The productivity effects of polycentricity: A systematic analysis of urban regions in Europe.

We focus on the extent to which polycentric urban regions can substitute for the agglomeration economies provided by large cities. Building on an open‐source software tool that helps identifying polycentric developments in urban regions, we analyse the spatial structure (in terms of size, dispersion and polycentricity) of 94 regions across 34 European countries and link this to their level of total factor productivity. We find that both more polycentric regions and more dispersed regions are associated with lower productivity levels. [ABSTRACT FROM AUTHOR]
