A Time Series Analysis of the Structure Inducing Industrial Waste in Japan Using Regional Input-Output Model

Abstract

This study aims to examine the relationship between regional economic structure and industrial waste discharge in Japan. The study employs regional input-output tables and statistics of solid waste from industrial sectors published by the Japanese government for years 1990, 1995 and 2000. The findings have revealed that livestock, construction and food industries were major sources of industrial waste in Japan. Furthermore, livestock and food industries showed increases in induced industrial waste and a decline in environmental efficiency. The results imply that measures on the reduction of industrial wastes should consider determinant factors of each industrial waste.
