Second-rank cities are back on the academic scene, capturing the interest of scholars with their unexpected recent performance with respect to first-rank cities. Looking at the data on average urban GDP growth in 139 European cities since 1996, the relatively strong position of large cities (over 1.5 million inhabitants) on national growth coincides with the periods of fastest expansion, while at times of slowdown second-rank cities prevail. Especially in the recent period of economic downturn, second-rank cities have recorded annual GDP growth rates much less negative than those of capital cities; and in some European countries, like Austria and Germany, all cities have outperformed their capitals.
In explaining this phenomenon, linking urban dynamics to agglomeration theories seems the most interesting approach. However, merely to link agglomeration economies to urban size in order to interpret urban performance is neither convincing nor sufficient, and it calls for additional investigation into how agglomeration economies work. This volume claims that interpretation of the current dynamics in European urban systems - especially in the western part of Europe - would benefit from exploitation of the traditional concept of agglomeration economies. However, necessary for this purpose are more in-depth considerations on the nature, scope, intensity, and causes of agglomeration economies which do not relate their existence solely to urban size. And this is where the main challenge for scholars lies, in the interpretation of the missing link between agglomeration economies and urban dynamics. This book was originally published as a special issue of European Planning Studies.
