This study consolidates research on operational sustainability in dry ports. A total of 232 papers published in the last 23 years (2000–2023) are reviewed to assess the breadth of research perspectives in dry port sustainable operations. Additionally, the findings summarize current research trends, identify flaws in the body of knowledge, and suggest potential research areas. A bibliographic analysis approach is deployed to explore the existing body of knowledge, review the concepts in depth, and narrow the focus on potential research areas. Within this context, a content analysis technique has been utilized to explore and understand the conceptual underpinnings of specific themes, typically involving trending subjects like sustainability, dry ports, inland ports, economic sustainability, social sustainability, and environmental sustainability. Tools such as BibExcel and VOSviewer were utilized to assist in conducting the bibliometric analysis. The majority of dry port research has concentrated on the definition, functions, policy and governance, location analysis, ownership, and dry port-seaport interaction. Less attention is paid to dry port sustainability in line with the Sustainable Development Goals (SDGs), the interaction of internal and external collaboration with dry port sustainability, dry port social sustainability, dry port economic sustainability, dry port environment sustainability, and dry port service quality. Specifically, there has been limited research output on the sustainability of dry ports within the context of landlocked nations. This study will raise awareness of unexplored areas for further research by focusing on critical issues that are not generally covered by scholars in existing literature, such as dry port internal sustainability management and external collaboration.
