The prosperity of cross-border e-commerce (CBEC) has boosted the global economy and strengthened international trade ties. It arouses wide attentions among scholars, which leads to the appearance of massive researches in the CBEC field, which makes it difficult to do a comprehensive and objective analysis in CBEC field by traditional literature review methods. Two bibliometric methods, main path analysis (MPA) and science mapping technology (SciMAT), are used in this study to explore the significant knowledge development trajectory and identify the academic theme evolution in the CBEC field. The CBEC field has three academic origins, namely strategic research, culture adaptability, and online marketing. The theme evolution analysis identifies the key academic themes in different periods; we divide the CBEC field into five different research clusters according to the evolution relations. This study comprehensively analyzes the development process and structures the knowledge construction for the CBEC field, which is advantageous to deepen the understanding of CBEC and provide the enlightenment for future researches.

跨境电商的繁荣提振了全球经济，加强了国际贸易联系。它引起了学者们的广泛关注，导致跨境电商领域出现了大量的研究，这使得传统的文献综述方法难以对跨境电商领域进行全面、客观的分析。本研究采用主路径分析（MPA）和科学图谱技术（SciMAT）两种文献计量方法来探索CBEC领域的重要知识发展轨迹并识别学术主题演变。跨境电商领域具有三个学术渊源，即战略研究、文化适应性和网络营销。主题演变分析，识别不同时期的关键学术主题；我们根据演化关系将CBEC领域分为五个不同的研究集群。本研究全面分析了跨境电商领域的发展历程，构建了跨境电商领域的知识建构，有利于加深对跨境电商的认识，为今后的研究提供启示。
