Abstract:Artificial intelligence (AI) is an important driving force to strengthen firm R&D investment and thus drive innovation, while managerial power is closely related to firm R&D investment decisions in the business management. However, existing research on how chief executive officer (CEO) power affects the role of AI is not yet clear, which is not conducive to revealing the mechanism of AI’s role in firm R&D investment in depth. This paper divides CEO power into four dimensions: organizational power, owner power, prestige power and expert power, and constructs an empirical research model with them as moderating variables to explore the impact of AI on R&D investment and the moderating role of CEO power in the process. In addition, the heterogeneity test is conducted based on the firm industry and location, and double difference method (DID) is used to analyze the causal analysis relationship of the role of policy documents on firm innovation. The A-share manufacturing listed firms in Shanghai and Shenzhen are selected as the research samples. The results show that there is a significant positive relationship between AI and R&D investment; CEO organizational power and CEO owner power have a positive moderating effect on the relationship between AI and R&D investment; CEO prestige power and CEO expert power do not have a moderating effect on the relationship between AI and R&D investment. Based on the empirical results, it is proposed that firms should reduce the interference of the board of directors in the CEO’s decision-making regarding organizational adjustments, and at the same time encourage employees to actively cooperate with the CEO’s reasonable decisions.
