Measuring airport production efficiency based on two-stage correlative DEA

This paper puts forward a two-stage correlative DEA model to measure airport production efficiency. The complicated production process of decision-making units is decomposed into two sub-processes. The correlative DEA model is used to evaluate the airport production efficiency by considering the co-relationship of sub-processes within the whole production process; an empirical study on 8 airports in Asia is conducted and it analyzes the factors influencing the airport inefficiency with Tobit regression mode. The results indicate two-stage correlative DEA model can give more information to improve the airport´s efficiency than one-stage DEA model.
