摘要
养老保险筹资模式分为现收现付制和基金制。由于世界人口迅速老龄化,相对于现收现付制,基金制具有资本积累作用,能够促进经济增长和提高社会福利。通过构建一个把养老金资产作为转移因子的柯布——道格拉斯总量生产函数,并探讨养老基金资产对资本形成和经济增长的影响,可以见出:长期内我国现有的"部分基金制"的养老保险筹资模式促进了经济增长和资本形成,但是从短期看,部分基金制对二者没有显著的积极影响。
Pension funding model is divided into pay-as-you-go scheme and funding scheme.As the world＇s rapidly aging population trend,with regard to pay-as-you-go scheme,funding scheme has a role to accumulate capital,promote economic growth and improve social welfare.In the paper,a modified Cobb-Douglas production function with pension assets as a shift factor is designed,and the direct link between pension assets,capital formation and economic growth is investigated.The results show that our existing quasi-funding scheme can promote capital formation and economic growth within long-term,but it has no significant positive impact on capital formation and economic growth in short term.
