It has been claimed that Asia lags behind the rest of the world in the privatization of airports. At the same time, the air transport sector has been growing quickly and this has placed enormous pressure on airport infrastructure. This paper reviews the situation and finds that the private sector is involved extensively with new airports and the upgrading of existing airports in Asia. Although the models used to accommodate the private sector appear similar to those used elsewhere, governments in Asia have retained majority control in every case. Despite the fact that some governments say that efficiency is important to them, the most common and important motive in “privatization” in Asia is to mobilize a new source of finance. Airports remain high on the agenda of public policy. Governments are concerned about abuse of monopoly powers and they want to cross-subsidize regional airports, but they lack the institutional strengths to regulate effectively. By retaining majority control, however, governments risk losing the efficiency benefits of privatization. The paper explores the reasons why airports are such difficult cases to deal with and concludes that there is a greater need than ever to be able to compare the performances of airports.
