因素分析法是可以从数据上测量形成总指标的各经济因素变化对总指标差异影响程度的方法,一直为人们广泛采用。但该法必须遵守因素替代的顺序性、顺序替代的连环性及计算结果的假定性,即进行替代时,必须按照各因素的依存关系,按照主要因素在前次要因素在后或数量因素在前质量因素在后的次序顺序排列,并连环替代计算,所得的结果被假定为是正确的。笔者认为,这样计算值得商榷。从经济角度分析,存在各因素排序的困 The method of factor analysis is a method that can measure the impact of the changes of various economic factors that form the general indicator on the total index difference from the data and has been widely adopted by people. However, the law must comply with the order of substitution of the order, the continuity of the order of substitution and the presumption of the result of the calculation, that is to say, the substitution must be made according to the dependence of each factor, according to the main factor in the previous factor or later The former quality factors are arranged in the latter order, and the calculation is replaced by a series of substitutions. The results obtained are assumed to be correct. In my opinion, this calculation is questionable. From an economic point of view, there are all sorts of factors in the trap
