the impact of internal r&d and technology imports on iranian manufacturing industries' output

generally, developing countries are not able to invest enough on r&d; therefore, they try to get benefit from knowledge spillover, as an external r&d.; this paper tries to investigate the impact of r&d; expenditures and imported intermediate goods, as a proxy for technology imports, on value added of iranian industries. to that end, we use a panel data set of iranian two-digit isic manufacturing industries, over the period 1995-2006. the results show that both internal r&d; and technology imports have a positive and significant effect; and that the technology imports has a larger effect. any attempt by the government to promote internal r&d; and interaction with the rest of the world is recommended. jel classifications: c23, f14, l60, o3.
