| Abstract(English) |
Formation of airlines' strategic alliances is driven by the severe competition in air transportindustry. Although strategies are perceived as the weapons for anti-competitive tools amongmembers and, also coming up with several advantages, some risks are still existed. Accordingly,this study focuses on the effect of global air alliance membership on productivity comparisonwhich could explain about the long run growth. Translog Transformation Function is used to compare outputs, inputs, and productivity betweentwo alliance airlines and three non-alliance airlines. Outputs are classified into fivecategories which are scheduled passenger kilometers, scheduled freight ton kilometers,scheduled mail ton kilometers, non-scheduled ton kilometers and other operating outputs. Inputsare classified into five categories which are labour, fuel, flight equipment, ground propertyand other materials. The empirical finding indicates that all alliance airlines have better output comparison, butpoorer input comparison. This results from cooperative policies for output expansion such asfrequent flyer programs, codesharing and etc, while strategies for resource sharing and costreduction benefit limitedly because of several constraints. Also, alliance activities causeunavoidable burdens for members. As a whole, although alliance airlines do not have higherproductivity comparison than all non-alliance airlines, alliance still offers some benefitsthat improve output comparison which is an essential part of productivity improvement. |
