Knowledge diffusion from FDI and Intellectual Property Rights

Using a unique firm-level dataset of large, publicly traded firms in 22 (mostly) developed countries, we find partial support for these expectations. Strong IPR indeed reduces horizontal knowledge diffusion, while it stimulates backward (to suppliers) knowledge diffusion. Somewhat unexpectedly however, we also find that forward (to customers) knowledge diffusion decreases with IPR strength. In general, and in line with earlier literature, the results regarding backward knowledge diffusion are most robust to changes in model specification.

Our results contribute to the debate regarding the desirability of strengthening national IPR systems, and suggest that local firms might indeed benefit from this through their (backward) linkages with multinationals. Additionally, our results suggest that the moderating effect of IPR strength might partly explain the inconclusive results in the FDI knowledge diffusion literature.
