Urban spatial development is marked by diverging, sometimes contradictory developmental dynamics. Both within and between urban regions, mutually reinforcing as well as contradictory processes of concentration and deconcentration are occurring. From an economic perspective, two fundamental and empirically observable trends of urban spatial development are the metropolization of the global urban system (Kr├Ątke, 2007; Floriade et al., 2017), which has a spatially concentrating effect, and the regionalization of cities (Phelps 2004, Soja, 2015), which has a de-concentrating effect. At the same time, demographic processes of reurbanization (Brake and Herfert, 2012; Rerat, 2012) and suburbanization (Modarres and Kirby, 2010; Hierse et al., 2017) are taking place. These trends lead to both discontinuous and disparate processes of spatial concentration and deconcentration of demographic and economic activities (Scott, 2001). Numerous descriptions of these trends of urban spatial development, as well as of individual causal drivers, are to be found in the literature (for example, Brake and Herfert, 2012; Florida, 2012; Glaeser, 2011). But the debates on demographic and economic processes of concentration and deconcentration are frequently disciplinary in character and are conducted separately from each other. The paper aims to bring together and conceptually consolidate these theoretical debates that have hitherto been pursued separately of one another on my means of a qualitative impact model. This allows for a better causal understanding of processes of concentration and deconcentration in and between urban regions.
