The method comprises the following steps: acquiring trade data, market data and customer demands, and constructing a trade big data platform; processing the trade data and the market data based on a data processing algorithm to determine the weight of the trade data, and dividing the trade data into a plurality of trade databases; training a neural network model based on the plurality of trade databases, and outputting the neural network model when the accuracy of the neural network model is greater than an accuracy threshold to obtain a credit evaluation model; processing the trade data and the demands of the clients based on a credit assessment model to assess the demands of the clients and the expected transaction risk of each enterprise; processing the expected transaction risk and customer demands based on a risk decision-making algorithm to generate a plurality of auxiliary decision-making schemes; and displaying the intermediate information on the trade big data platform. According to the method, the accuracy and efficiency of credit risk decision making are improved.
