Abstract
The determination of sectoral priorities in the national planning of developing countries as well as the effective allocation of development assistance necessitate an empirical identification of key sectors. It is the purpose of this paper to compile and present quantitative measures while keeping this object in view. In focusing on structural interdependence of production, the following four different methods based on input–output data could be used:
(1) comparison of intermediate transactions with total production and demand;
(2) adjustment of (1) to allow for indirect efects;
(3) determination of power of dispersion;
(4) triangulation.
