Outsourcing service is considered an effective path to achieve capital substitution for labor,which plays an important role in rural revitalization and agricultural modernization. Based on the household survey data of 302 rice farmers in Hunan and Anhui provinces,this paper used Probit model and IV-probit instrumental variable to analyze the impact of farmers’ part-time employment on the decision of outsourcing service. The results show that:(1) Both farmer’s labor part-time degree and income part-income degree are expected to impose a significant positive effect on the decision of outsourcing service. Compared with the technologyintensive service,farmer’s labor part-time degree plays a greater role in promoting the outsourcing of labor-intensive links. (2) Different types of rural households show different characteristics in the outsourcing behavior of technology-intensive links. Large-sized households tend to increase the expenditure on technology-intensive outsourcing services,while low-part-time households tend to reduce the expenditure in this link. After using instrumental variable to correct the endogenous issue between farmers’ part-time employment and agricultural production link outsourcing through instrumental variables,the results remain robust. Therefore,this paper proposes to further improve the productive service system,support the disadvantaged links,differentiate regulations for various outsourcing services and give full play to the scale economic effects of outsourcing service during production.
