Abstract

To facilitate R&D investment, it is necessary to prove a validity of economic effects of the R&D investment. This paper examines the direct effect of R&D of electrical and electronic industries (EEI) on economic growth as well as the indirect effect via the development of technical and scientific skills and new technologies. The model we estimated for the period 1977-93 on a time-series set, and model testing was conducted through the use of LISREL analysis. The effect of R&D of EEI was observed particularly through technical and scientific skills as measured ba the number of scientists and engineers. However, ther did not seem to be any statistically visible evidence of direct effect from R&D of EEI to the economy.
