This case study aims to analyse dyadic empirical relations within food supply chains. The categories of market, hierarchy or power, network and social relations were used to disclose the coordinative structures on the chain level and connect these with the chain development.
The actors of three vegetable supply chains were interviewed. The coordinative relations of actors were identified and the coordinative structures on the chain level were made visible by combining the ego networks of chain actors. The “story of supply chain development” was intertwined with the analysis.
The studied food supply chains were coordinated mostly by duplex or multiplex relations, combining market, hierarchy or power, network and social relations. In addition to the strategic network, presented in literature, the study identified a coordinative structural mode of socially overlaid network. In general, the network relation was found to be used as an effective “glue” within all coordinative structures. Both coordinative structural modes exhibited substantial growth, on the condition that agricultural base and buyers enabled enlargement.
Economic sociological perspective has been used in explaining food supply chain development by making visible the coordinative relations and structures on the chain level. The chain level phenomena appear as a promising field of study.
