The effectiveness of public R&D subsidy on SMEs’ innovation capability and catch-up in the Korean manufacturing industry

Abstract

This study investigates the effect of R&D subsidy associated with R&D projects on the productivity and internal capacities of Korean manufacturing small- and medium-sized enterprises (SMEs). It also addresses the difference in effectiveness attributed to the characteristics of such projects. We constructed distinctive firm-level panel data combining the National Science and Technology Knowledge Information Service and Korea Enterprise Data databases and used stochastic frontier analysis with multivariate matching techniques. The results reveal that subsidised R&D projects did not help Korean SMEs in improving productivity and efficiency. Compared with the control group, which had similar external features, beneficiaries showed worse productivity growth as well as efficiency changes. Moreover, the effects of R&D subsidies differ depending on project characteristics. Specifically, the amount and period of R&D subsidy had a positive effect on catch-up but a negative effect on SMEs’ innovation capacity. These results demonstrate the need for renovating the current support system for SMEs’ R&D activities in Korea.
