Efficiency of Investments in Regional Airports in Poland

The article, based on the Data Envelopment Analysis (DEA) method, determined the efficiency of investments from the period of 2007-2013 in individual Polish airports. The applied DEA model was aimed at maximizing effects. The following variables were adopted in the model: 1 input (the total value of funds allocated for investments in 2007-2013) and 5 effects (increase in the number of passengers served, increase in airport operations (ATM), increase in the number of parking aprons, increase in the number of direct regular destinations, increase in the number of gates). 6 airports showed the efficiency of the investments. For other airports, according to the benchmarking idea, changes in the level of effects were proposed that could improve their efficiency.
