There are several works dedicated to study the agroindustrial chains from a technoeconomic point of view. Hoewever, only a few are dedicated to investigate its politicalinstitutional dimension. This paper proposes an alternative theoretical approach, and a model of analyses, founded on the political dimension of the agribusiness systems and its perception as a continuous movement or orchestration of insterests among a series of heterogeneous stakeholders. In order to build this theoretical framework, the authors articulate contributions originated from: rural economy, contemporary sociology of organizations and the view of strategies as political constructed trajectories.
