity of attending a workshop at MEXT. I attended as a member of RIETI group and shared my experience of data processing techniques together with my research ideas with professors and students from other groups.
My international project at RIETI was entitled “Empirical Analysis of Japanese Open Innovation”. My job was to conduct a comparative analysis of Japan and China’s innovation ecosystems by focusing on university–industry collaboration activities. In more detail, such research included three parts: (1) Construction of network indicators of Japan and China’s university-industry co-application patents. Analysis and comparison of the evolution patterns in Japan and China’s university-industry co-application networks; (2) Connecting China’s patent database to China’s university information database. Analysis of how the increase of university financial budgets and the number of faculties will impact the university-industry co-application; (3) Conducting data structuring and database development works. For example, connecting IIP Japan patent database to Japan university inventor database (Researchmap database), with the purpose of identifying university faculty inventors from IIP patent database, and extracting university-industry co-invention patents, which are applied by firms, although inventors include both firm inventors and university inventors; or connecting IIP Japan patent database to Patstat European patent database. As a result, all inventor information which are in the IIP Japan patent database in the Japanese language now have corresponding information that in English in the Patstat database. The IIP Japan patent database can now be connected to world scientific paper databases.
There were main four achievements in my internship at RIETI:
(1) The mentioned connection of the IIP Japan patent database to the Patstat European patent database. As a result, inventor and applicant information in IIP, which are in Japanese, are now connected to inventor and applicant information in Patstat, which are in English. This result can be utilized for several future research, for example, connecting Japanese inventor information in the IIP Japan patent database to world scientific paper database; disambiguation of Japanese inventor in IIP patent database and so on. (2) Identification of university faculty inventors from the IIP Japan patent database by connecting the IIP database to the Researchmap database; (3) Identification of Japan’s university-industry co-application and co-invention patents from the IIP patent database. (4) Connection of China’s patent database to China’s university budget database. Identification of China’s university-industry co-application patents form China’s patent database. The network indicators of Japan and China university-industry co-application patents have been calculated and analyzed by comparing the involvement patterns of Japan and China’s university-industry co-application networks.
