The decomposition of a linkage into minimal components is a central tool of analysis and synthesis of linkages. In this paper we prove that every pinned d-isostatic (minimally rigid) graph (grounded linkage) has a unique decomposition into minimal strongly connected components (in the sense of directed graphs), or equivalently intominimal pinned isostatic graphs, which we call d-Assur graphs. W...

This paper analyzes trade in East Asia and inter-industry linkages over the borders, i.e. spatial linkages, with use of the Asian international input-output tables. As a result of analysis, it was shown that intra-regional trade within the eight East Asian countries, the U.S and Japan has been driven by the intermediate goods trade. At the same time, intermediate goods, especially those of the ...

This paper examines the relationship between input-output linkages and industry agglomeration by combining the strength of spatial econometrics and the input-output model. This paper uses the location quotient as a measure of industrial agglomeration and regresses it on the intermediate demand variable, which is an important variable in the integrated econometric and input-output models. The na...
