Interdependence between Overseas and Domestic R&D Activities: Evidence from Taiwanese Multinationals

The purpose of the present paper is to examine the interdependence between the overseas and domestic R&D activities of Taiwanese multinational enterprises (MNEs). Because domestic (overseas) R&D activities may enter the overseas (domestic) R&D determination equation as an endogenous right-hand side variable, the traditional estimation approach will be invalid due to the endogeneity problem. Therefore, it is proposed that the two R&D decisions be estimated using a simultaneous Tobit model. The results in this paper indicate that Taiwanese MNEs that engage in higher levels of domestic R&D activities will engage in overseas R&D activities. Interestingly, it is also found that Taiwanese MNEs increase their overseas R&D activities in developed countries instead of their domestic R&D activities, whereas Taiwanese MNEs that engage in overseas R&D activities in less-developed countries will raise their domestic R&D activities. As for the other common determinants of the overseas and domestic R&D activities, firm size and the capital-labor ratio are found to be the main factors.
