The Impact of R&D on the Singapore Economy: An Empirical Evaluation

Abstract

Much of the literature on the impact of R&D on economic performance is founded on the advanced countries, where the intensity of R&D expenditure has been relatively high and stable for many years. In this paper, we provide empirical estimates of the impact of R&D on the economic growth of a Newly Industrialised Economy, Singapore, where R&D expenditure intensity has been low initially, bur rising rapidly in recent years. The Cobb-Douglas based analysis provided empirical evidence that R&D investment in Singapore had a significant impact on its total factor productivity performance in the last 20 years and established a long-term equilibrium relationship between R&D investments and TFP. However, compared to the OECD nations, the impact of R&D investment on economic growth in Singapore is not as strong, as evidenced by lower estimated elasticity values. The long run elasticity of output with respect to R&D was computed to be 8.1% for Singapore compared to long run elasticities of over 10% estimated by other researchers for OECD countries. This suggests that Singapore still has some way to go in catching up with the advanced nations in terms of R&D productivity. This not only means increasing the level of R&D intensity in Singapore but also more efficient exploitation of domestic R&D activity.
