Evolutionary Game Analysis on the Phenomenon of National Student Loan Default

-In order to reveal the national student loan game dynamic evolution path and discuss how to guard against national student loan risk, this paper adopts the dynamic evolution game replication method to analyze the choice behavior between the bank groups and the student groups. The result shows that the staple reason causing the failure of cooperation between the bank groups and student groups is that the reward and penalties of relevant law are inadequate to the loan students or the interest to the banks from the loan is less than their opportunity cost. Government should improve the risk compensation mechanism of the banks and increase the reward and penalties to the students, which will make a win-win situation between banks and students and solve the phenomenon of the national student loan default effectively.
