Three methodologies were used: the first was the one of identification of APL through the location indexes and specialization of productive activities. The second consisted in job at gravitational model to identify and to hierarchy the economical polarity in center State and, the third, allowed to build the isopotenciais lines defining the reach at dominance of the poles on their influence areas, or outlying areas. The data used in the researches were coming of the Annual Relationship of Social Information – RAIS that systematizes the base of data of formal job in Brazil, for municipal district units of federation units. Data of Gross domestic product (GDP) and Population of the Brazilian Institute of Geography and Statistics (IBGE). It happens in a range of municipal districts of the State productive gatherings with connections with the agribusiness, forest business, mineral resources, trade and services. Being verified that there is a positive correlation among APL with those characteristics and GDP of the municipal districts in that they happen, in other words, as larger the bonds among APL of a die link of the chain productive, more prosperous the economy of the municipal district. The obtained results showed that it exists in a range of municipal districts of the State productive arrangements that you/they present complementarity bonds in the productive chain, as livestock and animal agribusiness, forest exploration and wood and furniture, among others. The identified and nested poles were, in this order: Belém, Marabá, Santarém and Castanhal. The work still identified transitivity relationship among municipal districts polarized by Belém and Castanhal, like this being the movement of these in relation to the dominant poles will be established by the force of measured attraction by the Normalized Gravitational Index. The work contributes to formation of politics of regional development because it guides the contribution of resources in productive activities with wide capacity of generating effects multipliers of income and job. Besides, in the domain of the scientific knowledge, it proposes the construction of Gravitational Indexes Normalized that you/they provide more complete results in the determination and hierarchization of areas pole.Outros
