Abstract: Existing studies show that cooperatives, as important new agricultural management subjects, play an important role in promoting farmers to increase their income and realize common wealth. However, some cooperatives have deviated from their original purposes and principles in the process of development, and some phenomena inconsistent with the nature of cooperatives have appeared. Alienation may hinder the development of the rural economy, lead to the waste and irrational allocation of rural resources, further aggravate the gap in the distribution of farmers' income, and restrict the development of the rural economy. This paper focuses on the impact of the “Matthew effect” of cooperative alienation on the common wealth. This paper intends to explore the impact of cooperatives on the common prosperity of farmers, and tries to answer three questions: first, whether the alienation of cooperatives hinders the realization of the common prosperity of farmers, and what is the mechanism. Second, what is the extent to which cooperative alienation hinders farmers from realizing common wealth.
