The purpose of this study is to outline the current state of research and development in Industry 4.0 by highlighting key topics, cooperative networks, and emerging trends that characterize this ground-breaking stage of manufacturing and technology. The article answers the question what are the key keywords, countries, collaboration networks and most frequently occurring terms in Industry 4.0 research, and what conclusions can be drawn from the bibliometric analysis regarding their frequency, strength of connections and mutual relationships. With a focus on the incorporation of digital technology into manufacturing processes, the article aims to provide a detailed overview of the international initiatives driving the fourth industrial revolution. This study uses bibliometric analysis to look at 4,981 scientific papers from 2020 to 2024 that are available in the Scopus database. The text of these articles is carefully examined, with an emphasis on titles, abstracts, and keywords, in order to map out the network of co-authorships and the frequency of certain terminologies. The VOSviewer program was used to provide a network visualization, offering a pictorial depiction of the connections of coauthoring nations and the phrases that are shared across the corpus of work. The results show a strong and complex web of global partnerships, suggesting a broad dedication to pushing the boundaries of Industry 4.0. Five significant co-authorship clusters were found, demonstrating the prominent significance that certain nations have played in various Industry 4.0 research domains. Key phrases like “digital transformation,” “smart manufacturing,” “machine learning,” and “internet of things” were used a lot, highlighting the importance of digitization and smart manufacturing technology. This publication offers a comprehensive statistical and visual study of the worldwide research dynamics in Industry 4.0, making it a unique contribution to the body of knowledge. Understanding the complex nature of the fourth industrial revolution is made easier with its mapping of cooperative networks and thematic goals as well as its emphasis on the discourse’s essential place for sustainability.
