Equity pledge of controlling shareholders, property right structure and enterprise innovation efficiency: evidence from Chinese firms

Abstract

The innovation efficiency of an enterprise is subject to the behavior of the innovation subject, while the equity pledge behavior of the controlling shareholder not only brings convenience for innovation investment and financing, but also brings risks which has an impact on the innovation output of the enterprise. In this paper, we investigate how equity pledge of controlling shareholders affect the enterprise innovation efficiency using the data of China’s A-share listed companies from 2014 to 2020, and examine the effect of property right structure on the relationship between them from the two dimensions of equity nature and equity concentration. We find that equity pledge of controlling shareholders are signifcantly negatively related to innovation efficiency, meaning that equity pledge inhibits the innovation behavior of enterprises and reduces the innovation efficiency. We further provide evidence to show that the impediment effect of equity pledge of controlling shareholder on enterprise innovation efficiency is more pronounced in non-state-owned enterprises and decentralized equity enterprises. Moreover, our analysis shows that different equity concentration levels have different effects in the process of equity pledge affecting enterprise innovation efficiency and the effect of concentrated equity enterprises is lower than that of decentralized enterprises.
