Network analysis and the evolution of key concepts in container terminal research

Abstract

In the contemporary global economy, characterized by increasing supply chain complexity, container terminals (CTs) play an indispensable role in ensuring the efficiency of international trade. This study aims to conduct a network analysis to identify the evolution of key concepts within the field of CT research. The primary objective of the article is to identify dominant thematic clusters and current research directions using scientometric tools, particularly VOSviewer software and data from Scopus and Web of Science databases. Furthermore, an important task is to assess the applicability of the identified global trends for the development of the transport and logistics system of the Republic of Uzbekistan. The findings demonstrate the multidimensional nature of CT research, highlighting both established clusters (operational efficiency, infrastructure design, supply chain integration) and dynamically developing areas, primarily related to digitalization and sustainability. The analysis also enabled the identification of conceptual shifts and so-called "hot spots" within this scientific domain. The concluding section discusses the significance of these results for formulating scientifically-grounded approaches to the modernization and development of CTs and transport-logistics centers in Uzbekistan, aligning with national strategic priorities, and for determining promising vectors for future research.
