Corporate governance and R&D investment: the role of debt financing
研究美国上市制药企业2009-2018年数据，发现公司治理机制促进研发投资，债务融资抑制研发投资，且债务融资在两者关系中起调节和部分中介作用。
Abstract This paper examines the role of debt financing in the relationship between corporate governance and research and development (R&D) investment using a sample of publicly traded U.S. pharmaceutical firms from 2009 to 2018. The results show a positive and significant association between corporate governance mechanisms (such as board size, board independence, board gender diversity, and ownership concentration) and R&D investment and a negative and significant association between debt financing and R&D investment. In addition, we show that debt financing plays a moderating role and a partial mediating role in the relationship between corporate governance mechanisms and R&D investment. Specifically, debt financing attenuates the negative effect of board size on R&D investment and accentuates the positive effect of ownership concentration on R&D investment. Our study helps to shed light on a close and complex relationship existing between the firm’s choices of corporate governance, debt financing, and R&D investments, which the previous literature has so far examined in a partial and fragmented way. To ensure effective R&D investment, firms need to consider the effect of debt financing on corporate governance decisions.
