And they are of interest for all actors and observers, because they note a long-term trend of expansion of higher education accompanied by a continuous debate about its desirability and a perennial instability or dynamic of the structures whereby extent of homogeneity or diversity is constantly on the move through changes of the overall structure as well as through re-positioning of the individual institutions on the overall ‘map’ of higher education.
Over the years, however, first, the emphasis placed on issues of the shape and size of the higher education system varied substantially. Moreover, we observe considerable changes of views and controversies about the most desirable quantitative and structural developments. Finally, perceptions underwent continuous revisions as regards the driving forces affecting the patterns of the higher education systems.
The aim of this contribution is, first, after a brief overview of the key elements of shape and size, to sketch the major developmental trends. Second, an overview is provided of key concepts explaining the structural dynamics. Third, special
