The aim of this paper is to evaluate changes in the role of agribusiness in the Polish economy, the relationships between various spheres of agribusiness and its links with othersectors of the national economy. The research was conducted on the basis of the input-output tables for 2005, 2010, and 2015 published by Statistics Poland. The analysis also confirmed most of the relationships formulated so far between the agribusiness development path and the level of economic development of a given country. From 2005-2015, the share of agri-business in creating the gross value added of the Polish economy decreased, similarly as the role of internal turnover in the material supply of agriculture, while the food sector became the leading link in the agri-food sector. The agri-business sector also showed strong links with the other sectors of the economy. The changes in the food economy were caused by the intensified relations of this sector with the other countries, which translated into benefits from the international division of labor.
