摘　　要：作为水环境治理的关键力量,政府、企业和社会公众的多主体参与对水环境治理效率的影响尤为重要。基于2012~2021年长江经济带11个省(市)的面板数据,采用超效率SBM-DEA模型测算水环境治理效率,构建水资源总量距离权重矩阵,并通过空间杜宾模型和面板门槛模型分析多主体参与对治理效率的影响。此外,还运用中介模型检验了政府绿色科技支持和企业绿色转型的作用。结果表明:①多元主体参与显著提升了水环境治理效率;②多元主体参与通过协同驱动作用提升了区域水环境治理成效,但在长江上游、中游、下游不同地区的治理成效呈差异性显著;③政府绿色科技支持和企业绿色转型通过中介效应有效改善了水环境治理效率;④主体间参与度变化对水环境治理效率具有门槛效应。研究成果可为长江经济带水环境治理提供理论依据和政策建议,有助于实现区域水环境的可持续发展。As critical actors in water environment governance,the multi-stakeholder participation of governments,enterprises,and the public exerts significant influence on governance efficiency.In this study,we analyze panel data from 11 provinces and municipalities in the Yangtze River Economic Belt(YREB)from 2012 to 2021.Methodologically,we measure water environment governance efficiency(WEGE)using a super-efficiency SBM-DEA model,construct a distance-weight matrix based on total water resources,and employ spatial econometric techniques(spatial Durbin model,SDM)combined with a panel threshold model to quantify the impact of multi-stakeholder participation on WEGE.Furthermore,a mediation model is employed to examine the roles of government green innovation incentives and corporate green transition.Key findings include:①Multi-stakeholder participation significantly enhances WEGE.②Collaborative interactions among stakeholders improve regional governance outcomes,although the effectiveness varies significantly across the upper,middle,and lower reaches of the Yangtze River.③Government green innovation incentives and corporate green transition effectively improve WEGE through mediation effects.④Threshold effects emerge when stakeholder engagement reaches critical levels.This research provides theoretical foundations and policy recommendations for optimizing multi-agent governance mechanisms in the Yangtze River Economic Belt,advancing sustainable development of regional water environments.
