Along with geographical places, spatial flows are increasingly important. Manuel Castells argues that instead of the historically developed geographical approach (“space of place”), actual developments call for a “space of flows” approach. Nevertheless, the global change in the international economy is uneven, so geographical differentiation is much greater than ever . A complex spatial structure is on the rise, which Dicken refers to as “a mosaic of unevenness in a continuous state of flux”. Therefore, the global economy is much more of a multipolar system. With the rediscovery of space, international integrations and subnational, regional levels (regional and local economy) are increasingly important alongside the level of nations.
