This study employs a dual-method approach, combining Data Envelopment Analysis (DEA) and truncated regression, to assess organizational sustainability performance and explore the influence of social responsibility practices. DEA evaluates relative efficiency among decision-making units, while truncated regression examines the relationship between social responsibility initiatives and sustainability outcomes. By integrating these methods, the research aims to unravel the complex interplay between social responsibility and sustainability, offering insights into how organizational behaviors impact overall performance. The findings have implications for strategic decision-making and policy formulation to foster sustainable practices across industries and regions. This study contributes to the understanding of sustainability management by providing empirical evidence on the effectiveness of social responsibility initiatives in driving sustainability outcomes.
