The current study aims to reveal the regional network cooperations - found primarily in the construction industry -, in particular in the Észak-Alföld Region. The study includes three main parts: after the industry analysis of the construction industry a short summary follows about the theoretical bases of today's business network cooperations, clustering, and such relationships especially among firms operating in the construction industry, and finally it is closed by a case study revealing the relationship network of a dominant construction company of the Észak-Alföld Region. The most important finding is that in Hungary clustering in the construction industry - that has already existed in several developed economies - has not started yet, however, networking - that can be the basis for the development of a construction industry cluster - has already began, and if it continues, it further increased the advantages already experienced.
