| 摘 要： | 本文提出了非平稳社会经济系统建模的新方法——二步预测校正法,给出了该方法对于经济系统建模的应用。大量计算实例以及与逐步回归的比较表明,该方法不失为非平稳系统建模的一种有效方法,在样本容量较小时也能取得较为满意的结果。

| Abstract: | In this paper a new method of nonstationary socio-economic system model- ling,the two-step prediction-correction method,is developed.The method is applied to establish a regional economic system model.A great number of calculations and the comparison with the stepwise regression mncthod show that it is an useful method for nonstationary system modelling and can also obtain rather satisfactory results in case of smaller sample size. |
