Abstract
This paper analyses the effects of R&D investment on patent in Korean manufacturing firms during the period 1984-99. The data contains 140 companies which listed in Korea Stock Exchange(KSE). We observed that the relative shares of R&D investments and patent applications are much higher in scientific firms than in the other firms. The regression results show that R&D investment has significantly positive effects on the growth of patent application and registration. And the effects of R&D on patent turns out to be stronger in scientific firms than the other firms. The firm size and the capital intensity also have an important effect on the propensity to patent.
