Abstract
The purpose of this study is to explore the causal system between entrepreneurial leadership and turnover intention of employees by examining the mediating effect of affective commitment and the moderating effect of person-job fit in start-ups. A quantitative approach was used to test the hypotheses and data were collected through the internet questionnaire tool. The authors selected employees from ventures newly established within the past five years and finally collected 427 questionnaires. The authors then used the hierarchical regression analysis method of Baron and Kenny for test mediating effect and the Hayes bootstrapping method for the test moderating effect by using Hayes' SPSS PROCESS macro. The results demonstrated that affective commitment functions as a mediator and person-job fit functions as a moderator. This paper provides implications for start-up leaders that entrepreneurial leadership is an effective style of leadership and plays a crucial role which accompanies the development of venture.
