| 摘 要： | 本文通过对中国人民银行公布的自１９９４年６月至１９９５年２月三年期以上定期储蓄存款保值贴补率进行研究，推导出其走势的数学模型为：Ｚ_ｔ＝Ｚ_（ｔ－１）＋Ｚ_（ｔ－１）＋Ｘ－０．３２９４ｘ_（ｔ－１）－０．２０７５ｘ_（ｔ－２）＋０．０５２９ｘ_（ｔ－３）＋ａ_ｔ并用此模型对１９９５年３月份的保值贴补率进行预测．得到预测精度为９５％的结果。

| Abstract: | ased on the studies of the Value-keeping subsidizing rate of the fixed deposits for over three years from June, 1994 to February,1995 issued by the People's Bank of China, this article infers that the mathematical model of the trend is as follows:Zt=Zt-1 Zt-1 X-0. 3294xt-1-0.2075xt-2 0.0529xt-3 at. We also use this model to predict the value-keeping subsidzing rate of March. 1995. the accuracy of which is 95%. |
