To achieve development, an economy must undergo constant transformations that imply increasing complexity, both technological and in the productive structure; considering mainly those sectors that have a higher capacity to influence the productive activity. Starting from such idea, we compare the structural transformations in three economies, South Korea, Spain, and Mexico between 1980 and 2005 to construct indicators regarding their development processes. We employ a methodology that derives from the input-output model, specifically the use of the "Maps of Fields of Influence", which allow analyzing two aspects: first, the structure of interrelationships between sectors, as well as their changes over time; second, the direction of structural change, basically the role played by the exporting industries. The main result obtained is that the different paths of development vary greatly, according to the level of dependence on the external sector, but it is mainly determined by the different degrees of interrelation within the system of industries.

This article analyzes the intersectoral relationships that characterized the economic structures of three countries during the 1980s and the first half of the 2000s (Mexico, 2003; South Korea and Spain, 2005). The present article attempts to explain potential growth trajectories using structural sensitivity analysis and the important coefficients (IC) by tolerable limits (LT) methodology, elaborating a typology of intersectoral articulation in each economy based on the characteristics of the countries' respective productive structures. This typology also accounted for the article's approach to the structural changes registered in each economy. [ABSTRACT FROM AUTHOR]

The Input-Output model assumes that the technical coefficient matrix changes as an economic system develops, following either of two tendencies; one, the entries of the matrix shrink, due to increased efficiency on the production lines; two, they expand, while productivity gains concentrate in the use of factors. Further, the economic structure grows more complex, as industries become more tightly (vertically) integrated and the development process evolves. Both phenomena have seldom been analysed together, despite the apparent connections they may have with the evolution of economic structures and the development opportunities countries may face. This paper intends to examine the implications of these tendencies for the evolution of economic systems in regards to the dynamics the growth process may adopt. Two indicators are presented here useful to characterise such dynamics, later tested on the Mexican IO data. [ABSTRACT FROM AUTHOR]

Sectors in economic systems are interdependent because they trade goods that consuming sectors use as inputs; the relative values of those supply and demand links define economic structures. Industries play different roles depending on the relative number of connections they maintain with one another and on whether those links are preferably demands or supplies. On this regards, we extend a stochastic social structural model into the economic context. Further, we apply it to recent Greek data, analysing the role of different technological intensity sectors. We show that our results help to explain some structural features of this economy. [ABSTRACT FROM AUTHOR]
