| 摘 要： | 对我国有关部门当前采用的物价指数计算模型进行评价，得出了该模型对基年的依赖性较强这一不足，然后改进了此模型得到新的物价指数数据，最后基于改进后的物价指数模型建立了灰色GM（1，1）模型对未来几个月的物价指数进行预测，得出了若干结论．

| Abstract: | We make an assessment of the price index model formulated by the relevant departments of the government, and draw a conclusion that the current model highly relies on the base year. Then, we ameliorate the model into a new one. On the basis of the new price index data obtained from the improved model, we make a GM （ 1,1 ） model with which we predict the price index in the coming months, and deduce some conclusions. |
