Whither a Theory of Inter-organisational Relations: A Burgeon Field of Research Between Conceptual Innovation and Fragmentation

This article discusses the potential emergence of a theory on inter-organisational relations (IOR). Although no dominant set of causal statements about IOR exists, which is traditionally associated with a theory, the literature has made substantial advancements in the last decade. The main aim of this contribution is to review the respective literature, portraying its merits and shortcomings. The article shows that a rich analytical repertoire of instruments for research exists but that scholarship struggles to make use of these advancements. The article argues that an IOR theory is on the horizon but the field needs to accept and better conceptualise phenomena which lay outside the traditional understanding of theory building.
