Abstract:The competition among enterprises changes from relative static mode to dynamic mode due to economic globalization and environmental uncertainty. Hence it is essential for enterprises to obtain sustainable competitive edge by acquring,integrating and reconstructing resources through dynamic capabilities. Based on the survey data of 123 small and medium-sized agricultural e-commerce enterprises in Ganzhou,Jiangxi Province and Lishui,Zhejiang Province,this paper empirically analyzes the relationship among enterprise innovation behavior,dynamic capability and enterprise performance by using mediating effect model. The research shows that the three dimensions of the dynamic capability have a significant positive effect on the performance of the enterprise,and the innovation behavior of the enterprise has an intermediate role between the dynamic capability and the enterprise performance relationship. Specifically,the enterprise knowledge acquisition ability improves the enterprise performance through the internal system reform and the market development behavior; the enterprise integration utilization ability improves the enterprise performance by acting on the enterprise new technology adoption behavior; the enterprise reconstruction transformation ability improves the enterprise performance by acting on the enterprise market development behavior. Therefore,it is proposed that the small and medium-sized agricultural product e-commerce enterprise,based on its own capability advantage,should adopt the corresponding innovation behavior,which will help to improve the performance.
