Actuarial Evaluation of the Financial Backing Risk on Chinese Public Pension

Abstract

The Comprehensive Scheme on Reducing Social Insurance Contribution Rates (RSICR scheme) issued in 2019 had an important impact on the financial backing risk of the Chinese Public Pension for Enterprise Employees. We developed actuarial models for contribution revenues, benefit expenditures, and the balance of the public pension to analyze the impact of the RSICR scheme on the financial status of the Chinese Public Pension and the financial backing risk early warning after its implementation. This was done according to the State Council Documents and considering the interruption of participants’ contributions and the contribution salary being lower than the statistical salary. We found that (1) the RSICR scheme will worsen financial status in earlier years; however, it effectively slows down the trend of financial deterioration in most years of the forecasted period. (2) After implementing the RSICR scheme, four early warning indicators were selected and calculated. Since 2022, the financial backing risk of the Chinese Public Pension has increased rapidly, and four warning levels–blue, yellow, orange, and red–and their corresponding warning-year intervals were obtained. (3) According to sensitivity analyses, the key reverse early warning indicators’ influencing factors ranged from strong to weak: retirement age, firm contribution rate, and total fertility rate. In the same direction, from strong to weak, are the benefit growth rate, the bookkeeping interest rate, and the transitional coefficient. Finally, we propose policy suggestions to alleviate the financial backing risk. JEL Classification: G22, G23, H83, P34.
