Abstract

SOZA-AMIGO, SERGIO. INTERSECTORIAL RELATIONS IN MAGALLANES IN SEARCH OF ITS ECONOMIC STRUCTURE. Magallania [online]. 2008, vol.36, n.1, pp.79-102. ISSN 0718-2244.  http://dx.doi.org/10.4067/S0718-22442008000100007.

It has always been a recurring theme to be able to establish what the key areas of an economy are, especially under an environment of input-output analysis. This would be caused by two reasons, the first would be related to the leadership that one particular activity can have on the other, what is meant to be motivated by the possible impulse that a particular sector can give to the economic development of a particular area, and on the other side, due to the fact that the concept of branch “key” has been subject to disputes for being very broad and vague, since it depends on the perspective that addresses the issue at hand. This study allows for a multiple-angle hierarchically of the importance of economic activities in the Region of Magallanes and the Chilean Antarctic. In order to do that, input-output tables developed by the INE-Chile and MIDEPLAN are used, and which data refer to 1996. Firstly, a linkage analysis is presented, and various techniques are used for identification [Rasmussen (1956), Chenery and Watanabe (1958), Hazari (1970), Cella (1985), Sonis et al (1995), Dietzenbacher and van der Linden (1997) and Soza (2007)]. The answers are finally combined to obtain some synthetic indicators, which facilitate their interpretation as well as avoiding a profusion of results. Secondly, the sensible of technical coefficients is determined using the Schintke and Stäglin proposal (1988), which has identified the importance of a branch in terms of its elasticity, given the number of more sensible coefficients presented in columns as well as rows, and depending on the alteration of each of the separate factors and following Aroche4s approach, in the sense of using Graph Theory (1996; 2002 and 2005), influence fields for have been identified each activity After carrying out all of the above, and based on the main results achieved, the following step was the identification of those groups which generate evolvement in the region studied.
