Article explores the relationship between the agrarian structure of the EU countries and their economic and environmental productivity, which places it within the scope of the sustainable intensification of agriculture researches. The aim of the study is to verify the hypothesis about the positive impact of concentration of land in agriculture for its economic performance and negative on the environment. As a measure of the structure GINI coefficient of land concentration was used, as indicators of economic and environmental productivity, value of production per hectare of UAA and production value which caused emission of 1 kg of CO2 equivalent greenhouse gases. The existence of the correlation was examined using linear regression model. The results showed the lack of relationship between the concentration of land and its productivity, and a positive relationship between concentration and agriculture environmental productivity.
