Tehlikeli Özellikler: Türkiye Süper Ligdeki Futbol Kulüplerinin Sağ Kalım Analizi

Avrupa futbolu toplu sporlar arasında en popüler olanıdır. En üst seviye ligde sağ kalmak kulüpler için hayati önem taşımaktadır. Bu çalışma, 1990’dan 2017’ye kadar olan veri setine tekrarlayan olaylarda sağ kalım modelini uygulayarak Türkiye Süper Ligindeki kulüplerin sağ kalımını etkileyen faktörleri incelemektir. Çalışmanın en önemli sonucu ligde yeni olmanın yükümlülüklerinin bulunmasıdır. Yeni kulüpler var olan kulüplere göre ligden düşme konusunda daha yüksek bir risk ile karşılaşırlar. Takımların Süper Ligdeki ilk yılında küme düşme riski ligde var olan takımlardan 20.7 kat daha fazladır. Bu nedenle, Süper Lige yeni çıkan takımlar yeni olmanın cezasını çekmektedirler. Bunun haricinde, her bir yıllık tecrübe artışı risk oranını %10 azaltmaktadır. Bununla beraber, her bir yabancı oyuncu riski azaltırken, kulüp tarihindeki daha önceki her bir küme düşme sayısı riski artırmaktadır. Son olarak, kulüp merkezinin bölgesel konumunun ve aynı şehirde başka kulüplerin varlığının Türkiye Süper Ligde sağ kalım üzerinde anlamlı bir etkisi yoktur.

Hazardous Attributes: Survival Analysis of Soccer Clubs in Turkish Super League

European football is the most popular sports among the ball sports. Survival in the top-tier league is vital for the clubs. This study analyzed the factors that effected the survival of the clubs in Turkish Super League by employing a survival analysis for recurrent event model on the data set from 1990 to 2017. The most important finding was the existence of the liability of newness. The risk of relegation for the teams in their first year in the Super League was 20.7 times higher than existing teams. The new teams in the Super League suffered from being fresh to the league. New teams faced a higher risk of relegation than older ones. Other than that, the number of prior relegations in the club history increased the risk, while each additional foreign player decreased the risk. In addition, each year of experience decreased the hazard ratio by 10%. Briefly, regional location of the club base and existence of another team in the same city did not have significant effects on their survival in Turkish Super League.
