The concept of digital platforms has attracted a great deal of attention in the fields of economics and information systems, shaping scholarly discourse for the past few years. However, despite the frequent usage of the term “digital platform” in the literature, its definition covers a wide range of meanings. Scholars often use the term to mean very distinct concepts which creates a sort of semantic confusion within the scientific community. To clarify the different elements and perspectives shaping the definition of a digital platform, a systematic literature review was carried out. A total of 64 definitions from 58 scholarly resources were collected and analyzed through qualitative content analysis. This analytical process aimed to isolate and identify the fundamental elements used in defining digital platforms, along with discerning the multiple perspectives from which this term is approached. Furthermore, this study traces the evolution of the definition of the concept in parallel with the dynamic development of digital platforms in recent years.
