Drawing upon transformational leadership and job characteristics theory, this study develops a research model to examine the impact mechanism of direct supervisor’s leadership behaviors on employees’ extended use of information systems. A field survey was conducted in China and empirical data was collected from 299 employees from both IT and non-IT industries. Structural equation modelling analysis results suggest that transformational leadership is positively associated with employees’ perception of job autonomy, which in turn promote IS extended use. Specifically, IT innovativeness is identified as a significant moderator that strengthens the relationship between transformational leadership and IS extended use. Theoretical and practical implications are discussed in the final section.
