#### Abstract

This paper focuses on the quantitative evaluation of enterprise credit risk and the comprehensive problem of bank’s decision on enterprise credit strategy under the background of big data.Firstly,the discrete credit rating is used to evaluate the enterprise’s reputation,and the standardized inbound and outbound sales are used to construct the index.The obtained evaluation matrix is used to evaluate the upstream and downstream influence of the enterprise by entropy weight method and TOPSIS model,and the effective vote ratio is used to evaluate the enterprise’s strength.Then,the three first-level indicators are used logistic regression,and the 0-1 variable U is used as the predictive variable to get the risk indicator of whether each enterprise will default.Then,nonlinear programming is adopted to solve the problem,and the monte Carlo method is used to simulate the solution with the objective function of maximizing the total income of the bank.By limiting the mean value of random number sequence,monte Carlo method is improved to improve the solving efficiency.Finally,the corresponding loan amount and interest rate of enterprises are obtained.
