Integration of Global Performance Indicators with Aggregation Techniques

Abstract

Evaluating country performance using a single index is often insufficient because these indices typically specialize in specific areas. This study aims to provide a more comprehensive assessment of country performances by using various indices together, including the Human Development Index (HDI), Environmental Performance Index (EPI), Global Innovation Index (GII), World Happiness Report (WHR), and World Justice Project Rule of Law Index (WJP RLI). Additionally, the results of these indices are aggregated using the Borda, Copeland, Dodgson, and RAT techniques, and the outcomes are compared. The study shows that the RAT technique provides more precise and consistent results compared to the other techniques. The RAT technique was able to rank all countries fully without assigning the same rank to multiple alternatives. In contrast, the Borda, Copeland, and Dodgson techniques faced difficulties in fully ranking the countries, often assigning the same rank to multiple countries. Nevertheless, a high degree of consistency was found among the rankings obtained with the used techniques. Considering country performances, Denmark, Finland, and Sweden demonstrate high performance, while Romania, Hungary, Bulgaria, and Montenegro show lower performance. Turkey generally ranks lower and needs improvements in various areas. The study emphasizes the importance of policy reforms, investments in education and health, environmental sustainability, and innovation.

Küresel Performans Göstergelerinin Toplulaştırma Teknikleri ile Entegrasyonu

Öz

Ülke performansını tek bir indeks kullanarak değerlendirmek, bu indekslerin genellikle belirli bir alanda uzmanlaşmış olması nedeniyle yetersiz kalmaktadır. Bu çalışmada, İnsani Gelişme İndeksi (İGE), Çevresel Performans İndeksi (ÇPE), Küresel İnovasyon İndeksi (KİE), Dünya Mutluluk Raporu (DMR) ve Dünya Adalet Projesi Hukukun Üstünlüğü İndeksi (DAP HÜE) gibi farklı indekslerin bir arada kullanılarak ülke performanslarının daha kapsamlı bir şekilde değerlendirilmesi amaçlanmaktadır. Ayrıca, bu indekslerin sonuçlarını toplulaştırmak için kullanılan Borda, Copeland, Dodgson ve RAT tekniklerinin sonuçları karşılaştırılmıştır. Çalışma, RAT tekniğinin diğer tekniklere göre daha kesin ve tutarlı sonuçlar verdiğini göstermektedir. RAT tekniği, tüm ülkeleri tam olarak sıralayabilmiş ve aynı sıraya birden fazla alternatif atamamıştır. Buna karşılık, Borda, Copeland ve Dodgson teknikleri bazı durumlarda aynı sıraya birden fazla ülke atayarak tam sıralama yapmada zorluk yaşamıştır. Bununla beraber kullanılan tekniklerle elde edilen sıralamalar arasında yüksek düzeyde tutarlılık olduğu belirlenmiştir. Ülke performansları dikkate alındığında, Danimarka, Finlandiya ve İsveç gibi ülkeler yüksek performans sergilerken, Romanya, Macaristan, Bulgaristan ve Karadağ daha düşük performans göstermektedir. Türkiye ise genel olarak alt sıralarda yer almakta ve çeşitli alanlarda iyileştirmelere ihtiyaç duymaktadır. Çalışma, politika reformları, eğitim ve sağlık yatırımları, çevresel sürdürülebilirlik ve yenilikçilik alanlarında yapılacak iyileştirmelerin önemini vurgulamaktadır.
