The main objective of the study was to determine the importance of subsidies for operations and investment in pig farms of different economic size. A detailed analysis covered farms specializing in live pigs production that kept records under the Polish Farm Accountancy Data Network (FADN). The research shows that with the increase in the economic size of farms the importance of subsidies in financing operating activities is declines. Farms with a significant economic strength invest more but the proportion of subsidies to investments in this group of households is the smallest. Under the new financial perspective the focus is on the need to implement investments aimed at greater specialization, increasing the production of piglets and the scale of raising finishers in farms.
