Abstract:Disruptive technologies have the transformative effect of reshaping the landscape of The Times, and the style of project leadership is often closely related to project performance. Based on the individual-environment matching theory and leader-member exchange theory, this paper uses a mixed empirical and qualitative approach to explore how leadership style influences project performance through leader-member exchange, leader-member matching, and knowledge sharing. Based on a questionnaire survey of 339 members of disruptive technology projects, we find that ethical leadership can directly affect leader-member matching and leader-member exchange, while service-oriented leadership can only indirectly affect leader-member exchange through leader-member matching. Leader-member exchange can positively influence cooperation satisfaction directly or indirectly through knowledge sharing, and cooperation satisfaction positively affects project performance.
