关于结构分解技术中两种分解方法的比较研究

Comparative Research of Two Decomposition Methods in Structural Decomposition Analysis

投入产出技术中的结构分解技术被广泛的应用于经济系统的各个领域,但随着不同的经济分析的需要,发现传统的结构分解方法——算术分解法在分析效率、强度等指数型指标时存在一定的分解困难。因此,本文提出了广义指数分解方法的基本概念和一般解,通过模型建立、以及我国生产能源消耗量的实证分析,对两种分解方法进行比较。研究表明,两种分解方法适用不同的指标形式,广义指数分解法在分析指数型指标时,更具优势。

Structural decomposition analysis（SDA） of input-output technique is extensively applied to many areas in economic system.However,with the different demands of economic analysis,the arithmetic decomposition method,which is the traditional structure decomposition method,cannot analyze the index easily,such as efficiency and intensity.This paper induces the basic concept and general solution of general exponential decomposition（GED） method.For comparing the two decomposition methods,it models and researches the energy consumption in production.The result is that the two methods fit to decompose different kinds of indicators,and GED is better to analyze the index.
