Today’s international division of labor between and within companies, transfer and creation of knowledge beyond “time & space” have much more possible than ever before, mainly because of the evolution of ICT based on digital and software technology. At the same time, this not only becomes a factor for geographically decentralizing research and development (R&D) capabilities, but also for concentrating R&D capabilities for companies and countries that can strategically utilize them. Correspondingly, IBM, for example, has augmented the number of nationalities of inventors in its US patents, including co-inventor ones, from 12 nationalities in 1990, 24 in 2000, 37 in 2010, and to 54 in 2015, apart from US nationality.
In other words, US IT multinationals have strategically responded to the international and geographical decentralization of capable R&D human resources. Such internationalization of R&D has promoted not only the utilization of overseas R&D bases, but also the international networking of R&D activities that create technical knowledge through international collaboration.
However, conventional researches on international networking of R&D activities have centered on qualitative empirical research based on individual case studies, which have not quantitatively clarified the networking of R&D activities.
Therefore, after overviewing the internationalization of R&D activities of seven US IT companies, which are positioned in top ten in the number of US patent ranking, including Facebook, which has a rapidly increasing number of patents, the paper specifically examines Google, IBM, and Japanese Canon in order to visualize and quantitatively clarify networking structures of international joint R&D. Through network analysis based on graph theory, the characteristics of the network structures of R&D activities by the above three companies are quantitatively grasped by indicators such as density, transitivity, eigenvector, etc.
Finally, this paper points out that the international networking of R&D activities in terms of the nationalities of inventors of the patented technologies of the two US companies, among others, are quantitatively reflected.
