Abstract
This paper provides an empirical assessment of the effect of national and international knowledge spillovers on innovation at a finely defined sectoral level for six major industrialised countries over the period 1981-1995. International spillovers are always found to be effective in increasing innovative productivity. The paper then uses self-citations to investigate the role of prior R&D experience in enhancing a country¿s ability to understand and improve upon external knowledge (absorptive capacity). The empirical results show that absorptive capacity increases the elasticity of a country¿s innovation to both national and international spillovers. The larger the gap of a country with the technological leaders, the weaker is this effect, but the larger is the country¿s potential to increase it.
