A Concentration Analysis In The Turkish Domestic Air Transporation Industry Using With CRm and Herfindahl-Hirschman Indexes

摘要

Concentration means that economic activities is dominated or owned by a small number of firms in any market. Accordingly, there is a negative relationship between concentration ratio in the market and level of competition. In other words, as the concentration rate increases, level of competition decreases and vice-versa. The low market concentration ratio and imperfect competition is a common occurence in the emerging countries such as Turkey. In this study, concentration ratio and level of competition of the top four airports in Turkey will be examined. In this context, the airlines' (using these top four airports) number of passengers and cargo volumes in 2013 will be used to analyse. For this purpose, the relationship between domestic air transportation concentration ratio and market structure will try to demonstrate with using M-Firm Concentration Ratio(CRm) and Herfindahl-Hirschman Index (HHI) Analysis methods. After the analysis, our results justified that market structure is far from competition. In addition, there are recommendations and determinations to what to do for ensuring competition and maintaining it truly in this study.
