| 摘 要： | 根据山东统计数据信息，以山东省农村居民收入支出为例，应用灰色系统理论建立农村住户人均收入和支出的时间（1999—2006年）序列模型，分析收入和支出的内在关系和变化趋势，给出了GM（1，1）模型的实现方法。通过对预测结果的检验，证明灰色GM（1，1）模型具有准确性高、拟合效果好的特点。

| Abstract: | According to statistics information of Shandong Province,income and expenditure of the ruralresidents as an example,the time series models(1999-2006) of the rural households' per capita income andexpenditure is built by grey system theory.The realized method of GM(1,1) model is given by the analysis ofthe internal revenue and expenditure trends and changes.The results of the forecasting tests proved that greyGM(1,1) prediction model has a high accuracy and fit the characteristics of good effect. |
