This paper addresses the question of which variables have what kind of
impact on the decision to locate new R&D facilities in countries diff
erent from the home country of a corporation. In the first section of
the paper we demonstrate the complexity of this question by referring
to empirical research, managerial statements and literature. We then d
evelop a conceptual model for the location decision of international R
&D activities. This is based on Porter's (1990) framework of the facto
rs constituting the competitive advantage of nations. In the final sec
tion of this paper we show how such a model helps us to understand and
also to explain a number of management issues related to global R&D a
ctivities.
