Relationships among international joint research, knowledge diffusion, and science convergence: the case of secondary batteries and fuel cells

ABSTRACT Recently, innovation through convergence is being conducted actively. Therefore, understanding the process of facilitating convergence is very important for innovation. According to some studies, diffusion is a factor promoting convergence, and is affected by international joint research (IJR) networks. The objective of this study is to investigate the relationships among IJR networks, knowledge diffusion, and science convergence. For this purpose, we used network analysis and regression analysis, based on scientometric analysis in the fields of lithium ion batteries and fuel cells. The results are as follows. First, institutes with high centrality in IJR networks are more likely to be early adopters, and IJR networks in which knowledge is diffused are scale-free. Second, knowledge diffusion is an important factor in promoting science convergence. This study is significant as it determines that knowledge diffusion may significantly help increase science convergence and IJR networks, one of the major sources of innovative technologies.
