The European internal market has increased politicians' interest in th
e implications of the new international situation for public administr
ation. In particular, collaboration between regional and local authori
ties is regarded as important in order to accomplish economies of scal
e and scope. In this context, the Euregion Maas-Rhine - an area consis
ting of five regions in three nations, encompassing three languages -
is a peculiar and complex example. Using network ideas as a theoretica
l framework, this paper describes and analyzes attempts to generate co
llaboration in this region. It highlights various recommendations for
the practice of transborder interorganizational cooperation and consid
ers the implications for the further development of network theory, a
branch of organization theory which is becoming increasingly important
for both business and public administration.
