The paper deals with problems of a PSE indicator. The aim is to delimit the EU position in the framework of selected OECD countries (countries of a comparable economic level). In this connection not only development tendency of this indicator is evaluated, but above all the attention is paid to the PSE structure. Further, the paper analyzes problems of the PSE in relation to incomes of agricultural producers and a profit of agricultural farms because the connection between these categories is considered significant. The methodology corresponds with set aims (a horizontal and vertical analysis, a comparison). Conclusions are presented in the sense: evaluation of development trends of the PSE, the PSE structure, suitability of the methodology of determination of indicators, analyses of the relation of the PSE, incomes and a profit.
