A Bibliometric Analysis and Disruptive Innovation Evaluation for the Field of Energy Security

The field of energy security is an important, complex and evolving field with important implications at the international, national and regional levels. Considering that no scholars have conducted bibliometric studies on the current energy security field, the authors of this study chose to use a bibliometric approach to conduct a search on the Web of Science using "energy security" as the keyword, and they conducted a systematic review of 5236 papers published between 2005 and 2022 to determine the current status and development of research in the field of energy security by addressing the following six questions: (1) What are the characteristics of the types of literature in the field of energy security? (2) What are the annual publication and citation frequency trends in the field of energy security? (3) What is the distribution of source journals, countries/regions, institutions, scholars and topics in the field of energy security? (4) What are the research hotspots in the field of energy security in the recent development history? (5) What are the most influential studies and the most disruptive studies in the field of energy security? (6) What are the characteristics of the different levels of cooperation networks in the field of energy security? Finally, we concluded the following: (1) In terms of publication dynamics, the number of annual publications and the citation frequency in the field of energy security maintain an upward trend, with a large number of source journals and a wide range of topics. The number of countries, institutions and scholars involved in research in the field of energy security keeps increasing, but the cooperation is fragmented and geopolitical. (2) From the perspective of research themes, research in the field of energy security has both strong technical characteristics and is associated with social science research themes. The contradictions between energy security and social, economic, environmental, land and climate issues, the interplay between energy supply systems and complex geopolitical and international relations issues and the important role of renewable energy and related technologies in maintaining national/regional energy security are the main issues of concern to researchers. (3) In terms of research centers, although the UK and the US still retain a first-mover advantage in this field, China has gradually overtaken and has become the country with the largest output of literature in recent years. The center of research in the field has also gradually shifted from Europe and the US to the East and South Asia regions. Overall, the governance of energy security issues still requires a combination of policy, economic and technological aspects. The results will help scholars systematically understand the current status of research, research frontiers and future trends in the field of energy security.
