“…The mean cost of debt (variable R d ) is 0.025, with a minimum value of 0.001 and a maximum value of 0.080, implying that the cost of debt varies greatly in our research sample. The mean cost of debt is similar to that reported in previous studies, for example, 0.033 in Zou and Adams's (2008) research, and the means of the control variables are also similar to those reported in previous research by Chen, Ma, and Wu (2019), Jiang, Lee, and Yue (2010), Lin, Ma, Malatesta, and Xuan (2011), and Zou and Adams (2008), suggesting that our sample is comparable with samples used in other studies. Table 5 presents the Pearson correlation matrix of the firms' major characteristics with the average variance inflation factor (VIF) being 2.37, indicating that multicollinearity is not a concern.…”
