Wydajność pracy i koncentracja produkcji w polskim przemyśle spożywczym na tle krajów UE-28
The aim of this study was to show changes in labor productivity and concentration of production in the Polish food industry against the background of European Union countries and the indication of the causes (factors) which caused these changes. Poland's accession to the European Union has proved beneficial for the development of the Polish food industry. The dynamic development of production in this sector after 2004 has been accompanied by improved labor productivity, which is one of the main determinants of a company's competitiveness in the market. The assessment of changes in labor productivity was made at current prices, as well as at comparable prices, taking into account the purchasing power of currencies of individual member states. The method of compound interest was used to determine the average annual changes. In the years 2004-2014, labor productivity measured by the value of sold production increased in the Polish food industry (in comparable prices) from 141.2 to 225.3 thousand Euro/employee and was only about 10 percentage points lower than the EU-28 average. Importantly, productivity growth has occurred, although to a varying extent, in all sectors of the food industry in Poland. In the analyzed period, the number of food processing enterprises decreased in most EU-28 countries and the concentration of food production increased. Such changes have occurred in the largest EU-28 food producers, to which Poland is also counted.
