There are two major aspects for farmers to borrow money: the formal credit and informal credit. According to 897 questionnaire data about credit needs assessment of farmers from Shaanxi Province and Gansu Province, we find that farmers prefer the informal credit. On the basis, the paper studies the factors farmers consider when they borrow money from the formal credit. Then the results show that reasons leading to the phenomenon include the mistrust of banks, farmers dislike the way of loans, the complicated procedures, interest rate factors, farmer’ subjective preferences to the relatives and friends and so on. At last, the paper puts forward policy recommendations to solve the issue.
