DIMINISHING RETURNS TO R&D INVESTMENT ON INNOVATION IN MANUFACTURING SMEs: DO THE TECHNOLOGICAL INTENSITY OF INDUSTRY MATTER?

Abstract: This paper examined the nonlinear R&D-innovation relationships of SMEs (small and medium-sized enterprises) and the differences in the strength and productivity of R&D investment between low-, medium-, and high-tech industry sectors. Using 2740 firm data in South Korea, this study found that R&D investment has an inverted U-shaped relationship with registered patents such that patents increase at a decreasing rate as R&D investment increases. The relationship between R&D investment and inno… Show more

“…In view of the foregoing, we therefore lend support to the strand of literature that emphasizes that in cross-border deals, industry does matter (Datta et al , 2005; Kim, 2018; Rajagopalan and Datta, 1996; Singal, 2014; Su, 2015; Perrons and Platts, 2005; Yang et al , 2007). Prior research has shown that industry is an important variable affecting CEO characteristics (Rajagopalan and Datta, 1996), organizational learning (Weerawardena et al , 2006) and patent registration (Kim, 2018). There is further literature on capital markets (Merkley et al , 2017), stakeholder management (Griffin and Koerber, 2006), labor productivity (Datta et al , 2005) and earnings management (He and Yang, 2014).…”

“…As a result, product quality in a market with spillovers depends not only on producer's individual product R&D efforts, but also on the product R&D efforts put by producer's rivals. Function The assumption that the marginal returns on R&D are decreasing has its empirical base, e.g., in Scherer (1980), Griliches (1998) or Kim (2018). According to Kamien and colleagues (1992)…”

“…Again, there is much evidence of improvement and then diminishing returns from R&D intensity (Kim, 2018), and this holds true for SMEs whose activities span national boundaries (Booltink & Saka-Helmhout, 2018). Hence, this would suggest that taking account of R&D spend would not significantly change the inverted U-shaped relationship between diversification and credit scores.…”
