The growing pressure on businesses to align with sustainable practices has led to increased interest in how digital technologies, particularly Big Data Analytics (BDA) capabilities, can drive Corporate Sustainability (CS). However, the mechanisms through which BDA capabilities enhance sustainability, along with Business Model Innovation (BMI), are relatively underexplored in small and medium enterprises (SMEs) of emerging economies. The objective of this study is to bridge this gap by analyzing the influence of BDA capabilities on CS, with the mediating role of BMI in Bahraini SMEs. Data were collected from 210 SME managers and decision-makers using a purposive sampling technique. The hypotheses were tested using the Structural Equation Modeling (SEM) in AMOS. The results reveal that BDA capabilities have a significant effect on BMI and CS, and BMI partially mediates between BDA capabilities and CS. The research findings are invaluable for SME managers and policymakers to apply BDA capabilities to achieve BMI and sustainability goals.
