Revisitando o conceito teórico de polarização, aglomeração e centralidade

Abstract

This essay aims to perform a theoretical survey of the main approaches of the regional economy concerning to theories of agglomeration, centrality, and polarization. They describe the dynamic mechanism of self-reinforcing resulting from externalities due to the agglomeration of industries. Therefore, an exploratory methodological tool was used and by way of literature. The polarization theory alludes to François Perroux and his approach is about motive power industry and growing center. The agglomeration theory of productive activities is resultant of the introduction of space in economic analysis. The centrality shows the organization and hierarchy of space, also features the formation pattern of the cities’ network and the specialization role of each of them. It is concluded that the main issue in the analysis regarding the revisited theories are inside the conflict element, because they tend to intensify inequalities and the exclusionary character of the production system, although propelling the increase income and employment in certain areas.
