Abstract
In the context of a dynamic environment and increasing competition, innovation is the key for companies to gain long-term growth. And narcissism, as an important psychological factor influencing CEOs to make corporate decisions, has a significant impact on corporate innovation strategies. This study explores localized dimensions and ways of measuring narcissism among Chinese CEOs. Based on the upper echelons theory, using data from R&D-intensive firms listed in Shanghai and Shenzhen A-shares from 2015-2020, this study empirically examines the effect of CEO narcissism on exploratory and exploitative innovation and the mediating role of corporate social responsibility. The results show that: CEO narcissism has a positive effect on corporate ambidextrous technological innovation and a more significant effect on exploratory innovation; the mediating role of corporate social responsibility is all verified. These findings provide a reference for listed companies to select and hire CEOs scientifically and rationally, and have important implications for companies to develop long-term innovation strategies.
