Résumé
This article proposes an analytical framework for the agroecological transition process at the level of agrifood sectors, drawing on approaches from sustainability transition research (STR) and the economics of innovation.

A number of key functions were considered, such as learnings and cocreation of knowledge, market formation and supply development through contracts. The relevance of this analytical framework to our understanding of value chain dynamics was emphasised through a study of 28 value chain cases claiming to have differentiated practices related to agroecological principles;
