A nonsurvey multiregional input-output estimation allowing cross-hauling: partitioning two regions into three or more parts

摘要

This paper describes a nonsurvey method for estimating multiregional trades without eliminating cross-hauling, when a national biregional input-output table is available. Domestic outflows are assigned by interpolating the biregional trades on the basis of the gravity ratio between the origin and the destinations, with parameters estimated from an earlier survey on interregional transactions. The method is then applied to evaluate multiregional industrial waste disposal and landfill attributed to consumption in the city of Nagoya. Three-regional input-output tables with and without cross-hauling are estimated by partitioning the biregional table between Aichi prefecture and the rest of Japan.
