“…In the literature, it is possible to find many studies in different industries regarding the above-mentioned situations (market structure, demand, number of firms, etc.). Rhoades (1995), Hannan (1997), Kumar et al (2011) and Akomea and Adusei (2013) in the banking sector, Tatlı (2018) in the white goods sector, Akan (2012) in the manufacturing industry, Borenstein et al (1999), Pehlivanoğlu and Tekçe (2013) in energy industry, Blažková (2016) in food industry, Kaynak (2016) in clothing industry and Robinson (2011) in health industry, using concentration indices, they examined the relationship between market structure and variables such as price and profitability. Looking at the studies related to airline industry, one can also find studies investigating the market structure as well as studies on the relationship between market structure and price differentiation, entry and impact on competition (Abramowitz and Brown, 1993;Zhang and Round, 2009).…”

The aim of this research is to reveal the factors that determine the number of airlines at the airport and the demand for the market. In addition, another objective of the research is to reveal the market structure and the changes in the market structure using concentration measurement tools is another research purpose. The twenty-eight airports in Turkey were examined by panel data analysis between the years 2007-2018. Regarding the market structure in general, decreases have been observed in the concentration values over time. In other words, airports have become more competitive over time. The panel data results show that the number of airlines at airports is strongly influenced by the number of passengers in the relevant market, the city’s GDP, the number of university students, the number of visitors, and the hub airport. On the other hand, it is evident that the number of airline carriers operating in the relevant market, the city’s GDP, its population, the number of university students, the presence of a hub airport, and the number of tourists have a substantial impact on the demand at airports. Results obtained in this research will contribute to the literature by providing new models of market structure and demand. It is thought that the research will guide airline companies and airport managers in terms of predicting demand. Key Words: Airports, Panel Data, Air Travel Demand, Market Structure, Competition. JEL Classification: L11, L93, R41

The aim of this study CR N (CR 4 and CR 8), using the Herfindahl-Hirschman Index and the entropy is to analyze the degree of concentration of the Turkish clothing industry. Based on ISIC Rev.3 classification operating in Turkey first among the 500 largest industrial companies and garment manufacturing market, sales revenue of the companies were analyzed. Data set used in the study covers the period 1995-2014. According to the results of CR 4 analysis period the concentration was somestimes higher and sometimes lower. According to the analysis concentration ratio CR 8 , except 2002 and 2003, came always high, especially the global economic crisis has led to the sector move away from the industry's competitive structure. According to HHI analysis results the degree of concentration of firms operating in the clothing sector have taken place in the range of 468 to 1357, the low concentration levels until 2008, while after 2008 was found the concentration is moderate.

Bu çalışmanın amacı, bilgi ekonomisi çerçevesinde değerlendirilen internet servis sağlayıcıları piyasasına yönelik bir yoğunlaşma analizi gerçekleştirmektir. Yoğunlaşma analizi için n-firma yoğunlaşma oranı, Herfindahl-Hirschman Endesksi ve Entropi endeksi kullanılmıştır. Elde edilen bulgular, internet servis sağlayıcıları piyasasında yüksek düzeyde yoğunlaşmanın olduğunu göstermektedir. Bununla birlikte, bu piyasa için zamanla yoğunlaşma düzeyinde bir azalma eğilimi gözlenmektedir. Kısa dönemde olmasa da uzun dönemde, bu piyasada rekabet düzeyinde bir artış beklenmektedir.
