Although the influence of leadership style on employee attitude, organizational culture and job performance in different contexts has been discussed in a large number of studies, the extent to which leadership styleis affected by situational characteristics has not been well understood. With the goal to recognize how situational factors motivate different leadership styles. Based on social exchange theory, similar‐attraction theory and trust theory, this paper analyzes the relationship between different types of leadership styles and situational characteristics through literature review. This paper puts forward three situational factors that influence leadership style: personal characteristics of leaders, environmental factors and employee characteristics. And also discusses the mediating role of employees in the influence of leadership style on organizational performance, acting as both the outcome variable and antecedent variable of leadership style, and summarizes the existing research results. Finally, the implications and limitations of the study are discussed, and the findings may have implications for organizations seeking to improve leadership effectiveness.
