中国城镇职工社会统筹账户的支付能力研究

Solvency Research on Urban Employees’ Social Pooling Account in China

养老保险账户的支付能力影响养老保险制度的可持续性发展。通过建立我国养老保险制度改革前后社会统筹账户的缴费积累和养老金领取的精算模型,对不同收入水平职工社会统筹账户的支付能力进行比较研究。研究表明:改革后扩大的社会统筹账户不足以应对基础养老金水平的待遇变化,社会统筹账户的支付能力被削弱,支付缺口呈现扩大趋势。政府在采取有效遏制提早退休现象、逐步提高法定退休年龄等政策外,应加大财政补贴力度来增强社会统筹账户的支付能力。

Solvency of endowment insurance account effects the sustainable development of endowment insurance system. This paper makes a comparative study on social pooling account＇ s solvency of employees in different wage level before and after China＇ s endowment insurance system reform by constructing the actuarial model of payment accumulation and retirement pension payoff.

Besides the policies such as containing the phenomenon of early retirement and gradually raising the mandatory retirement age, the government should increase financial investment to strengthen the social pooling account＇ s solvency.
