Abstract
The number of industry-university (I/U) cooperative research has increased four times from 1,035 in 1991fy to 4,187 in 2001fy in Japan. However, there appears to be lack of empirical analysis for such a l/U network. This paper shows the analytical results of I/U cooperative research using actual data which have been conducted by two universities. The results reveal that the activities of I/U cooperative research have been received the influence by university characteristics such as university locations, and by corporate characteristics such as company sizes. And the result shows that the "concentration" and "diversification" have been occurred in I/U cooperative research. We indicate the possibility of dividing into three clustering groups in the geographic distance between Industry and university.
