According to the resource dependence theory, organisations draw upon interorganisational relationships to address the need for additional resources. The purpose of this study was to analyse whether sport clubs with serious resource problems regarding members, human resources (volunteers and coaches), infrastructure resources (sport facilities), or financial resources would be more likely to have a relationship with another non-profit sport club, a school, or a commercial sport provider. As previous research on interorganisational relationships has been mainly based on qualitative approaches, this study used quantitative data from sport club surveys in two Western European countries, Germany and Belgium (Flanders). The results of the correlation analyses showed that sport clubs in both countries experiencing serious problems regarding the availability of sport facilities were significantly more likely to have relationships with a school or a commercial sport provider. The study provided quantitative evidence that serious resource problems are correlated with interorganisational relationships.
