Abstract
This paper shows the steady internationalization of R&D activities and the expansion of cross-border linkages in R&D in 22 US, European, Japanese and Korean electric-electronic multinational companies (MNCs). In contrast to previous studies that have emphasized input factors to measure the internationalization of R&D, this study focuses on output measures, namely, the roles played by overseas R&D facilities of MNCs in US patenting activities and the publication of scientific papers. Using these measures, this study demonstrates that globalization and networking of R&D activities by these MNCs have progressed both in terms of basic and industrial applications.
