摘要
以山西省阳泉地区为例.首先用灰关联分析了第一产业增加值等七种指标对地区生产总值的影响程度,然后用PCRA(主成分回归分析)分析了影响生产总值的五种指标的综合作用程度,再用回归模型得到了五种影响指标与地区生产总值的拟合方程,且拟合效果较好.
Take Yangquan area for example, first, the influence of seven indexes such as the value added value of the first industry was analyzed by using grey relation analysis, then, the principal component regression analysis was used to analyze the overall effect of the indicators affecting the total value product, in the end, the regression model is used to obtain the equation of the five kinds of influence indices and the regional production value, and the fitting effect is better.
