江苏人口老龄化与养老金合理支出量化分析

Quantitative Analysis of China's Population Aging and Rational Expenditure of Age Pension

基于人口结构理论和柯布—道格拉斯生产函数构建相应数理模型,对江苏省人口老龄化程度与养老金支出水平进行了定量测算和分析,分析结果表明:由于城乡二元养老保障体系的存在,江苏省现实的养老金支出水平低于理论上的合理值,养老保障支出有待于提高。根据研究结果,结合江苏省的具体情况,提出相应政策建议,以完善当前的养老保障模式。

Based on the theory of demographic structure and Cobb-Douglas production function, a mathematical model is developed to measure age pension spending and population aging in Jiangsu province. The results are showed that due to the existing dual old-age security system between urban and rural areas, the actual provincial pension expenditure level is below the theoretical fair value, which calls for a necessary advancement. Suggestions on a corresponding policy are proposed to improve the old-age security system.
