In 223, the pension will be adjusted by 7% for 3, yuan, 5% for 4, yuan and 3% for 5, yuan. The benefits of this adjustment are self-evident, which can effectively narrow the pension income gap, especially for enterprise retirees with pensions below 3, yuan and retirees with flexible employment, who can enjoy higher increase. But then again, there are still some disadvantages, and the disadvantages outweigh the advantages on the whole. (1) Violating the incentive function of endowment insurance. The purpose of old-age insurance is to pay more for a long time and pay more for more. In pension accounting, it is reflected in the basic pension, transitional pension and personal account pension. In pension adjustment, it is reflected in the adjustment of pension level and seniority. If the "lower limit and higher limit" of pension comes true, no one wants to overpay and pay the old-age insurance for a long time, which will cause the social security fund to fail to make ends meet. (2) Violating the adjustment requirements of the Ministry of Human Resources and Social Security. It was clearly mentioned in the notice of pension adjustment of the Ministry of Human Resources and Social Security in 222 that the linked adjustment should reflect the incentive mechanism of overpayment and overpayment, and should be linked to the payment period of retirees and the basic pension level. Therefore, the pension adjustment "lowering the ceiling" violates the adjustment requirements of the Ministry of Human Resources and Social Security, and the possibility of realization is slim. (3) Increase the risk of pension payment. Pensions are 3, yuan, 4, yuan, 5, yuan and distributed in a pyramid. Among them, retirees with pensions of 3, yuan or less account for the majority, and the higher the pension, the smaller the proportion. If the pension is lower, but the adjustment range is higher, the total amount of pension increase will be higher. In addition, the number of retirees born in 1962 and later will increase explosively, which will increase the payment burden of the social security fund and quickly exhaust the fund balance, which is not conducive to the sustainable development of the old-age insurance system. The above is the pension adjustment in 223, with 3, yuan up by 7%, 4, yuan up by 5% and 5, yuan up by 3%. Feasibility analysis.
