摘要
为实现经济绿色转型,达到“双碳”目标,国家级自愿型环境规制正日益成为关键性的政策工具。以国家级绿色工厂认证为准自然实验,基于“供应商-客户”二级供应链的研究视角,考察供应商获评绿色工厂对客户企业产出波动的非约束性影响及作用机制。研究结果表明,供应商获评绿色工厂显著抑制了客户企业产出波动,其中,供应链协调下的供应链双向稳定需求提升效应和供应链效率增强效应是重要影响渠道。供应商和客户的特征对缓解效果均存在异质性影响,当供应商属于非十大重点行业、所在省市存在政府采购类需求侧政策,客户属于非重污染行业、具有低融资约束水平时,效果更强。拓展性分析发现,采购比例具有上下阈值限制,只有适度依赖型采购战略才能实现稳定供给和弹性变动间的均衡。此外,供应链协调效应会产生垂直和水平溢出,上游企业绿色认证可以降低中游企业供需波动偏离度并弱化长鞭效应的传导,共享大客户会产生对链外非绿色供应商的非约束性影响。研究表明,绿色工厂建设会对未被规制企业产生协同效应,这为政策效果评估及缓解供需失衡问题提供了重要启示。
National-level voluntary environmental regulations have increasingly become key policy instruments for achieving green economic transformation and meeting the“dual carbon”goals.Taking the national green factory certification as a quasi-natural experiment,this paper examines the non-mandatory impact of suppliers certification as green factories on their customers output fluctuation from the perspective of a two-tier supplier-customer supply chain,as well as the underlying mechanisms for this effect.The results show that suppliers being certified as green factories significantly reduce the output fluctuation of their customer firms.The demand-enhancement effect of bidirectional supply chain stability and the efficiency improvement obtained through supply chain coordination constitute the main transmission channels.The heterogeneity analysis reveals that the mitigating effect is stronger when suppliers operate in non-key industries or in provinces with demand-side policies,such as green government procurement,and when customers belong to non-heavily polluting industries or face lower financing constraints.Further analysis shows that the proportion of procurement exhibits both upper and lower threshold effects:a moderately dependent procurement strategy achieves a balance between stable supply and flexible adjustment.Moreover,the coordination effect generates vertical and horizontal spillovers—upstream firms green certification reduces midstream firms supply-demand fluctuation and weakens the propagation of the bullwhip effect;shared major customers impose non-mandatory influences on non-certified suppliers outside the chain.The findings indicate that the construction of green factories produces synergistic benefits for unregulated firms,offering important insights for policy evaluation and for alleviating supply-demand imbalances.
