The analysis of multiplier decomposition allows the study of economic or environmental efficiency along the whole economic or environmental efficiency along the whole economic flow for each productive activity . However ,in linking these items, economic and environmental efficiency ,it is necessary to relate the environmental effects that each activity causes with the economic effects that each activity generates. To do this ,we relate the economic and environmental multipliers calculated in Eqs, 8,9 and 10. Table 4 in the Appendix incorporates the indicators that have been obtained by dividing the respective environmental effects with regard to the economic effects of each productive sector. The most inefficient activities can be observed,in boldface and shaded-in the sense of combining a greater backward linkage effect in the sense of combining a greater backward linkage effect. From this perspective ,the following conclusions can be drawn.
