At present，small and medium-sized enterprises are facing more difficulties and greater pressure. This paper aims to study the  relationship between entrepreneurs’education level and enterprises’financing  decision utility，conduct optimization analysis based on the theoretical framework of probability distribution，simulate the two-way selection relationship between entrepreneurs and financing institutions，and deeply analyze  the nonlinear relationship between entrepreneurs’education level and enterprises’financing decision utility. It is found that a certain level of education can maximize the utility of  financing decision，but behavioral decision  should not be too risky，and the utility of  financing decision is restricted by risk preference，institutional lending limit and loan interest rate. This paper empirically tests that a higher level of education can promote the positive  effect of financing capability，provides reference suggestions for improving the situation of enterprise operation  and solutions to alleviate the problem of enterprise financing difficulties.
