Summary: This thesis explores, in the case of European regions, industrial restructuring observed in the period 1985-1995 from a dual perspective, the organizational and planning. Based on a literature review which combines input from the space industry and the industrial economy, identifies the various aspects that they consider the vertical linkages between companies in the space. It then develops a theoretical model of strategic competition in the space in the productive sectors that are considered vertically related and studied their patterns of localization. Before discussing in detail the determinants of the changes noted, it conducts a descriptive analysis of the changing patterns of industrial specialization of the European regions and the degree of geographic concentration of the industry. Finally, an econometric analysis to determine whether changes in the organizational forms are related to changes in the patterns of localization and additionally analyze the effects of competition in space can have on the patterns of specialization and concentration. In the first case, there exists a function of costs to consider, from the technological point of view, the influence of patterns of specialization and concentration, along with other variables sectoral and regional authorities, the importance of vertical chains in the various sectors question. This chapter also relates to competition facing firms, not just locally but also with respect to companies located in other regions, the geographical concentration. The objective of this analysis lies in exploring the reasons suggested by the literature on the market power that can exert enterprises, and intermediate finalists, conducting exchanges with intermediate goods. The findings are twofold. On the one hand, the theoretical model allows to reveal the essence of competition in the space location decisions and the effects of these processes on the agglomeration or dispersal of economic activities. Moreover, the empirical results suggest the existence of economies of vertical disintegration in the territory for specific manufacturing sectors, as well as an important effect of competition on the local market power.

Summary: INDUSTRIAL AGGLOMERATIONS: THE SALMON INDUSTRY IN CHILE Summary In the last decades of the last century aquaculture experienced a remarkable expansion, with the animal production sector grew faster during that period. The global expansion of the production of salmon and trout contributed prominently Chile, which has quickly climbed to the top position as a producer. An outstanding feature of the production of salmon in Chile is that the industry was concentrated in a small space area, around Puerto Montt, in the Tenth Region of the country. Such concentration can not be explained in terms of natural advantages, and the thesis argues that responds to the forces described in the models Krugman and Venables (2005) and Venables (2006). The thesis is a descriptive analysis of the evolution of the salmon industry in Chile, in order to demonstrate that production phases can be found economies of scale, as well as provide evidence of the increasing variety of inputs completed. To analyze the evolution of the industry has resorted to two kinds of sources: first, a review of the literature related, especially in the field of aquaculture, and specifically with the characteristics of the salmon industry in Chile, and Secondly by conducting a survey of 20 experts, senior production companies salmon, food manufacturing, service and the organization of the sector. We have found significant evidence of the presence of economies of scale in the various echelons of the industry: companies feeding centers freshwater, especially sea water harvesting systems and processing plants and distribution business. Equally obvious is the gradual multiplication and specialization of the productive inputs employed by the industry.
