Does spatial agglomeration increase national growth? some evidence from Europe

Economic geographers and regional economists have long been concerned with the problems provoked by uneven regional development and the ways by which policy intervention may be able to reduce such inequalities. However, in recent years the traditional argument for seeking to secure a reduction in the spatial concentration of economic activity in particular regions has been questioned and in some cases it has been suggested that policies that try to reduce regional economic inequalities may even reduce national efficiency. This article examines the evidence for a link between growth in productivity and the degree of spatial agglomeration across the nations of Europe. In doing so it considers how spatial agglomeration should be measured and how the relationship between agglomeration and the growth of productivity can be modelled.
