Research on Comparative Analysis of Input-Output Table by Input-Output Coefficients and Sharing Coefficients

Abstract

Non-Survey Method is a method of indirectly estimating the input-output table in the region where the table is not prepared. This method is eventually to estimate the input-output table of a small region which is included in the large region of which input output table is available. The majority of Non Survey Methods which have been already proposed and researched use input output coefficient as an index which describes a industrial relationship. However, it has not been explained how tightthe relationships between input-output coefficients of the large region and the small regions are. In this study, input-output tables of a large region and small regions were compared in terms of their input-output coefficients and sharing coefficients. It were conducted for the input output tables in 1990 of the whole country, Kinki District, and four prefectures. The results of analyses admitted that the degree of correlation between input-output coefficients of these regions was high. On the other hand, the sharing coefficients which included in out flow (import, export, shipping in and out) did not show high correlation between these regions. However, the analyses excludingthe in-out flow showed very high correlation between these regions. From these analyses, it was understood that inner region flows in the large region might be the largest cause of this phenomena.
