    Abstract
    RESUMO O texto discute os processos de desconcentração das atividades produtivas da Região Metropolitana de Porto Alegre (RMPA), buscando investigar variáveis implicadas na emergência de novas centralidades e suas interações com os deslocamentos moradia-trabalho. Adota-se uma análise multivariável relacionando processos de conurbação e dados censitários de comutação às propriedades morfológicas da configuração espacial, descritas pela metodologia da Sintaxe Espacial. Através da Sintaxe Espacial, principal metodologia utilizada, identificam- se tendências de potenciais de movimentos e probabilidade de fluxos na rede metropolitana. Verificou-se na pesquisa: (i) intensidade e sentido de movimentos pendulares; (ii) hierarquias de acessibilidade relativa/ integração do sistema espacial; (iii) hierarquias de centralidade na rede de circulação/rotas com maior probabilidade de fluxo. Presume-se que há relação entre a desconcentração de atividades econômicas, as mudanças nos padrões de acessibilidade relativa regional, a emergência de centralidades funcionais e o sentido de fluxos pendulares metropolitanos ABSTRACT The article discusses the process of deconcentration of productive activities in the Metropolitan Region of Porto Alegre (Brazil) in order to investigate variables implicated in the emergence of new centralities and their interactions with commutation (home-work displacements). By adopting a multivariate analysis, conurbation processes and commutation census data were related to the morphological properties of the spatial configuration, described by the Spatial Syntax methodology. Through Spatial Syntax, which is the main methodology used, trends of movement potentials and probability of flows in the metropolitan network are identified. The following was verified: (i) intensity and direction of commutation flows; (ii) hierarchies of relative accessibility/integration of the system; (iii) centrality hierarchies in the network/routes with higher probability of flow. It is assumed that there is a relation between the deconcentration of economic activities, changes in regional accessibility patterns, the emergence of functional centralities, density and direction of metropolitan commuting flows.
