The research objective is to shed light on the structural adjustment process of farming enterprises in Switzerland. To this end, an analytical tool is developed which allows us to identify the most important influencing factors and to estimate in advance their effects on the structural adjustment process. The resulting structures will be compared with the relevant goals of the (agricultural) policy in order to draw conclusions about the effectiveness of the adjustment process. Using scenario techniques combined with an agent-based simulation, the influencing factors are varied to investigate alternative options like cooperation and collaboration strategies for improving the effectiveness with respect to the social, ecological and economic goals.
