Influence of the liberalization of the air transport industry on configuration of the traffic in the airport network

摘要

The present article analyzes the air transport behavior of an airport network from the point of view of concentration / dispersion (higher / lower hierarchical differentiation) in a context of post-liberalization of air transport. As a case study, for the application of the analysis methodology, the case of Colombia is used, where liberalization of the aviation industry began in 1991. During the study period, 1992-2014, the most important airports were privatized, there was a release of air fares, and new air operators entered the market. The most important results of the present investigation indicate a situation of concentration of the connectivity in a few nodes (airports) of the network.
