Promoting advantageous and characteristic agriculture is an important task of the rural revitalization strategy, and exploring efficient and appropriate development models is the key to the sustainable development of characteristic agriculture in ethnic minority areas.Based on the new endogenous development theory,this paper takes the formation process of characteristic agricultural development model in Xide County as a case sample, and uses multi-case study method to explore the characteristic agricultural development model and its internal mechanism in ethnic minority areas.The results show that the characteristic agricultural development mode of ethnic minority areas is influenced by the three factors of resource integration,diversified participation and development identity,and the interaction of the three factors has formed three characteristic agricultural development models in ethnic minority areas:collective mobilization,internal cooperation and internal-external pairing.
