ESG hushing is an ESG alienation phenomenon， characterized by the intentional avoidance or reduction of ESG commitments and actions， posing a serious threat to the achievement of sustainable development goals. Currently， there is a lack of attention to ESG hushing in academia， and most of the few existing researches focus on green hushing， failing to fully reveal the conceptual definition， driving mechanisms， impact effects， and governance strategies of ESG hushing. Starting from the conceptual definition of ESG hushing， it clarified that its essence is part of the corporate ESG strategy continuum， and its main manifestation is to avoid or reduce the commitment to ESG goals， actual actions and performance communication. Based on the logic of “driving factor-influence effect-governance strategy”， it systematically analyzed ESG hushing. By constructing an ISV model， the driving mechanism of ESG hushing is summarized into three core factors： institutional pressure， proactive strategy and managerial value perception. Further， the negative impacts of ESG hushing on the long-term sustainable development of enterprises， the development of ESG ecology and the sustainable development of society are explored. Finally， based on the complete process of corporate ESG behavior， a governance strategy of collaborative governance among the government， corporations， and third-party subjects is proposed， aiming to enhance the proactiveness of corporate ESG practices and the consistency of communication. The findings deepen the understanding of ESG hushing， improve related governance theories， and provide theoretical support and practical guidance for promoting global ESG development and realizing sustainable development goals.
