Environmental policy and R&D productivity: A case study from the Korean Emissions Trading Scheme

This study investigates the relationship between emissions trading schemes and Research and Development (R&D) productivity based on data from manufacturing industries participating in the Korean Emissions Trading Scheme (KETS). First, this study estimates the total factor R&D productivity by industry, and it is confirmed that changes in R&D productivity vary across industries. The total factor R&D productivity in Korea has been decreasing, but the annual growth trend has been increasing rapidly due to the introduction of the KETS. Based on the estimated R&D productivity, panel data model estimation is executed to reveal the effect of environmental policy on R&D productivity. Empirical results confirm that environmental policy plays a vital role in promoting R&D productivity, and policy stringency affects R&D performance. The results also find that the environmental policy encourages enterprises to participate in KETS for improving R&D productivity.
