Mapping the intellectual structure of digital transformation research in SMEs: A decade of performance-oriented studies

Abstract

Despite their vital contribution to worldwide economic progress, small and medium-sized enterprises (SMEs) are vulnerable to environmental fluctuations, resource limitations, and swift technological shifts. In this context, digital transformation has emerged as a critical strategic mechanism through which firms seek to enhance competitiveness, resilience, and organizational outcomes. Although this topic has attracted considerable scholarly attention in recent years, the available literature is dispersed across different academic fields, theoretical viewpoints, and methodologies, making it difficult to gain a holistic understanding of the area’s intellectual organization and progression. To address this gap, this study conducts a systematic bibliometric analysis to examine digital transformation and firm-level outcomes in small business contexts from January 2016 to January 2026. Bibliographic data were retrieved from the Scopus database and analyzed using Bibliometrix through its Biblioshiny interface and VOSviewer. A final dataset of 186 peer-reviewed journal articles was examined using descriptive statistics, keyword co-occurrence analysis, bibliographic coupling, citation analysis, thematic mapping, and research trend analysis. The results indicate a strong and accelerating publication trend, with an annual growth rate of 17.46%, particularly since 2020, highlighting the increasing strategic importance of digital technologies in response to economic disruptions and uncertainty. The analysis identifies four major thematic clusters: (1) performance-oriented outcomes, (2) technology - and capability-driven transformation, (3) organizational and sustainability-related performance, and (4) strategic and Industry 4.0-oriented transformation. In addition, emerging themes include digital readiness, dynamic capabilities, and business model innovation. While the literature frequently associates digital transformation with improved organizational outcomes, the findings also reveal persistent heterogeneity in results and highlight substantial risks and failure rates, especially among resource-constrained firms. By mapping the intellectual foundations, thematic structure, and evolution of this research domain, the study provides an integrative overview that supports theory development and informs future empirical research. The results also offer valuable insights for scholars, practitioners, and policymakers who seek to understand and guide digital transformation initiatives in small business contexts.
