多因素指数计算方法之改进

摘要

This research focusses on the index system establishment of multi-factors which sets the factors of the same measurement in the same period in a fixed base period.A new formula for multi-factor index is put forward on the fact that the mutual influence among a few factors decides the absolute value of the absolute numerical value as a whole according to the changes of their own in the changes and the fact that ananalysis is made on the absolute value of the absolute numerical value in a whole change.The formula can exactly determine the method and the degree influencing every factor changing with out consideration of the influence among the factors of different measurement in the sameperiod.%本文对多因素指数体系编制采取了将同度量因素所属时期一律固定在基期。 而对于几个因素"共变影响"部分按各个因素其自身变化而影响总体变动的绝对数值的绝对值，所占各个因素自身变化而影响总体变动的绝对数值的绝对值总和的比重进行分解，然后归并到各个因素中去，这样编制的多因素指数新公式。它剔除了不同度量因素所属时期的影响，能真正精确地测定各个因素变动影响方法和影响程度。
