Abstract: The theoretical divergence of dynamic capabilities lies the differences affecting on competitive advantage directly or indirectly. Organizational routine is the core of dynamic capabilities, exploring the relationship with competitive advantage is very important for resolving the theoretical divergences. Because of the complexity and abstraction of organizational routines, the research of exploring the derivative paths of competitive advantage from organizational routines perspective is rare. In this paper, on the basis of revealing the nature and derivative mechanism of organizational routines, we explored the relationship between organizational routines renewing and competitive advantage under different levels of environmental uncertainty. The empirical results show that: organizational routines renewing is the result of organizational learning. In the low dynamic environment, organizational routines renewing have a positive impact on competitive advantage. But in the high dynamic environment, revising organizational routines does not significantly affect the competitive advantage; creating organizational routines will have a negative impact on the competitive advantage. At this time, dynamic capability is not the direct source of the competitive advantage.
