在经济增长中制造业增长是重要组成部分，影响制造业经济增长的因素很多，在分析时常用多元回归分析方法，但有时建立的回归模型拟合效果不好或不合理。为此文中利用多元统计分析方法中的主坐标分析方法，给出无多重共线性的一组互不相关的主坐标，然后建立趋势面回归预测模型。文中建立了苏州制造业经济增长预测模型，实例表明效果很好。

Manufacturing is an important part of economic growth. Many factors take effect in the economic growth of manufacturing. Multiple regression analysis is often used, but sometimes the results are not satisfactory or reasonable. Therefore, we have adopted principal coordinate analysis in multiple statistics analysis, providing a set of disrelated principal coordinate without multicollinearity and established a forecasting model of trend surface regress. Practical examples show that this forecasting model of economic growth in Suzhou manufacturing is very effective.
