本文运用可计算一般均衡模型，探讨了不同的公共养老金制度对经济福利、代际公平和代内公平的影响。除了2004年公共养老金改革的基准案例外，本文还考虑了两种替代性改革：通过消费税为基本养老金福利提供资金，以及取消与收入相关的养老金福利。模拟结果表明，即使仅对基本养老金进行消费税融资，即两项改革的结合，也可能不会改善整体经济福利，尽管它通过诱导资本形成来增加经济产出。
This paper uses a computable general equilibrium model with overlapping generations to explore the effects of different public pension schemes on economic welfare, and intergenerational and intragenerational equity. Besides the benchmark case based on the 2004 public pension reform, the present paper considers two alternative reforms: financing the basic pension benefit through a consumption tax, and eliminating the earnings-related pension benefit. The simulation results suggest that even the consumption-tax financing of only the basic pension, namely, the combination of both reforms, might not improve overall economic welfare, although it increases economic output by inducing capital formation.
