| 摘 要： | 建立了一个用一串ＢＰ网络组成的、用于地区主要经济指标预测的人工神经网络系统，给出了该模型在两个地区应用中得出的不同结果；在分析这两种预测结果的基础上讨论了预测模型中输入输出指标变化对预测结果的影响．说明在神经网络预测模型中，输入输出指标的选择起着不可忽视的作用．

| Abstract: | A neural network system is provided to forecast major economic indexes of a region, which is composed of a series of BP neural networks. Based on the analysis of the different forecasting results of the two regions by the same neural network forecasting model, the effect of the changes of input and output index to forecasting results is discussed. |
