Effect of buyer dependency of subcontracting SMEs on R&D investment

Abstract

PurposeThis study aims to focus on the subcontracting relationship between small and medium-sized enterprises (SMEs) and business group buyers and analyze the effect of the level of buyer dependency on R&D intensity. The primary prediction is that buyer dependency and R&D intensity have a non-linear relationship, showing an inverted U-shaped relationship. Furthermore, the moderating effect of founder CEOs and internationalization is explored.Design/methodology/approachA sample of 546 firm-level survey responses were collected from Korean subcontracting SMEs provided by the Ministry of SMEs and Startups and the Korea Venture Business Association.FindingsA lower level of dependency on business group buyers promotes R&D investment, while excessive dependence reduces R&D investment. Moreover, founder CEOs and internationalization decrease the effect of buyer dependency on R&D investment, implying that both firm characteristics are associated with a long-term focus and promote R&D investment.Research limitations/implicationsThis research contributes to the literature on the special form of the buyer–supplier relationship, that is, subcontracting. Subcontracting has a contradictory effect on R&D investment based on large group buyer dependency, and this relationship is moderated by the founder CEO and internationalization.Practical implicationsThis study provides insights to managers and practitioners governing SME subcontracting by showing that the level of buyer dependency is better managed in promoting innovation, and the long-term perspective allows SMEs to be less affected by buyer dependency.Originality/valueThis study extends the literature by focusing on the non-linear relationship between buyer dependency and R&D intensity of subcontracting SMEs. This approach addresses the contradicting results suggested by prior supply chain management literature and suggests that the level of buyer dependency should be considered when analyzing the subcontracting relationship.
