Continuous efforts to predict what is the most likely development and importance of the agricultural sector are being made in the long-term perspective. To this end, EAA prediction models (SZU-P1 and SZU-P2) were constructed, and coupled with a model that describes the importance and linkages of the agricultural sector to other sectors within the national economy of the Czech Republic (HDP-1 model). The models described below can be used for measuring and simulation of impacts of the agricultural sector with downstream and upstream industries on the Czech GDP, but also monitoring flows and linkages of the total agri-food industry complex on the national economy.
