Does insiders share pledging stifle innovation? Evidence from China

We examine the relation between insiders share pledging activities for personal loans and firm innovation. Firstly, we find a negative effect of both the existence of pledging and the intensity of pledging activities on firm innovation, measured by R&D and patent application. Pledging by insiders with decision rights is associated with a 4.6% decline in R&D activities and 0.5% decline in patent applications, respectively, which accounts for 4.0% and 10.6% of the mean of each variable. This result holds using a propensity-score matched sample. In addition, we instrument pledging activities by financing constraints faced by other firms controlled by the same controlling insiders who pledge shares. IV estimation yield similar results. Secondly, we find share pledge activities have more pronounced effect on firm innovations when firms are located in areas with strong property rights protection, when firms are non-SOEs, or when pledging insiders serve on corporate boards. Lastly, we also find a negative effect of share pledging of other firms with common shareholders on firm innovations of interest. Overall, our findings suggest that pledging shares by insiders stifle firm innovation because share pledging reduce insiders' preference for risk taking.
