Abstract This study introduces both the consistent and differentiated transformational leadership into the response relationship and adopts the SPSS18.0 and AMOS21.0 in its regression analysis and validity test. Through an empirical analysis of 253 employees, the paper reveals the waveform effect of differentiated transformational leadership on innovation performance. It is found that there is significant waveform effect on innovation performance in both consistent and differentiated transformational leadership. In other words, the boosting effect and restraining effect of consistent and differentiated transformational leadership will come into play in turns. The results extend the scope of explanatory variables and research content of differentiated transformational leadership. This study provides a new research path for future theoretical discussion of differential transformational leadership by combing its influence on innovation performance.
