Based on the Chinese Household Finance Survey (CHFS),this paper constructs objective measurement indicators respectively for the performance of agricultural entrepreneurship and nonagricultural entrepreneurship from the perspective of the heterogeneity of the entrepreneurial industry,uses the endogenous switching regression model to test the impact of credit constraints on the entrepreneurial performance of rural households,and further adopts the treatment effect model to estimate the loss of rural household entrepreneurial performance caused by credit constraints. The results found that credit constraints significantly restrict the entrepreneurial performance of rural households. For agricultural entrepreneurial households,expanding the scale of farmland operations has not significantly improved their permu agricultural output and unit agricultural production costs due to the credit constraints. Compared with households not subject to credit constraints,the permu agricultural output of households subject to credit constraints decreased by 119.4242 kg,and the unit production cost of agricultural products increased by 0.2097 yuan. For nonagricultural entrepreneurial households,increasing the amount of loans of households subject to credit constraints can significantly increase their net profit of production and operation compared with households not subject to credit constraints. If the credit needs of households subject to credit constraints are fully satisfied,the net profit may increase by 19,533 yuan. In addition,when the credit needs of entrepreneurial households constrained by demandoriented credit are fully satisfied,the improvement effect of their entrepreneurial performance is better than that of entrepreneurial households constrained by supplyoriented credit. The research confirms the negative impact of credit constraints on the entrepreneurial performance of rural households and estimates the losses. The results imply that,the rural financial market should be further reformed to effectively settle the matter of farmers’ entrepreneurial financing constraints,enhance farmers’ entrepreneurial performance,and improve the quality of farmers’ entrepreneurship in the process of optimizing the support policy system for farmers’ entrepreneurship and realizing rural revitalization.
