Abstract
This study aims to quantitatively evaluate the relationship between activities for industry-academia collaboration and influencing factors in universities. The data on activities for industry-academia collaboration, and the data on basic research and university indexes, were collected and analyzed. As a result, it was revealed that the number of joint research per professor was influenced by the number of research papers per professor, the settlement amount of universities per professor, the fields of faculties, the scale of staff for industry-academia collaboration and the number of graduate students per professor, the expense of joint research per professor was influenced by the number of research papers per professor, the number of graduate students per professor, the scale of staff for industry-academia collaboration and the fields of faculties, the number of contract research per professor was influenced by the number of research papers with frequent citations per professor, the fields of faculties, the scale of staff for industry-academia collaboration and the number of graduate students per professor, the expense of contract research per professor was influenced by the number of research papers with frequent citations per professor and the scale of staff for industry-academia collaboration, and the expense of scholarship donations per professor was influenced by the existence of medical departments, the founders, the number of research papers per professor and the settlement amount of universities per professor, in order of strength. The explanatory variables indicating basic research had the strongest influence on the explained variables except the expense of scholarship donations per professor, and the existence of medical departments had the strongest influence and the explanatory variables indicating basic research had the third strongest influence on the expense of scholarship donations per professor. It was also revealed that some explanatory variables indicating university indexes influenced the explanatory variables indicating basic research. To promote activities for industry-academia collaboration, it is imperative to strengthen basic research, and it is also expected to improve university indexes influencing them.
