Servitization and product service system: A literature review on value creation

In recent years, the concept of servitization has been widely applied in the management of enterprises. However, changing customer demands and competitive pressures of the market have compelled enterprises to seek innovation. Simultaneously, in the context of the Industry 4.0 trend, the rapid development of digital technologies has led to an increasing number of studies on the integration of servitization and digitization. Therefore, this study, based on VOSviewer, Gephi, Scimago Graphica, and Histcite, analyzes the current state and development trends of research on servitization and product service system innovation from the perspective of value creation. Initially, basic statistical characteristics such as the influential author, geographical cooperation, and highly cited papers are presented by collecting relevant data from the Web of Science core collection database. Subsequently, this study explores the research hotspots and evolutionary trends in servitization and product service system innovation through keyword co-occurrence analysis and cluster analysis. Lastly, from a literature analysis perspective, the application of advanced technologies in servitization, digital servitization from an ecosystem perspective, and the innovative use of microservices architecture in product service systems are summarized and forecasted as research directions, providing theoretical guidance for future research in servitization.
