ABSTRACT
There are several methods for measuring the inter-sectorial linkages, in order to identify the key sectors of an economy. The authors appealed to the classical definitions of Rasmussen (1956) and Hirschman (1958) as well as to the poles of growth formulated by Myrdal (1957) and Perroux (1977). The objective is to identify the key sectors of an economy and to define and promote strategies for industrial development. The convergence of resources and investments in key sectors may allow a rapid growth of production and jobs, preventing those resources of being assigned to other sectors.
