Green logistics (GL) is the main development trend of modern logistics. The analysis of green logistics topics and their evolution is helpful in grasping its development trend and doing research facing the international frontier. Focusing on the hot topics and evolution process of green logistics, this paper analyzes from four aspects: firstly, this study divides the green logistics development progress into three stages based on life cycle theory, which are the emerging stage (1993-2003), slow growth stage (2004-2014) and rapid growth stage (2015-2021). Then, based on latent dirichlet allocation (LDA) topic model, this study summarizes and confirms related words and meaning of each topic in different stages. Furthermore, this study calculates the text similarity in each development stage of green logistics and analyzes the trend of hot topics in green logistics. Finally, this paper visualizes the development roadmap of green logistics and explores the progression among three stages. There are 4, 5, and 7 topics defined respectively in three development stages. The revolution of green logistics is analyzed, and the results show that "model and management on sustainable development of GL", "related issues and potential threats of GL", and "optimization analysis of low-carbon vehicle routing and time" are the primary development trends of green logistics. This study fills the gap in considering the evolution process of green logistics through topic modeling and roadmapping method. It provides a particular theoretical significance for the green and sustainable development of logistics.
绿色物流（GL）是现代物流的主要发展趋势。分析绿色物流主题及其演变有助于把握其发展趋势，面向国际前沿开展研究。本文聚焦于绿色物流的热点主题和演变过程，从四个方面进行分析：首先，基于生命周期理论，本文将绿色物流发展进程划分为三个阶段，即新兴阶段（1993-2003 年）、缓慢增长阶段（2004-2014 年）和快速增长阶段（2015-2021 年）。然后，基于潜在狄利克雷分配（LDA）主题模型，总结和确认了不同阶段每个主题的相关词汇和含义。此外，计算了绿色物流不同发展阶段的文本相似度，分析了绿色物流的热点主题趋势。最后，可视化绿色物流的发展路线图，探讨三个阶段之间的演进。在三个发展阶段中分别定义了 4、5 和 7 个主题。分析了绿色物流的变革，结果表明，“GL 可持续发展的模型与管理”、“GL 的相关问题和潜在威胁”以及“低碳车辆路径和时间的优化分析”是绿色物流的主要发展趋势。本研究通过主题建模和路线图方法考虑绿色物流的演变过程，填补了这一空白。它为物流的绿色和可持续发展提供了特定的理论意义。
