Based on theoretical analysis with the “SSCP paradigm”, this paper uses the survey data of farmers’ cooperatives in Jiangxi Province. We adopt survival analysis approach and the COX model to study the stability of farmer cooperatives “agriculture-supermarket docking” and determinants. The results show that these cooperatives “agriculture super docking” have greater stability including fisheries cooperatives, exemplary cooperatives and the government-established cooperatives. The effect of government policy and the cooperative ability are the most important factor affecting cooperatives “agriculture-super docking” docking relationship stability. Therefore, the government should guide cooperatives to participate in the “agriculture-supermarket docking”; at all levels of government guarantee of implementing the relevant policies; strengthen cooperatives to enhance their capabilities, and balance the business relationship between the supermarket and cooperatives.
