Environmental, social, and governance (ESG) factors are crucial in evaluating a company’s value. High ESG scores reflect ethical practices, social responsibility, and effective governance. This paper examines the impact of ESG criteria on firm value within the airline industry, focusing on their influence on operational efficiency, risk reduction, and financial performance. Using panel data analysis, the study evaluates ESG scores from 32 airline companies over the period of 2018–2023, with an explanatory power of 36.5%. The research explores how integrating environmental, social, and governance factors into strategic management can foster sustainable competitive advantage. It focuses on utilizing internal resources, meeting the needs of various interested parties, and balancing financial, social, and environmental performance. The findings indicate that while ESG practices enhance firm value through improved efficiency and risk management, they do not always lead to higher short-term firm value. Moreover, the study underscores the significance of governance in the airline industry, where robust governance structures can mitigate risks but may also increase costs. This research contributes to the literature by providing empirical evidence of the link between ESG performance and firm value in the airline industry, emphasizing the importance of integrating ESG principles into strategic management for long-term sustainability and financial success.

ESG metrics have become increasingly important in evaluating corporate sustainability and meeting regulatory expectations. Thus, it is essential to explore these elements for a clearer understanding. This study examined the environmental (E), social (S), and governance (G) scores across various sub-sectors of the energy industry. Using systems thinking and creating shared value (CSV) approaches, the research investigated whether ESG performance varies significantly among the sub-sectors and how changes in one pillar might influence the others. Data from 576 companies in the Thomson Reuters EIKON database were analyzed using ANOVA, correlation, and multiple regression. The results revealed distinct differences in the ESG scores among sub-sectors, with environmental and social practices often reinforcing each other. However, governance showed a weaker influence, highlighting the need for further research on governance frameworks to clarify the underlying reasons and to integrate better with other ESG pillars. The research has specific implications for strategic management and provided recommendations for further studies.

This study investigates how Environmental, Social, and Governance (ESG) scores and the Corporate Governance Index (CGI) jointly influence firm value in Türkiye. To address the contextual limitations of global ESG metrics, this study incorporates the CGI, a country-specific governance measure developed by Capital Markets Board of Türkiye, as a complementary indicator. Using panel data from 44 non-financial firms listed on the Istanbul Stock Exchange between 2019 and 2023, the study applies a random effects regression model with robust standard errors. The findings indicate that both ESG and CGI scores are positively and significantly associated with firm value, along with profitability (ROA), while financial leverage and liquidity (CR) show negative effects. The results underscore the strategic value of aligning sustainability performance with governance quality, particularly in emerging market contexts. This study contributes to the literature by providing empirical evidence for an integrated ESG–CGI framework and offers practical insights for corporate managers, investors, and policymakers.

As energy is vital in the sustainability of almost every part of daily life, energy security has become more crucial than ever before. One of the main threats to energy security is a possible disruption along the trade network, which jeopardizes the constant energy supply. The purpose of this research is to identify the relation ties between EU countries in order to clarify the characteristics of the network, such as its crucial actors, vulnerabilities, structural holes, etc., to help achieve some proposals for a more sustainable and secure energy supply. This will help identify the underlying causes of recurring energy crises in the EU and provide insight into developing management strategies for further studies. Following this purpose, we examined the trade network density to clarify typical characteristics of the network, applied degree centrality measures to identify the most central importer and exporter countries, and found the dominance and critical vulnerabilities of actors in the network by using domestic import data of the EU countries. Finally, we recommend some policies and management strategies according to the obtained results and previous literature for further discussion.

Bu çalışma, Türkiye demir-çelik sektöründe faaliyet gösteren firmaların değişen rekabet dinamiklerine uygun şekilde verebilecekleri stratejik yönelimleri, stratejik yönetim kuramları çerçevesinde bütünleşik bir şekilde incelemektedir. 2019-2023 dönemine ait sektörel veriler kullanılarak üretim gelirlerine dayalı Herfindahl-Hirschman Endeksi (HHI), Entropi Endeksi (EI) ve CR4-CR8 oranları hesaplanmıştır. Söz konusu yapıyı stratejik açıdan değerlendirmek amacıyla çalışmada Porter’ın Beş Güç Modeli ana temel olmak üzere, Kaynaklara Dayalı Görüş (RBV) ve Ansoff’un Büyüme Matrisi ile üç teorik bakış açısı çerçevelendirilmiştir. Buna ek olarak, Çevresel Belirsizlik, Dinamik Yetkinlikler ve Sürdürülebilirlik yaklaşımları tamamlayıcı niteliğinde entegre edilmiştir. Çalışmanın bulguları, Türkiye demir-çelik ana metal sanayinde 2019-2023 dönemi boyunca HHI değerlerinin ve CR4-CR8 oranlarının düşmekte olduğunu, öte yandan Entropi Endeksi’nin artmakta olduğunu göstermiştir. Yoğunlaşma koşullarının azaldığını ve pazar paylarının daha eşit dağıldığını gösteren bulgular, sektörde yapısal değişimlerin meydana geldiğine işaret etmektedir. Bu bağlamda Porter’ın modeli, düşük yoğunlaşmalı pazarlarda firmalara fiyat rekabeti yerine farklılaşma stratejilerini önermektedir. POSCO’nun çözüm odaklı pazarlama yaklaşımı ve SSAB’nin HYBRIT projesi gibi örnekler, söz konusu stratejilerin nasıl uygulandığını göstermektedir. RBV çerçevesinde, dijital altyapı, beşerî sermaye ve yenilik yönetimi gibi firma içi kaynaklar, sürdürülebilir rekabet üstünlüğünün temel unsurları olarak öne çıkmaktadır. ArcelorMittal’in XCarb™ platformu ve POSCO’nun örgütsel yapılanma revizyonları, iç kaynakların stratejik değerini yansıtan örneklerdir. Ansoff’un büyüme stratejileri kapsamında ise, altyapı yatırımlarının yoğun olduğu bölgelere yönelik ihracat ve müşterilerle kurulan teknik iş birliklerinin etkili uygulamalar olduğu anlaşılmaktadır. Analizin işaret ettiği çevresel belirsizliğe ise Dinamik Yetkinlikler Yaklaşımı, örgütsel çeviklik, yenilik kapasitesi ve öğrenme yeteneğinin vurgusu ile cevap vermektedir. Özetle, çalışma nicel analizleri stratejik yönetim kuramlarıyla bütünleştirerek dönüşüm sürecindeki bir sanayi kolunda firma davranışlarını kapsamlı biçimde açıklamakta, gelişmekte olan pazar bağlamında rekabet yapısı ile firma stratejileri arasındaki ilişkiye dair teorik boşlukların giderilmesine katkı sağlamakta ve uygulayıcılara yönelik somut öneriler sunmaktadır.
