Innovation measurement remains a persistent challenge for organizations, especially in fast-evolving and complex sectors like ICT and IT, where traditional evaluation models struggle to capture the dynamic and intangible nature of innovation. Despite the abundance of proposed metrics and frameworks, the field remains fragmented, lacking a unified theoretical foundation and consistent methodological standards. This study addresses these gaps through a bibliometric analysis of 688 peer-reviewed articles published between 2001 and 2025, retrieved from Scopus and Web of Science. The analysis explores the evolution of scholarly production, identifies the intellectual roots of the field, such as the Resource-Based View, Dynamic Capabilities, and Absorptive Capacity, and maps the conceptual structure around key themes including open innovation, green and sustainable innovation, human capital, and knowledge management. The findings reveal a growing but dispersed research landscape, characterized by weak citation networks and parallel, often disconnected, research trajectories. Beyond describing the structural properties of the field, the study highlights the emergence of distinct thematic clusters aligned with different strategic and organizational perspectives. While this diversity reflects the complexity of innovation itself, it also underscores the need for more integrative and context-sensitive approaches to innovation measurement. By offering a comprehensive and data-driven overview of the literature, this study lays the groundwork for a forthcoming systematic literature review aimed at consolidating existing knowledge and supporting the development of robust, multidimensional frameworks. The results offer theoretical insights for advancing the field and practical implications for managers and policymakers seeking more effective tools to evaluate and guide innovation efforts.
