This study investigates the impacts of environmental accounting, green supply chain management (GSCM), and import regulations on firm performance. Using a quantitative research design, this study employs Partial Least Squares Structural Equation Modeling (PLS-SEM) to examine 192 managers from the health equipment industry. The research employs a comprehensive array of measurement items derived from interdisciplinary literature to assess the intricate relationships among the primary variables in a multifaceted manner. This research underscores the favorable effect of environmental accounting on bolstering green supply chain management (GSCM) practices and dexterously navigating import regulations, which ultimately prove to be highly beneficial for a firm's performance. This study validates the potency of a circular economy approach, with resource efficiency emerging as a crucial aspect in maximizing both ecological and financial outcomes. The measurement model developed in this study is a dependable resource for future research and practical applications aimed at promoting sustainability in the industry.
