摘　　要：考虑了替代率、缴费率、人口结构、分年龄段死亡率、经济增速、财政补贴、工资水平、投资效益,引入收缴率、通货膨胀率等当今影响养老保险的活跃因素,建立了"城乡结合"的中国城乡基本养老保险收支跨期叠代模型,并在此基础上进行优化.通过仿真,探讨了替代率和缴费率的合理区间.Considering replacement rate, payment rate, population structure, sub-ages mortality, economic growth, financial subsidies, wage level, return on investment, this paper introduces the collection rate, inflation rate and other active factors which have impact on today＇s pension insurance and then establishes a long-term Chinese basic pension insurance iterative model combined with urban and rural area, based on which gives the optimiza- tion. Through simulation, this paper discusses the reasonable range of replacement rate and payment rate.

关 键 词：收支叠代模型 梯度模型 替代率 缴费率
