Abstract: With the trend of increasingly longer life expectancy, the pension risks rise. Under the constraint of actuarial equilibrium in the life cycle of pension insurance, policy designs largely affect peoples livelihood and consumption in the postepidemic period. The results show that: longer life expectancy will exacerbate decline of the replacement rate of average social wage and increase the risk of pension security in the last years of life. Increasing the pension adjustment index of older retirees is one of the policy options to solve the problem. However, raising the adjustment level will raise the actuarial imbalance risk over the life cycle. It is difficult to solve the dilemma between raising the pension payment and maintaining the actuarial balance by raising the minimum number of years for contributions. Delaying retirement as well as linking the calculation and payment coefficient of individual account, life expectancy, and adjustment index can realize the Pareto improvement of raising the level of security and maintaining the actuarial balance.
