There have been more studies on the circular economy (CE) and the internet of things (IoT) in recent years, but limited studies have examined how IoT can aid the CE. This study will use bibliometric tools to examine the current literature on IoT-CE and contribute to the expansion of knowledge in this field. The R package Bibliometrics was used to look at a set of more than 2,000 scientific papers from the Web of Science database about how IoT-based solutions can help improve the circular economy. This analysis helps us figure out how many papers are published each year by country, author, journal, and institution. With the number of publications around the world going up, the United States was the country with the most publications and citations, followed by the United Kingdom. Also shown in the results is how well journals, authors, and institutions did. The keyword analysis shows that research in these fields is getting more and more popular. The content analysis shows that IoT is mostly used in six areas: internet traceability and e-commerce, IoT adoption barriers in the supply chain, digitization in the supply chain, the effects of big data on the economy, the role of information technology in the circular economy, and supply chain performance. Therefore, these results can aid future research in this field by providing a global perspective of scientific research on IoT-based innovative solutions along-with the role of various digital technologies in achieving circular economy characteristics or dimensions.

近年来，关于循环经济（CE）和物联网（IoT）的研究越来越多，但关于物联网如何帮助循环经济的研究却很有限。本研究将使用文献计量工具来检查有关 IoT-CE 的当前文献，并有助于扩展该领域的知识。R 包 Bibliometrics 用于查看 Web of Science 数据库中的 2,000 多篇科学论文，内容涉及基于物联网的解决方案如何帮助改善循环经济。此分析帮助我们了解每年按国家、作者、期刊和机构发布的论文数量。随着世界各地出版物数量的增加，美国是出版物和引用次数最多的国家，其次是英国。结果还显示了期刊、作者和机构的表现。关键词分析表明，这些领域的研究越来越受欢迎。内容分析显示，物联网主要应用于六个领域：互联网追溯和电子商务、供应链中的物联网采用障碍、供应链数字化、大数据对经济的影响、信息技术在经济中的作用。循环经济和供应链绩效。因此，这些结果可以通过提供基于物联网的创新解决方案的科学研究的全球视角以及各种数字技术在实现循环经济特征或维度中的作用来帮助该领域的未来研究。
