The paper takes the production data of 70 vineyard farmers in Changsha, Yueyang, Loudi, Huaihua and Changde in Hunan as the research sample, and studies the relationship between farmers' professional cooperatives and farmers' productive benefits. The results show that there is a difference in production efficiency between the farmers' professional cooperative members and non social farmers, and the non members are in the grape sales. The four production benefit indexes of sale price, per mu capital cost, per mu income and net income per mu are lower than members, which shows the superiority of joining professional cooperatives. In order to encourage more farmers to enter the society, it is suggested to increase the demonstration point of farmers' professional cooperatives, and to increase the support for the special agricultural products of the farmers' professional cooperatives so as to increase agricultural production and increase farmers' income and promote the process of agricultural modernization in China.
