Outline
To explore the emerging research field of cross-border e-commerce, a bibliometric approach was adopted to conduct a comprehensive analysis of relevant literature on cross-border e-commerce in CNKI. The analysis covered the publication trends of cross-border e-commerce, the cooperation among major research institutions and core authors, as well as the current research hotspots and frontier shifts. The study finds that the research process of cross-border e-commerce can be divided into three stages such as initial sprouting, vigorous development and mature optimization. During this period, although some research institutions and authors have initially formed a cooperation network, the depth and breadth of cooperation still need to be improved. The research focus has gradually shifted from topics such as cross-border logistics and the Belt and Road Initiative to areas such as the digital economy, digital trade and expanded opening up. Future research on cross-border e-commerce should focus on areas such as the digital economy, digital trade and expanded opening up, and strengthen cross-university and cross-regional cooperation to enhance the innovation capacity of research.
