连锁替代法是经济活动分析的常用方法。由于其分析结果会因替代顺序不同而不同,有时不能正确反映,影响指标变动的主次因素。本文提出“连锁替代全排列组合分析法”,可以较好地解决这个问题。一、“连锁替代全排列组合分析法”的公式推导“连锁替代全排列组合分析法”的基本原理和分析步骤是:
Chain substitution is a common method for economic activity analysis. Because the analysis results will vary according to the order of substitution, it may not be able to correctly reflect the primary and secondary factors that affect the index changes. This paper proposes a “chain substitution alternative permutation and combination analysis method” that can solve this problem better. 1. The basic principles and analysis steps for the derivation of the “combination substitution permutation and combination analysis method” are:
