基于手工搜集的试点碳市场控排企业名录，实证检验碳排放权交易机制通过在供应链“自下而上”的传导对绿色转型的影响。研究发现：当客户受到碳排放权交易机制的约束与激励时，能够推动供应商绿色转型且长期有效。而且，压力传导效应和利益驱动效应是供应商绿色转型的动力；供应商绿色转型的路径是摆脱“表面的、末端的”转型，实现“实质的、清洁生产的”转型。进一步研究发现：当供应商所在地政府环境治理力度较高、供应商成本转嫁能力较低时，客户被纳入碳排放权交易试点对供应商绿色转型的促进作用更显著；供应商人工智能技术的应用能够为其绿色转型提供支撑。此外，客户被纳入碳排放权交易试点推动供应商绿色转型后，能够产生供应链绿色合作共赢效应且长期更有效。

Based on a manually compiled directory of regulated firms in pilot carbon markets, this study empirically examines the impact of the carbon emission trading scheme on green transformation through its “bottom-up” transmission along the supply chain. The findings reveal that when customers are subject to the constraints and incentives of the carbon emission trading scheme, they can drive their suppliers’ green transformation, with persistent effects observed in the long term. Moreover, pressure transmission effects and benefit-driven effects are identified as key drivers of suppliers’ green transformation. The pathway for suppliers involves moving away from “superficial and end-of-pipe” transformations toward achieving “substantive and cleaner production” transformations. Further analysis shows that the promoting effect of customers’ inclusion in carbon emission trading pilots on suppliers’ green transformation is more pronounced when suppliers operate in regions with stronger government environmental governance or possess lower cost-pass-through capabilities. Additionally, the application of artificial intelligence technology by suppliers can provide essential support for their green transformation. Finally, when customers are included in carbon emission trading pilots and drive their suppliers’ green transformation, a win-win effect of green supply chain collaboration is generated, which becomes more effective over the long term.
