For this purpose, an endogenous growth model is used in which production is a function of labor, capital stock, human capital, internal R&D expenditure, technology imports, multiplication of employment share of human capital and technology imports, and multiplication of internal R&D expenditure and technology imports. We estimate this model for 21 industrial groups by applying panel data approach. The results indicate that internal R&D expenditure and technology imports have a significant positive effect on value added of Iranian large industries. Also, research findings emphasize the positive effect of human capital in absorbing imported technology and consequently, increasing industry value added. https://pajooheshnameh.itsr.ir/article_10787_93d2641dc9b9bfc506986533d396cbfa.pdf
