産業構造変化の需要部門への波及効果評価のための新しいモデル式

産業連関表の応用

抄録

To evaluate the repercussion effect induced by the industrial structure changes, we propose a new model formula by introducing a demand-repercussion inverse-matrix which is different from the transposed matrix of Leontief one, but is rigorously formulated by applying the basics of the input-output table. The new formula is shown to be useful for the evaluation of repercussion on the demand sectors by exemplifying the specific calculations in which the added values in the sectors such as the metallic ores, pig iron and petroleum refinery products are varied. Introducing an artificial transformation for the amount of domestic product, the well-known model formula of a conventional price equilibrium model is derived and the meaning of the conventional model is discussed. Furthermore, we attempt to construct new input-output table which incorporates the repercussion effect of the variation of added value and we also present one of possible methods to adjust the whole industrial activities to conserve the gross domestic product.
