Characteristics of Knowledge Interactions between Universities and Small Firms in Japan
基于大学层面数据，分析了日本产学合作的特征，发现高研究潜力的科学家通过联合研究等渠道与大企业直接联系，而低研究潜力的科学家则通过联络办公室的中介，以技术咨询等方式与小企业合作。
Based on university-level data, characteristics of industry-university linkages in Japan were examined. The results of statistical analysis present a contrasting picture regarding the characteristics of knowledge interactions according to the size of industrial partners. On the one hand, on the basis of direct connections, university-based scientists with high research potential are linked with large firms in broad areas through highly interactive spillover channels such as joint research. On the other hand, through the intermediation of liaison offices, university-based scientists with low research potential are linked with small firms, through less interactive spillover channels such as technical consultation.
