This article examines emerging dynamics in e-commerce supply chain research, with a particular focus on alliances and collaborations between key actors. It highlights the existing imbalances in the scientific literature and the lack of studies on large retailers such as Amazon. Through an innovative bibliometric analysis using Bibliometrix and VOSviewer software, we show data such as scientific output, sources and authors in recent years, as well as key insights for future research, including understanding collaboration between different actors in the supply chain. A total of 366 articles published between 2013 and 2023 were analysed, covering 917 authors, 222 journals, and 47 countries. The main finding of this research shows the growing interest in the supply chain of the e-commerce companies and the results provide clues for further investigation in this field.
