A TYPOLOGY OF PROPAGATION OF CHANGES ON THE STRUCTURE OF A MULTIREGIONAL ECONOMIC-SYSTEM - THE CASE OF THE EUROPEAN-UNION, 1975-1985

The effects of structural change in all sectors of some regions in mul tiregional input-output systems are explored in this paper. For each r egion, the changes in direct inputs are decomposed into a matrix of in traregional changes and a matrix of interregional backward linkage cha nges. This distinction provides for a decomposition of changes in the Leontief inverse into a sum of matrices representing the matrices of i ntraregional and interregional fields of influence of changes. In turn , this process facilitates the identification of changes in gross outp uts that may be traced to changes in intra- and interregional structur al changes. The analysis is applied to;he European input-output tables for 1975 and 1985.
