(Title in Polish - 'Wspólna polityka rolna po 2013 - uzasadnienie, funkcje, kierunki rozwoju w kontekscie interesu polskiego rolnictwa'). This article is a contribution to the discussion about the future shape of the European Union's Common Agricultural Policy (CAP). It refers to the paper 'Common Agricultural Policy after 2013 - proposals of changes' published in Wies i Rolnictwo 2010/2 and it includes the author's own reflections on the future shape of CAP. The model of CAP after 2013 is crucial not only from the point of view of the agricultural sector, but also from the point of view of the entire Polish economy. The expectations of the Polish agricultural sector towards CAP in 2014-2020 are going to be determined by the level of assistance recorded in 2013, by the sector's modernization needs and ability to fulfil its function as a provider of public goods. The analysis conducted in the article proves that policy measures from both pillars of CAP have a fundamental meaning for Poland. The level of assistance, its common character and the preservation of equilibrium between direct support and pro-environmental and pro-modernization measures remain important.
