概要 R&D in foreign affiliates and technology transferred from their parent firms are important potential drivers of productivity in host countries. In this paper we examine the simultaneous impact of local R&D and intra-firm international technology transfer on productivity growth in foreign affiliates. We estimate a dynamic productivity model on a large sample of Japanese manufacturing affiliates worldwide in 1996-1997 and 1999-2000. We find that both affiliate R&D and intra-firm technology transfer contribute to productivity growth, while technology transfer exhibits decreasing marginal returns. The two sources of technology are complements: use of one source of technology increases the marginal impact of the other.
