中国城镇养老保险制度改革的收入分配效应——基于2002年城镇住户调查数据的定量分析

The distributional effects of public pension reform in urban China

Using the micro data of Urban Household Survey made by the National Bureau of Statistics of China(NBS) in 2002, this paper studies quantitatively the distributional effects of Public Pension Reform in urban China, from intragenerational and intergenerational perspectives, by measuring lifetime net benefits that urban employees obtain under the public pension system in 1997 and the newest one announced in December 2005, respectively. The results indicate that the regressive income transfer existing before implementation of the reform is improved as a consequence of the 1997 reform. However, the Act of 2005 Reform generates the obvious inclination of the regressive income transfer among people who exceed 40 years old in 2002. On the other hand, from the viewpoint of intergenerational distribution, the intergenerational inequality resulted from 1997 reform is greater than that from 2005 reform. Moreover, all generations would receive higher lifetime net benefits under the Act of 2005 Reform, but it must be based on sustainable pension system and participants’ full pension contribution during their duration of employment. __________ Translated from Jingji yanjiu 经济研究(Economic Research Journal), 2007, (3): 70–80, 91
