Using the sample of non-financial listed companies in Shanghai and Shenzhen A shares, the impact of senior managers' R&D background and power on enterprise risk-taking was empirically tested. The results show that both the R&D background of senior executives and the R&D background of senior executives have a significant role in promoting enterprise risk-taking. The above conclusions are still valid after a series of robustness tests. The mechanism test finds that the increase of enterprise innovation investment plays a part of intermediary role in the process of executives' R&D background and power promoting enterprise risk-taking. Further distinguishing high-tech industries, finds that the promotion effect of senior managers' R&D background on enterprise risk-taking is only significant in high-tech industries, while the promotion effect of senior managers' R&D background power on enterprise risk-taking is significant in both high-tech and non high-tech industries.
