Research On The Calculation And Solution Plans Of The Individual Account Gap Of The Employees’ Basic Pension Insurance

Since the introduction of the individual account system in China,it has been combined with the original pension insurance system and gradually evolved into the current "SP&IRA" basic pension insurance for employees.In particular,it is noted that in the background of deep aging in 2021,the long-term sustainability of the individual account of the employees’ basic pension insurance has been seriously challenged.Thus,this paper predicts and analyzes the difference between individual account income and expenditure and the gap in individual accounts,and then proposes solutions,and then analyzes the individual account gap based on the combination of different solutions to promote the improvement and development of China’s individual account system.The main research object of this paper is the gap in the individual account of the employees’ basic pension insurance,and the problem of balance of payments and gaps in individual accounts is explored by constructing an actuarial model.This paper first expounds the relevant concepts of individual accounts,then introduces the connotation and theoretical basis of individual account gaps,and summarizes the development process and status of the employees’ basic pension insurance individual account system in China,and then analyzes the causes of individual account gaps;secondly,predicts and analyzes the number of employees participating in the basic pension insurance contributions and retirements in 2021-2100 through the population transfer model;third,through the construction of individual account gap prediction model,The historical gap in individual accounts and the future balance of income and expenditure differences and gaps under different income schemes are calculated and analyzed;finally,the individual account gap resolution scheme is proposed,and the cross-effect of the three solution schemes is measured,so as to find a more comprehensive and feasible individual account gap resolution scheme.The research of this paper draws the following conclusions:(1)under the current system,the proportion of the elderly population has increased year by year,and the calculation results of the actuarial model support the conclusion that personal accounts will indeed produce gaps;(2)the solutions such as extending the retirement age,adjusting the monthly table and increasing the proportion of financial subsidies can indeed reduce the gap in personal accounts;(3)the size of the personal account gap under different solution schemes is not equal,and the extension of the retirement age,the adjustment of the monthly table,and the increase of the proportion of financial subsidies have a higher degree of mitigation of the personal account gap.The combination of different solutions can more effectively alleviate the payment pressure of personal account gaps.
