Bu çalışmanın amacı, 2006 ve 2012 yılları arasında 255 Türk firmasından oluşan bir örneklemde kurumsal çeşitlendirmenin firma değerine etkisini incelemektir. Regresyon sonuçlarına göre, çeşitlendirilmiş firmalar uzman firmalara kıyasla çeşitlendirme primiyle faaliyet göstermektedir. Bu bulguyu açıklamak amacıyla işletme gruplarıyla bağlantıların çeşitlendirme-değer ilişkisi üzerinde olası bir etkileşim etkisi araştırılmıştır. Analiz sonuçları, çeşitlendirme primi bulgusunun yalnızca işletme gruplarıyla bağlantılı olmayan firmalarda geçerli olduğunu ortaya koymaktadır. Bu sonuçlar grup şirketlerinin çeşitlendirmenin faydalarını elde ettiklerini ve firma düzeyinde ek bir çeşitlendirmeye ihtiyaç duymadıklarını göstermektedir.
The objective of this study is to investigate the impact of corporate diversification in a sample of 255 Turkish firms for the period between 2006 and 2012. Regression results indicate that diversified firms trade at a premium compared to single-segment firms. To explain this finding, we also investigate the possible moderating role of business group affiliation for the diversification-value relationship. Analysis results reveal that the diversification premium is confined to firms that are not affiliated with business groups. These results suggest that group members already capture the benefits of diversification without the need to diversify further at the firm level
