PRICE DIFFERENTIATION OF AGRICULTURAL PRODUCTS IN POLAND – REGIONAL APPROACH

Abstract

The main aim of the research was to assess the price differences of selected agricultural products in the area of the first degree administrative division of Poland. The study focused on the analysis of the dynamics of price changes in individual regions, specified the impact of the production volume and consumption of a given product on the retail price, and an attempt was made to define a regression model in terms of the price of an agricultural product. The years 2010-2019 were assumed as the research period, and four products were analyzed: sugar, eggs, flour and milk. It was found that the average annual dynamics of changes was similar for all voivodeships, in particular for products such as flour, eggs and sugar. In the case of the correlation analysis, it was found that there was a certain interdependence of prices in relation to production and prices for consumption, which is not coherent on a regional basis. The regression model analysis proved ineffective in trying to forecast future market behavior as well as consumer behavior.
