CHANGES IN THE PRODUCTIVITY OF AGRICULTURE AFTER POLISH ACCESSION TO THE EUROPEAN UNION

Abstract

The article determines changes in agriculture productivity of individual Polish voivodeships in 2005-2012 based on the Malmquist Productivity Index. The model features the following variables: one effect (value of purchased agricultural products) and five inputs (area of agricultural land, number of people employed in agriculture, use of fertilizers, number of tractors, livestock). The study indicated that technological progress had a greater impact on the change in productivity of agriculture in Poland in the period after accession to the EU than changes in technical efficiency. Meanwhile, the highest average index of changes in MPI during the period was achieved by voivodeships: Dolnośląskie, Lubelskie, Pomorskie and Mazoweckie.
