This study addresses the research gap in assessing multinational enterprises' (MNEs') efficiency across multiple dimensions by employing a novel chance‐constrained network data envelopment analysis. Unlike prior studies that focus on single‐dimensional efficiency, our approach evaluates operating, R&D, profitability, and sustainable efficiencies simultaneously. We find that MNEs in Asia (Europe) excel in operational and R&D efficiencies (profitability and sustainable efficiencies), while MNEs in Europe (Asia) lag behind. By integrating Michael Porter's generic strategies framework, we categorize efficiencies into four quadrants for strategic insights. Furthermore, we examine the nonlinear impact of ESG performance (ESG score and ESG combined score) on efficiency, revealing that multinationality negatively moderates the ESG–efficiency relationship. These findings provide novel insights into how ESG engagement and multinationality influence MNE performance, offering strategic guidance for firms navigating global complexities and sustainability challenges.
