Notes: This table presents the 2SLS/IV results of MARank, IPRI, the interaction between MARank and IPRI and control variables on LogRD from 2011 to 2020. Year dummies are not reported for brevity. P-values are reported in parentheses. The statistical significance is denoted as *p < 0.05; **p < 0.01 and ***p < 0.001, respectively. Refer Table 2 for variable definitions
