The purpose of the article is to develop methodological provisions on performance evaluation of agrarian producers and their cooperative associations in production and supply chain on the basis of updated reproduction approach that is based on the use of net value added indicator. The research methodology is to conduct a critical analysis of existing scientific approaches to the assessment of value added; substantiate components of net value added; develop a structural scheme of methodological provisions in the duality of conceptual and methodological bases; substantiate a four-level system of estimating indicators using the net value added indicator; determine the possibilities and advantages of author’s methodological provisions. Results. The authors prove the expediency of using the net value added indicator to assess the efficiency of both production and supply chains, as well as producers and their cooperative formations that are non-profit organizations. The components of net value added, which include wages, profit, and specific expenses of business entities in terms of the parts of the production and supply chain, are substantiated. The authors proposed a structural scheme of methodological provisions that united the conceptual and methodological bases, defined the main principles of evaluation: objectivity and accuracy, systemacity and complexity, efficiency, purposefulness, the priority of economic interests of the state (macrolevel). A four-level system of indicators is developed for estimating volumes and dynamics of net value added, reproductive product profitability, the structure of net value added, the efficiency of material and labour resources use. Practical implications. Methodological provisions can be used by commodity producers and their associations to assess the efficiency of operation in the production and supply chain, justifying the feasibility of establishing a cooperative in the region. Also, the results of the analysis can be used by the state authorities during the definition of “gaps” in the chain and the justification of methods of selective regulation for its balanced development. Value/originality. Methodological provisions developed by the authors form the analytical foundation for making managerial decisions both at the micro level (producers, cooperatives) and meso and macro levels (regional and state authorities).
