In this work we seek to understand the (socio)spatial transformations in the Municipality of Duque de Caxias (RJ) integrated to the joint action of diverse social subjects perceiving the municipality as an example of spatial interrelationships in some moments of the organization of capitalism in urban peripheries. We consider (social) subjects all those who interfere in the production of space – scientists/researchers, State/politicians, capital/capitalists and workers/residents, in addition to what was called subaltern subjects. The readings carried out do not end the search for theory (endless), but if we remain on this part of the path (RealityTheory-Reality) we miss the continuity of the path that is to reach the real transformed by the movement of the space-time dynamics itself. It s not about steps on a path. It is a game of Reality-Theory-Reality dialectical interactions, the latter representing the transformed reality, which, if achieved, requires an immediate return to theory and initial observations. For a long time, and perhaps even today, the municipality of Duque de Caxias was, or is still seen, as the outskirts of the municipality of Rio de Janeiro, whether in academic centers or in the reality of citizens. This distant periphery is often seen not only as a territorial limit, but also as a limit to their place in the world. But the interaction center and periphery has always occurred and continues to occur, adapting to the different moments of capitalism. In the current moment of capitalism and seeking to think about the center-periphery relationship not simply from differentiation, but from a new development framework in which integration, that is, a process of negative socialization through consumption, credit and indebtedness, even within a framework of increasing poverty. Duque de Caxias changes, is still going to change and this change brings him the greatest transformation he has ever gone through, the greatest disturbance and the greatest development.
