  1. Note: The benchmark assumption is clearly described in the third part of this paper. The payment base here is 0.5% higher than the assumption, namely 7.5% in the year from 2015 to 2020. The growth rate decreased by 0.5% every 5 years until to 2%. The bank interest rate is 0.5% higher than the assumption, namely 3%. The new retirement age scheme regulates that the retirement age is delayed by 4 months every year until the retirement age reaches 65. The individual account simulates the financial operation of pension fund in the situation of funding the individual account. “Earlier retirement” stimulates the employee retiring 3 years ahead of than the expected (statutory) retirement age
