This article discusses the differences between incentives and forms of farmers’ collaboration in agrarian, industrial and post-industrial economies and introduces collaboration examples based on the concept of a two-sided network as a new phenomenon appropriate for the post-industrial era. During the last decade the concept of a two-sided network (market) has been utilised predominantly by ICT businesses, however, the authors believe it has potential to become a general theoretical background for the revision of cooperative movement goals and means relevant to a post-industrial economy.
