基于科学知识图谱的冷链物流成本优化研究热点分析

In recent years, China\'s cold chain logistics industry has experienced rapid development, attracting significant academic attention. This paper focuses on the research theme of cold chain logistics cost optimization. By constructing a scientific knowledge map, the paper explores the research progress and trends in this field. A total of 386 Chinese and English articles on "cold chain cost optimization" published between 2006 and 2023 were collected from the China National Knowledge Infrastructure (CNKI) and Web of Science core collections. Using CiteSpace software for knowledge map analysis, the study found a continuous increase in the annual number of publications and identified highly contributing research institutions and authors. Through keyword clustering and burst analysis, research hotspots were highlighted, revealing that cold chain logistics will evolve towards green and intelligent systems, driven by customer demand.
