OECD ÜLKELERİ TURİZM SEKTÖRÜNÜN EKONOMİK ETKİNLİK ANALİZİ: VZA İLE AMPRİK BİR UYGULAMA

Bu çalışmada, 2011-2015 yıllarına ait verilerle OECD ülkelerinin turizm etkinliğinin iktisadi analizi yapılmaya çalışılmıştır. Çalışmada, girdi değişkeni olarak gelen yolcu sayısı, turizm harcamaları, lojistik performans endeksi; çıktı değişkeni olarak da turizm gelirleri olmak üzere toplam dört değişken kullanılmıştır. Veriler, Dünya Bankası veri tabanından elde edilmiştir. Analiz yöntemi olarak, statik ve dinamik Veri Zarflama Analizi (VZA)’nin çıktıya yönelik modelleri kullanılmıştır. Analiz neticesinde; ABD, Avustralya, İspanya, Lüksemburg, Portekiz, Türkiye ve Yeni Zelanda’nın hem CCR hem de BCC çıktı yönelimli model sonucunda tüm yıllarda etkin ülkeler olduğu gözlenmiştir. Etkin olmayan ülkelerin değişkenler bazında yapmaları gereken iyileştirme değerleri incelendiğinde; turizm harcamalarının yaklaşık %2 azaltılması ve turizm gelirlerinin de yaklaşık %92 artırılması gerektiği ortaya çıkmıştır. Beş yıllık verilerin topluca değerlendirildiği dinamik analiz sonucunda CCR ve BCC çıktı yönelimli modele göre ABD, Avustralya, İspanya, Lüksemburg, Portekiz, Türkiye, Yeni Zelanda ve Yunanistan’ın etkin ülkeler olduğu gözlenmiştir.

ECONOMIC EFFICIENCY ANALYSIS OF TOURISM SECTOR IN OECD COUNTRIES: AN EMPRICAL STUDY WITH DEA

In this study we aim to analyze the efficiency of tourism potential of OECD countries in terms of economics perspective with the data of 2011-2015 years. Number of arrivals (NoA), tourism expenditures (TE) and logistic performance index (LPI) were used as input variables; while tourism revenues (TR) as output variables in accordance with the data acquired from World Bank (WB). Both statical and dynamic DEA were conducted with output oriented models. Considering the results of both the CCR ad BCC models as a whole; USA, Australia, Spain, Luxembourg, Portugal, Turkey and New Zealand were efficient countries in all years. Taking into account the required improvements of the variables of the inefficient countries, it is possible to say that tourism expenditure of the inefficient countries should be decreased approximately 2%. Moreover, it could be put forwarded that tourism revenues should be increased approximately 92%. As a result of a dynamic analysis, eight countries (USA, Australia, Spain, Luxembourg, Portugal, Turkey, New Zealand and Greece) were observed to be efficient DMUs according to both the CCR and BCC models.
