In this paper we present latest facts about the R&D activities of German multinational companies abroad and R&D activities of foreign companies in Germany. These results confirm that Germany is still an attractive location for R&D activites of multinational companies in many technological...

This paper contributes to the debate on the internationalization of the R&D activity of multinational enterprises (MNEs). Specifically, we examine the following research questions: (1) What are the determinants of the MNEs’ R&D internationalization level? (2) What types of internationalization...
