This article analyzes the concept of‘space of flows'(Castells) and proposes a new cognition of space in the information age, beyond the physical perspective, and related to the social, relationship and actor networks perspectives. Space of flows, as an interactive network, is characterized from four main features: rapid interaction, asymmetry, multi-dimension and complex networks. Furthermore, it consists of elements, medium, nodes and dominant system of flows. The authors suggest that space of flows will play an important role in the process of spatial construction in the information age.
