The paper proved, on theoretical grounds, that direct support scheme induces changes in the volume and structure of goods production in relation to production generated by market operations, thus having a reallocation function. Using the constructed model, the paper graphically presents the impact of applying individual instruments co-creating direct support scheme (area payments, production support and historical payments) on the level of land involvement in agricultural activity and agricultural production volume. This analysis was supplemented with a description of the impact of individual forms of aid on the structure of agricultural production.
