Adjustment methods of national input-output tables for harmonized and consistent multi-regional input-output databases

Despite the fact that input–output (IO) tables form a central part of the System of National Accounts, each individual country's national IO table exhibits more or less different features and characteristics, reflecting the country's socioeconomic idiosyncrasies. Consequently, the compilers of a multi-regional input–output table (MRIOT) are advised to thoroughly examine the conceptual as well as methodological differences among countries in the estimation of basic statistics for national IO tables and, if necessary, to carry out pre-adjustment of these tables into a common format prior to the MRIOT compilation. The objective of this study is to provide a practical guide for harmonizing national IO tables to construct a consistent MRIOT, referring to the adjustment practices used by the Institute of Developing Economies, JETRO (IDE-JETRO) in compiling the Asian International Input–Output Table.

Towards the Compilation of a Consistent Asian International I-O Table--The Report of the General Survey on National I-O Tables--

This paper reports on the survey of the characteristic features of national input-output tables compiled by the member countries of the Asian International Input-Output Table project. In making any inter-regional tables, the presentation format of each constituent table has to be carefully studied in order to design a common adjustment rule. The survey was conducted in the period of 2003-04, with invaluable cooperation from each collaborating institution of the project. Some analytical findings are drawn from the survey results, such as the similarity between each national table and the Japanese table, the responsiveness to the 1993 SNA, and the major areas of conflict regarding the presentation format.
