Abstract
Research and development (R&D) has been condsidered as the most important method for a rapid advancement of technology and manufacturing competitiveness and innovation. This study aims to assess R&D spillovers on the total productivity factors (TFP) of Iranian manufacturing industries in the period 2000-2008. This study employing two-stage GMM method uses statistical data of domestic R&D accumulation of industries in nineteen code of the two-digit ISIC, foreign R&D and imports of fifteen trading partners of Iran to measure the effect of R&D spillovers on the TFP of Iranian manufacturing industries. Results indicate that the interaction between human capital and foreign R&D accumulation, the interaction between import and foreign R&D accumulation, effects of external R&D accumulation and internal R&D have most positive impact on total factor productivity of Iranian manufacturing industries respectively. Internal expenditures on R&D in the chosen period have failed to provide new products and services and imperove competitiveness, technology and increasing TFP growth.
