Passenger and cargo traffic at Incheon International Airport show upward trend since its opening. As well as Incheon International Airport has posted significant growth in various indices maintaining its outstanding status as a hub airport in Northeast Asia, a share of non-aero revenue shows increasing trend since 2007. Revenue which is the most frequent output measure of airport can be divided into aero and non-aero revenues. The objective of this study is to analyze whether there is improvement of operational efficiency and to determine the factors affecting operational efficiency of Incheon International Airport using Technique of Order Preference by Similarity to Ideal Solution method Since Data Envelopment Analysis which is frequently used to analyze effectiveness of infrastructure such as ports and airport gives only absolute measures and distance from the frontier so that it is not easy to measure how good the value relatively is. Revenue and costs are used as performance data for empirical analysis. It is found that there is self-improvement of Incheon International Airport because Korean government stops subsidy to Incheon Airport from 2008. It is found that there is improvement in operational efficiency of Incheon International Airport since its opening 2001. It looks as if there is improvement in aeronautical operation of Incheon International Airport. Also increases in non-aero revenue stimulate total revenue of the airport. However, there is no distinct evidence that there is improvement of operational efficiency of Incheon International Airport in terms of aero-revenue. Finally, it is found that Incheon international airport focuses on effectiveness by expanding business boundary rather than efficiency by increasing internal competitiveness. It is known that major airports in the world including Incheon International Airport try to reduce fees from airline company, cargo company, and passenger to increase traffic volume and competitiveness since there are fierce competition in airport industry, especially in Asia. This may be the reason why aero revenue does not contribute improvement of operational efficiency of Incheon International airport.
