# Development and Future Trends of Digital Product-Service Systems: A Bibliometric Analysis Approach
## 5 Conclusions  
In this study, we performed a bibliometric analysis of the digital PSS field using cooperation, content, sources, keywords, and trend analysis. By providing a thorough overview of the existing literature and tackling three research gaps related to the key authors, significant subject areas, and future research objectives in the field, this study seeks to address the dearth of digital PSS research. The findings from the research question _\"Which prestigious authors, countries and sources have made the biggest contributions to the digital PSS literature?\"_ compile the most important bibliometric information from the Scopus database in the field of digital PSS. As a result, the answer to the research question _\"Which significant subject areas come to light in the digital PSS literature?\"_ offers a short content analysis and key terms that highlight the main topics in the field of digital PSS. The most important topics in the field, according to the content analysis of the most cited papers, are Digital Disruption and Value Capture, the Analysis of Ecosystems in Digital Servitization, Smart PSS and Service Innovation, Organizational Change and Digital Servitization, Financial Performance and the Interplay between Digitalization and Servitization, and the Internet of Things' Impact on Service-Oriented Business Models. Finally, the response to the research question _\"What are the future research trends of digital PSS?\"_ reveals a more in-depth conceptual paradigm for the convergence of digital PSS and Industry 5.0. These findings are confirmed by the paper's major contribution, which is a content and keyword co-occurrence analysis that reveals expanding trends in the field of digital PSS. As a result, this study is a significant addition to the body of literature because it combined earlier studies and offered a cutting-edge conceptual framework for furthering research into digital PSS. This study offers helpful information about the major contributors and major publishers of research in the field of digital PSS based on the theoretical consequences. In addition, this study theoretically demonstrates the key topics in the field of digital PSS, including digital servitization, service business models, digital technologies and advances, the design of smart PSS, and industrial transformation processes. Additionally, this research provides a forecast of the growth of digital PSS in Industry 5.0. A conceptual framework that depicts future service development based on human-centric, sustainability,

Based on these practical implications, this study demonstrates the digital PSS change processes and the dominant issue in this area. Additionally, this study reveals the most widely referenced papers that highlight the significance of ecosystems, technology, and organization in the evolution of digital PSS. The results of this research also demonstrate how Industry 5.0's new manufacturing approach could incorporate digital PSS. This study's primary practical consequence is that understanding how important services are to manufacturing firms is what drives them to utilize the right digital PSS in order to perform better and resolve the \"serviization paradox\" issue. However, it is important to keep in mind that there are still some limitations to this research. Refreshing the data provided by bibliometric research over time is necessary. Additionally, only the Scopus database was used to obtain the data for this study. This study's findings could only provide a summary of the relevant areas and some recommendations for the future. According to this study's limitations, the authors recommend that future research incorporates information from additional pertinent databases, such as Web of Science.
