Enerji, son yıllarda hem ekonomik hem de politik olarak dünya gündeminin önemli bir parçası olmuştur. 21. yüzyılda, iklim değişikliği ve fosil yakıtların sera etkisi üzerindeki rolü konusunda artan farkındalıkla birlikte, dünya daha temiz enerji kaynakları arayışına girmiştir; bu bağlamda, sıvılaştırılmış doğal gaz (liquefied natural gas-LNG) önemli bir alternatif olarak öne çıkmaktadır. Birçok ülke enerji sorunlarını çözmek ve dış ticaretin sürdürülebilir yollarını keşfetmek istemektedir. Azalan küresel petrol rezervleri ve yüksek petrol fiyatları, maliyet, taşıma kolaylığı ve sürdürülebilirlik gibi avantajları nedeniyle LNG'ye olan küresel talebi artırmaktadır .Bu çalışma, LNG dış ticaretinin bibliyometrik analizini yaparak konunun önemine dikkat çekmektedir. Bibliyometrik analiz, LNG ithalat ve ihracatına ilişkin akademik bakış açısını ana hatlarıyla ortaya koyarak, bu alanla ilgilenen araştırmacılar ve politika yapıcılar için değerli bir çerçeve sunmaktadır. Bu çalışmanın amacı, sektördeki genel eğilimleri belirlemek ve karar alma süreçlerini kolaylaştırmaktır. 31 Mayıs 2024'te, Web of Science (WoS) veri tabanında üç farklı anahtar kelime kullanılarak bir arama yapılmıştır: "Sıvılaştırılmış doğal gaz" (konu) ve "ithalat" veya "ihracat" (konu). Bu aramada, tarih kısıtlaması uygulanmayan toplam 273 yayın bulundu. Bu yayınların analizi, yazarlar, kaynaklar, ülkeler ve anahtar kelimeler dahil olmak üzere çeşitli kategorilerdeki eğilimleri incelemektedir. Bu bibliyometrik analiz, LNG ticaretinin dinamiklerine ilişkin anlayışımızı geliştirmekte ve bu araştırma alanının bilimsel bir haritasını oluşturarak gelecekteki araştırma yönlerini belirlemektedir. Yapılan analizler, LNG ithalat ve ihracatına ilişkin yayınların 1994-2024 yılları arasında artış göstermesinin de gösterdiği üzere, konuya olan ilginin ve önemin artarak devam ettiğini ortaya koymaktadır.

Energy has been an important part of the world agenda in recent years, both economically and politically. In the 21st century, with the growing awareness of climate change and the role of fossil fuels on the greenhouse effect, the world has been searching for cleaner energy sources; in this context, liquefied natural gas (LNG) stands out as an important alternative. Many countries want to solve their energy problems and explore sustainable ways of foreign trade. Declining global oil reserves and high oil prices increase the global demand for LNG with its advantages such as cost, ease of transport and sustainability. This study conducts a bibliometric analysis of the foreign trade of LNG, highlighting the significance of the subject. The bibliometric analysis outlines the academic perspective on LNG imports and exports, providing a valuable framework for researchers and policymakers interested in this area. The objective of this study is to identify general trends within the sector and to facilitate decision-making processes. On May 31, 2024, a search was performed in the Web of Science (WoS) database using three different keywords: “Liquefied natural gas” (topic) and either “import” or “export” (topic). This search yielded a total of 273 publications, with no date restrictions applied. The analysis of these publications examines trends across various categories, including authors, sources, countries, and keywords. This bibliometric analysis enhances our understanding of the dynamics of LNG trade and identifies future research directions by creating a scientific map of this research area. The analysis reveals that the significance and interest in the case continue to grow, as evidenced by an increase in publications on LNG imports and exports from 1994 to 2024.
