The Impact of Financing Constraints and Agency Costs on Corporate R&D Investment: Evidence from China*

This study investigates the association between financing constraints/agency problem (agency costs) and corporate R&D investment in China by using the two-tier stochastic frontier model initially developed by Kumbhakar and Parmeter (2009) in light of the Euler equation analysis framework. The results show that there is a significantly negative association between financing constraints and firms' R&D investments and a significantly positive relationship between agency costs and R&D investments. Thus, financing constraints lead to R&D underinvestment, while agency costs cause R&D overinvestment by the sample firms. However, government subsidies have a positive moderating effect on the relationships. The impact of financing constraints and agency costs on R&D investment varies slightly by firms in different geographical regions, industries, business ownerships, and years.
