基于2010~2022年沪深A股上市公司及其供应链关系数据，探讨环境监管压力对供应链企业绿色转型的影响及其内在机制。研究发现，核心企业的环境监管压力有效促进了供应商企业的绿色转型。机制分析表明，核心企业环境监管压力主要通过风险管理协同、信息透明协同和技术创新协同，推动供应商企业绿色转型。异质性检验发现，当核心企业的市场集中度和供应链话语权越大时，核心企业环境监管压力对供应商绿色转型的促进作用就越显著；此外，供应商的融资约束和环境污染水平也表现出明显的异质性特征。进一步分析发现，核心企业环境监管压力在供应链上下游企业间的传导具有非对称性，且当核心企业具有绿色领先地位时，其环境监管压力的传导效果更加显著。

Using data from Chinese A-share listed companies and their supply chain relationships from 2010 to 2022, this study examines the impact of environmental regulatory pressure faced by focal firms on the green transformation of their suppliers and explores the underlying mechanisms. The findings indicate that environmental regulatory pressure on focal firms significantly fosters the green transformation of suppliers. Mechanism analysis reveals that the environmental regulatory pressure on focal firms primarily drives the green transformation of suppliers through coordination in risk management, information transparency, and technological innovation. Heterogeneity analysis indicates that the greater the market concentration and supply chain influence of focal firms, the more significant the impact of environmental regulatory pressure on the green transformation of suppliers. Moreover, the financing constraints and environmental pollution levels of suppliers also exhibit notable heterogeneous characteristics. Further analysis reveals that the transmission of environmental regulatory pressure on focal firms between upstream and downstream firms in the supply chain is asymmetric, and that the transmission effect becomes more pronounced when focal firms hold a leading position in green development.
