Tytuł	Struktury rolne i produktywność rolnictwa w Grupie Wyszehradzkiej
Title	Agricultural Structures and Productivity of Agriculture in the Visegrad Group
Słowa kluczowe	produktywność, rolnictwo, ziemia, praca, Grupa Wyszehradzka
Key words	productivity, agriculture, land, labor, Visegrad Group
Abstrakt	Głównym celem pracy było porównanie zróżnicowania struktury agrarnej oraz produktywności ziemi i pracy w krajach Grupy Wyszehradzkiej. Dodatkowo analizie poddano znaczenie Grupy Wyszehradzkiej w Unii Europejskiej w odniesieniu do wielkości produkcji wybranych ziemiopłodów oraz pogłowia i obsady bydła a także trzody chlewnej. Jak wynika z przeprowadzonych analiz, najwyższą spośród państw Grupy Wyszehradzkiej produktywnością ziemi odznaczały się w badanych latach Polska i Węgry (ponad 600 euro/ha UR), z kolei największą dynamiką wzrostu tej wielkości – Słowacja (niemal dwukrotny wzrost w latach 2010-2013). Biorąc pod uwagę produktywność pracy należy podkreślić, że największą wydajnością pracy charakteryzowały się gospodarstwa rolne w Czechach i na Słowacji.
Abstract	The main objective of the study was a comparative analysis of the diversity of the agrarian structure and the productivity of land and labour in the Visegrad Group countries. Additionally, the importance of the Visegrad Group in the European Union was analysed in relation to the size of the production of selected crops and livestock as well as the population and cast of cattle and pigs. According to the conducted analyses, the highest productivity of land among the countries of the Visegrad Group was shown in the years under study by Poland and Hungary (over EUR 600 / ha AL), while the highest dynamics of the growth rate of this parameter - by Slovakia (almost two-fold increase in 2010-2013). Taking into account labour productivity, it should be emphasized, that the greatest labour productivity characterized farms in the Czech Republic and Slovakia.
