In light of the rapid growth of South Korea and China’s R&D expenditure and the change of global R&D distribution since the two countries emerged into world R&D club, the present study attempts to investigate R&D spillover effects from the seven R&D countries including G5, South Korea and China. In addition to direct spillovers, we also take into account indirect spillovers from the seven R&D countries while examining the impact of international spillovers on the productivity growth and industrial competitiveness of the OECD countries. The sample countries are divided into two subgroups including major R&D countries and rest-of-OECD countries. Empirical results indicate a statistically positive effect of direct spillovers on major R&D countries’ productivity growth and industrial competitiveness. For the group of rest-of-OECD countries, indirect spillovers are found to be a driver for productivity growth but in the mean-time a crucial factor that can dampen industrial competitiveness. However, when taking into account the indirect effect that indirect spillovers work through productivity growth, the results suggest indirect spillovers can generate positive effect on industrial competitiveness for the rest-of-OECD countries. Therefore, it is important to incorporate the notion of indirect spillovers explicitly into modeling the impact of international spillovers. |
