Topicality. With increasing competition in world markets and the dominance of corporate value chains, there is a need to introduce a cooperative model of interaction of small producers. In Ukraine, the formation of cooperative value chains is a priority in agri-food markets, the development of which is based on the consolidation of resources and parity of entities of the individual and corporate sectors. The development of cooperative value chains will increase the competitiveness of small agricultural producers, which highlights the need for new research in this area.Aim and tasks. The purpose of the article is to develop scientific and applied principles of formation and regulation of cooperative value chains in the agri-food markets of Ukraine on the basis of a reproductive approach. The main objectives of the study: to establish the socio-economic preconditions of agrarian cooperation in Ukraine; identify current trends and functions of agricultural cooperatives in the development of the agricultural sector of the economy; substantiate the structure of an effective cooperative value chain and incentives for the state. Research methods: system approach, analytical generalizations, structural, index, comparative, graphic.Research results. The main problems of access of small agricultural producers to corporate market chains are considered, the logistical detachment of the subjects of the individual sector from the profitable links of finishing and distribution of products is established. Based on empirical research, the dominant direction of redistribution of value added in market chains in favor of large corporations and intermediaries has been determined. The authors substantiate the cooperative model of forming effective chains of the agri-food market, which include multifunctional cooperatives, a logistics center and retail stores.Conclusion. A set of measures of state support for the creation and development of cooperative value chains in the agri-food markets of Ukraine is proposed. The implementation of these measures is focused on ensuring the competitiveness of cooperative market chains and their ability to interact on a parity basis with corporate and intermediary chains. The scientific novelty of the study is to substantiate the scientific and applied principles of forming effective cooperative chains for a more objective redistribution of value added between the subjects of such chains, overcoming structural and price imbalances of the agri-food market for its reproductive development.
