Abstract:
The integration of digital technologies into human resource management, known as HRM 4.0, represents a paradigm shift in how organizations manage their workforce. Despite the proliferation of research on artificial intelligence (AI), big data, and automation in HR, the academic literature remains fragmented, often focusing on isolated technological applications rather than providing a comprehensive overview of the field's evolution. This study addresses this gap by conducting a bibliometric analysis to map the intellectual structure, current trends, and future directions of HRM 4.0 research. Employing a systematic review methodology, this study analyzed 2,743 peer-reviewed articles published between 2020 and 2025, sourced from the Scopus database. Performance analysis and science mapping techniques were utilized to identify the most influential authors, countries, and journals, as well as to visualize the thematic clusters within the field. The findings reveal a robust annual growth rate of 22.3% in publications, with key research themes converging around AI-driven recruitment, algorithmic performance management, digital talent management, and employee surveillance. The analysis further uncovers critical gaps in the literature, particularly concerning the ethical implications of AI, cross-cultural validation of digital HR practices, and sector-specific adoption challenges. The study concludes that while HRM 4.0 offers significant opportunities for efficiency and personalization, it also introduces profound ethical and social dilemmas that demand urgent scholarly attention. This paper provides a clear roadmap for future research and offers practical insights for HR professionals navigating this digital transformation.
