ABSTRACT
This paper focused on role-based public leadership's impact and internal mechanism on subordinate taking charge behavior (TCB). The explanatory model of rationality and value dual paths was proposed and verified through hierarchical regression and bootstrap tests, with the data from a questionnaire survey to the Bureau of Commerce. The main conclusions are as follows: (1) Public service motivation is a mediating variable between public leadership and TCB;(2) political skills have a double-edged sword effect. Political skills positively moderate the impact of public leadership on TCB. Meanwhile, it negatively moderates the effects of public leadership on public service motivation and the effects of public service motivation on TCB;(3) under the high political skill level of subordinates, public leadership has a direct impact on the TCB, while under the low political skill level of subordinates, the direct effect of public leadership on the TCB is insignificant.
