Abstract

As the number of commuters and the distances of home-to-work travel have increased during the last decades this study extends existing research on how these changes influence the delineation of labour market regions. Based on a former study where we proposed a new approach for delineating functional labour market regions based on commuting flows, this paper focuses on the temporal stability of such delineations. Applying the graph theory for the years 1993 to 2014 the best delineations  should be identified and compared with each other.Then we will classify regions with a stable labour market as core labour markets, regions that sometimes form an own labour market but belong to one particular other labour market region otherwise as partial labour markets and regions which belong to different labour markets over time as overlapping areas.
