Abstract: Contract agriculture is an important organizational form of modern agriculture, but the development of contract agriculture has been plagued by the problem of performance. Based on the survey data of 470 tea farmers in Anhui Province, this paper uses binary logistic regression model to analyze the impact of the degree of part-time employment on the performance behavior of order farmers; The intermediary effect model is used to further explore the transmission mechanism of the impact of the degree of part-time industrialization on the contract performance behavior of tea farmers. The results show that the degree of farmers’ part-time operation has a significant positive impact on farmers’ performance behavior; From the transmission mechanism analysis of the impact of the degree of part-time industrialization on farmers’ performance behavior, it is found that the degree of part-time industrialization can reduce farmers’ business scale, and then improve farmers’ performance behavior.
