Abstract:
From time to time, input–output model have been applied in estimating economic –environment linkages. However, these approaches concern to the regional/national environmental feedback effect only. On the other hand, the structure of interregional linkages have been a common topic of discussion inregional analysis; attention has been directed to problems of interregional feedback effects and the degree to which change originating in one region has capacity to influence activity levels in another region, in turn, will effectactivity back in the region of origin.
 
Rather than trying to get a handle on the various departures from interregional feedback effect or environmental feedback effect independently, this paperattempts to measure impacts of residuals generated by interregional economic activities. The paper presents the conceptual framework of the interregional input-output model in interregional economic impact analysis
