摘要：Using the OLI paradigm as theoretical framework, we explain econometrically why a firm
invests in foreign R&D (model A), and, if it does, which factors determine the level of foreign
R&D expenditures (model B). It turns out that the pattern of explanation is quite similar for both
types of decisions. In both cases, O- and I-advantages are the main drivers of foreign R&D,
whereas L-disadvantages of the Swiss location do not play any role. A descriptive analysis of a
series of motives of Swiss firms for performing R&D abroad shows that market-seeking is the
most important motive. Knowledge-seeking and (human) resource-seeking are of intermediate
importance as motives of foreign R&D, whereas efficiency-seeking objectives are hardly
relevant. These results are fully in line with those of the econometric modelling. The findings of
both approaches imply that foreign and domestic R&D are complements rather than substitutes.
“Asset exploiting” is more prevalent as a strategy of foreign R&D than “asset augmenting”.
