论增量共变指数体系的非科学性——兼论均值加权指数体系的科学性

A Study of the Non-scientific Characteristics of the Incremental Covariant Index with Reference to the Scientific Characteristics of the Mean-weighted Index System

作为经济指数分析方法之一的统计指数体系迄今未能在经济分析中发挥应有的作用,究其原因,指数体系分析方法的内在矛盾不能不说是一个重要的问题。指数分析方法在发展中产生了多套指数体系,但均未能有效解决相对数与绝对数分析的内在矛盾。目前广泛使用的"增量共变指数体系分析法"存在诸多不科学性,未能真正解决传统指数体系的内在矛盾。而以马埃指数为基础建立的"均值加权指数体系"能有效避免上述矛盾,应是最合适的指数分析体系。

As one of the economic index analytical methods, statistical index system, has so far failed to play its due role in economic analysis because of the internal contradiction in the analytical method of index system. Various sets of in- dex systems emerged in the evolution of index analytical methods, but they have not been able to effectively resolve the in- ternal contradiction in the analysis of relative number and absolute number. Presently, the widely used ＂incremental eovari- ant index system analytical method＂ is nonscientific to a large extent and eannot really resolve the internal contradiction in the traditional index system. By contrast, this study discovers, the ＂mean-weighted index system＂ based on Marshall-Edge- worth index can effectively avoid the contradiction mentioned above; hence the most appropriate index analysis system.
