基于帕累托优化的基本养老金替代率测算

基本养老金合意替代率是指能使养老保险制度优化发展的养老金替代率,是从需求方面来衡量基本养老金替代率的数量指标。基本养老金潜在替代率是指在其它条件不变的情况下,基本养老保险体系所能提供的最大限度的养老金替代率,是从供给方面来衡量基本养老金替代率的数量指标。基本养老金实际替代率是在养老保险实际发展过程中形成的替代率。基本养老金替代率优化模型是三种养老金替代率对接。根据优化模型对三种养老金替代率做了测算,提出了基本养老金替代率优化发展的政策选择。

Counting the Substitution Rate of the Basic Pension Based on the Pareto Improvement Model

The desirable substitution rate of the basic pension refers to the basic substitution rate that makes the endowment insurance developing optimally,and it is a quantitative index from the demand aspect.The potential substitution rate of basic pension is maximum substitution rate that the endowment insurance system can provide,holding any other factors constant,which is a quantitative index from the supply aspect.The practical substitution rate of basic pension is the substitution rate formed in the endowment insurance process.The Pareto improvemental model on the substitution rate of basic pension is the fusion of these three basic substitution rates.Furthermore,this model provides a measuring of these substitution rates and gives the policy implications to optimize the basic substitution rate of basic pension.
