基于LDA模型的跨境电商研究主题挖掘

Research Topic Mining of Cross-Border E-Commerce Based on LDA Model

摘要: 在全球化与数字技术快速发展的背景下，我国跨境电商已成为推动外贸增长的重要引擎。本文以2000~2024年CNKI数据库的1516篇中文核心期刊文献为研究对象，采用LDA主题模型的文本挖掘方法，系统分析跨境电商研究的主题分布情况。研究发现：(1) 跨境电商研究历程分为萌芽期(2001~2013年)、爆发期(2014~2020年)和成熟期(2021年后)三个阶段，研究热点与政策发布时间高度相关；(2) 关键词分析显示，“物流”“企业”“政策”“数字化”等核心研究维度，物流与供应链管理是跨境电商运营的核心环节；(3) LDA主题聚类识别出五大研究主题，包括跨境贸易政策与供应链协同创新、制造业进出口绩效评估与数字化转型、国际贸易商品与专业化人才培养、价值链协同与质量安全治理、数字丝路建设与跨境服务争议，揭示了跨境电子商务发展的演进路径。本研究为跨境电商研究领域提供了系统的文献分析框架，对政策制定与企业实践具有参考价值。

Abstract: Against the backdrop of rapid globalization and digital technology development, cross-border e-commerce in our country has become an important engine for promoting foreign trade growth. This article analyzes 1516 core Chinese journal articles from the CNKI database covering the years 2000 to 2024, utilizing the LDA topic model for text mining to systematically examine the topic distribution in cross-border e-commerce research. The study finds: (1) The research process of cross-border e-commerce can be divided into three stages: the budding period (2001~2013), the explosive period (2014~2020), and the mature period (after 2021), with research hotspots being highly related to the timing of policy releases; (2) Keyword analysis reveals that core research dimensions such as “logistics”, “enterprises”, “policies”, and “digitalization” are pivotal, indicating that logistics and supply chain management are central to the operation of cross-border e-commerce; (3) The LDA topic clustering identifies five major research themes, including cross-border trade policies and supply chain collaborative innovation, assessment of import and export performance in manufacturing and digital transformation, international trade goods and specialized talent cultivation, value chain collaboration and quality safety governance, and the construction of a digital Silk Road with controversies in cross-border services, exposing the evolutionary path of cross-border e-commerce development. This study offers a systematic literature analysis framework for the field of cross-border e-commerce research and holds significant reference value for policy formulation and corporate practices.
