In turn, the purpose of the work is to find whether those processes were an objective phenomenon resulting from the level of development of production forces or — to the contrary — whether they were a consequence of administrative and political decisions made by central economic authorities and typical for a centralized, nonparametric system of management. The article is divided into two parts: theoretical and empirical. In the first part the author presents the object and purpose of concentration and centralization of land in agriculture. In the second part she points out to the stages and sources of concentration, déconcentration and centralization of land. In concluding remarks the author proves that the process of concentration did not influence the improvement of the efficiency of production expressed in terms of increased final production and increased production per 1 ha of arable land. To the contrary, the author also indicates that concentration and centralization are objective processes, and that they are an effect, not a cause, influencing the level of development of production forces in agriculture. Therefore, exhorting the concentration, especially in the state sector, brings about many consequences not only of economic but also of social and political character. Economic praxis have demonstrated that some administrative decisions in that sphere, especially those issued in the '70, have weakened the alliance between farmers and workers.polinfo:eu-repo/semantics/openAccessArtykuł
