However, the investment in innovation decision-making of enterprises will be affected by many factors, and more and more scholars are beginning to pay attention to the element of overconfidence of enterprise managers. Managers' overconfidence is a common mental state. When managers are overconfident, they will make decisions more easily. So, does the manager's overconfidence affect the company's innovation investment? Existing research results show that overconfident managers can promote enterprise innovation investment, but overconfident managers are a double-edged sword.
