Over the past decade, the body of literature on intellectual capital and knowledge management has grown exponentially, responding to the growing knowledge-based and digital economy. This article reviews the concepts and applications proposed at the initial stages of the launch of these two research paradigms. It then examines the interconnection between the two. The study selected a set of articles on intellectual capital and knowledge management that forward concepts and applications vital to the inception of these two research domains. The analytical review demonstrates that these concepts and applications, although considered separately in research, are interconnected and inform each other. The paper analyzes, discusses, and forms conclusions based on the self-selected literature with informed research knowledge.
