Purpose - This paper presents the results of an assessment of the aggregated competitiveness of the agri-food sector in EU member states. The authors sought answers to the following questions: What is the general level of competitiveness of the agri-food sector in the Community? Which countries are leaders in the EU and which are outsiders in this area? Research method - The analyses were based on a set of intentionally selected multi-criteria indicators and taxonomic methods. An aggregated Competitiveness Index (CI) was designed, which allowed evaluating and classifying EU countries into categories in terms of the studied phenomenon. The analysis draws upon data derived from the World Bank's and Eurostat statistical databases, and the assessment covered two years - 2004 and 2018. Results - The mean CI in 2018 for all the evaluated countries was 0.1701, while in the base year it was 0.1942, which means that in the analysed years the general competitiveness level of agri-food sectors in EU member states declined. Considering the possible range of CI (0.1), this level was very low in both analysed years. The general competitiveness level fell due to: reduced use of fertilisers, decrease in the relative export orientation, smaller area of arable land and a decline in employment in agriculture. Originality /value / implications /recommendations - The analysis of the agri-food sector presented in this paper, using a comprehensive index, is the approach that has not been previously applied, taking into account the selection of the components of a comprehensive index, which was made on the basis of the literature studies. The proposed index allowed classifying the countries of the European Union according to both their resources and performance in production and trade in the agri-food sector and comparing the position they occupied in 2004 and in 2018.
