摘　　要：将品质变量引入经济预测模型中，给出了多次跳跃、间断式模型和具有多个转折点的系统趋势变化模型的一般表达式。Variables of quality are introduced and applied in the model to predict economy. Thereby, an expression formula is presented, indicating a model of tendency to be varied systematically that features a multiskipping, intermittent model having multi intersection points. Upon the above mentioned, the paper explains with actual examples that the introduction of quality variables have contributed a lot to the regression model prediction with high accuracy.

关 键 词：品质变量 回归分析 经济预测模型 量化法
