Sustainability, Vol. 11, Pages 2311: Interest Rate Marketization, Financing Constraints and R&D Investments: Evidence from China (Sustainability)

Under the background of the initial completion of Chinese interest rate marketization process, this paper aims to test the actual impact of interest rate marketization on micro-enterprise research and development (R&D) investments financing. Based on the current situation, we put forward the assumption that Chinese enterprises are generally facing financing constraints in R&D investment. The interest rate marketization, which reduced government intervention in fund pricing, helps alleviate financing constraints, especially for non-state-owned enterprises. This paper focuses on the moderating effect of interest rate marketization on financing constraints and R&D investments. The interest rate marketization index is constructed from three indicators: interest rate determination ways, interest rate fluctuation restrictions, and real interest rate level. We use the Euler-equation investment model to test the financing constraints of R&D investment. Based on panel data of listed firms for 2007–2016, we find that R&D investment faces wide financing constraints, and interest rate marketization alleviates financing constraints. More specifically, financing constraints are more significant for non-state-owned firms than for state-owned enterprises, and the deepening marketization of interest rates can effectively alleviate the financing constraints of non-state-owned enterprises.
