投入产出系数作用新探及其实证分析

A New Probe on the Functions of Input-Output Coefficients and Their Empirical Analysis

直接消耗系数是生产单位j总产出要直接消耗的i产品量,反映j产品部门与i产品部门的生产技术联系,是建立投入产出模型的最基本系数;分配系数是i产品部门分配(提供)给各个部门作生产使用和提供给社会最终使用的数量占该部门产品总量的比重。目前对这些系数的作用阐述得不够充分,文章进一步从行、列、行和、列和的角度探讨它们的作用,也探讨其它一些可以直接从投入产出表计算的系数的新作用,并用中国2002年投入产出表系数进行分析。

The direct consume coefficient states that produce unit j product needs i product. It reflecrs the connection of production and technique between the ith and the jth section. It is the most elementary coefficient for founding input - output model. The distribution coefficient is the proportion that i section provide to all other sections and to the final consumers. This paper explores their new functions from the row, row margin, column and column margin, and new functions of other coefficients. The paper also makes an empirical analysis based on input- output table （2002） of China.
