Assessing the localization pattern of German manufacturing and service industries : a distance based approach

This paper assesses the agglomeration pattern of four-digit industries in Germany using a rich data set on the population of German firms. To identify geographical agglomeration, we follow the distance based approach of Duranton and Overman (2005) and find that the location pattern of 78% of our industries departs from randomness in the sense that firms exhibit significant geographical localization. In line with previous studies on manufacturing firms in the UK and France, our analysis suggests that especially traditional manufacturing industries exhibit strong localization patterns. Moreover, we find that geographical localization is not restricted to the manufacturing sector but that it plays an equally, or even more important role in service industries. -- geographic concentration ; agglomeration
