序列投入产出表的研究

A Study of Input-Output Tables in Series

探讨如何根据离散的投入产出表生成逐年连续的投入产出表 ,即序列投入产出表的方法 ,以扩大静态投入产出理论的应用 .在对于基本 RAS法、二阶段 RAS法等进行了系统研究的基础上 ,提出了分块应用 RAS法 .该方法首先对于直接消耗系数矩阵 A按变化类型的不同分块 ,然后对于每块分别应用 RAS法 .按照本文中提出的方法进行比较 ,结果是分块 RAS法优于二阶段 RAS法 ,二阶段 RAS法优于基本

Discusses the formation of yearly input output table through a series of discrete input output tables in order to make use of the static input output theory. Based on a systematic study on the basic and 2 stage RAS, the procedure of blocked RAS application is put forward. In the procedure, the direct expense coefficient matrices A are first separated according to different types of changes into blocks, and RAS is applied to each block. Comparison of the 3 approaches shows that the blocked RAS behaves better than the other two, while the 2 stage RAS operates better than the one using basic RAS.
