Abstract:Abstract: Based on the theory of dynamic competence, organizational learning and knowledge structure, this paper constructs the system dynamics model of farmers’ cooperative from knowledge search to knowledge creation, by simulating the relationship between Internet applied skills, knowledge search and innovation ability of farmers’cooperative, the way and evolution process of innovation ability of farmers’ cooperative are explored. To be specific, the influence path of farmers’ cooperative innovation ability: Internet skill training -- Internet application skill -- innovation ability; Evolution process: The absorptive capacity in the early stage is the main part gradually evolved to absorb, integrate ability common development, and finally forms the balanced development state of absorption, integration and original ability. On the one hand, this research breaks through the theoretical limitation of existing research on exploring the action mechanism of innovation behavior based on the perspective of enterprise; On the other hand, it makes up for the lack of literature that systematically analyzes the evolution mechanism of farmers' cooperative innovation ability from the dynamic perspective. The research conclusion can provide important scientific basis for the policy making of sustainable development of farmers’ cooperative
