Influencing factors analysis on credit constraints of pig breeding farmers

From the perspective of pig breeding farmers，this article summarized that the factors affecting household credit constraints had mainly three categories：basic characteristics，breeding behavior，credit situation. Using two-stage method from Heckman，by Probit model this paper analyed the factors of farmers’ credit constraints，and estimated the number of households credit demand，last got the credit needs of farmers，which was the gap. Empirical analysis showed that，in the variables of farmer basic characteristics，the head of household age and amount of labor had significantly positive impacts on farmers’ credit constraints；in the variables of breeding behavioral，the investment of fixed asset and term of pig farming had significantly negative effects on farmers，credit constraints；in the case of credit，loan conditions and violations had positive impacts on farmers’credit constraints， mortgage situation results had a negative impact on farmers’ credit constraints. On this basis，the paper did OLS regression by the data of obtaining full credit loans farmers，the estimated gap of credit demand was 5 169.4 Yuan， credit constrained ratio was 16.87%.
