Tracing the footprint of knowledge spillover: Evidence from U.S.-China Collaboration in Nanotechnology

The impacts of international collaboration on research performance have been extensively explored in the last two decades. Most research, however, focuses on quantity and citation-based indicators. Utilizing the turnover of keywords, this study develops an integrative approach tracking and visualizing the shift of the research stream and tests it within the context of U.S.-China collaboration in nanotechnology. The results find evidence in support of the linkage between the emergence of new research stream of Chinese researchers with the event of U.S.-China collaboration. It also finds that the triggered research stream diffused further via extended coauthorship. Policy implications for both the U.S. and China science and technology development and resource allocation are discussed in the end.
