A scientific and methodological approach to the classification of value-added chains in vegetable production

Abstract

The article examines the theoretical and methodological foundations for the classification of value-added chains (VAC) in vegetable production. It is established that existing approaches to the typologization of VAC, primarily developed based on industrial sectors, do not adequately account for the sector-specific characteristics of agri-food systems. A critical analysis of key scientific concepts is conducted - from M. Porter's value chain model to modern approaches to global value chains, including typologies of governance, structural configuration, and the degree of participant integration. Systemic limitations of existing classifications are identified, manifested in conflicts between levels of analysis, lack of sector specificity, static nature, and the absence of a stage-by-stage analysis of value-added formation. The necessity of developing a specialized classification approach is substantiated, taking into account the specific features of vegetable production, including product perishability, seasonality of production, and the fragmentation of producers.
