Statistical Decision Research of Long-Term Deposit Subscription in Banks Based on Decision Tree

摘要

It is particularly important to effectively mine potential customers and provide differentiated services for them to improve the competitiveness of banks with the strong competition among banks. This paper uses decision tree algorithm to analyze factors that affect whether bank customers subscribe to fixed deposits or not, and constructs a decision tree model of influencing factors of bank customers subscribe to fixed deposit business. The results show that the three factors that significantly affect customers' subscription for long-time deposits are the number of employees, duration and month, which greatly reduce the scope of customers that banks push to subscribe for long-term deposits, and are conducive to improving the efficiency of banks.
