中文摘要:

      可持续发展浪潮下,低碳减排成为企业实现高质量发展的必由之路。利用2010—2021年中国A股上市公司数据,基于ESG信息强制披露视角,实证检验了境外绿色客户对供应商碳绩效的影响及作用机制。研究发现,境外绿色客户能够促进供应商碳绩效提升,且通过供应商绿色研发创新能力的提高促进其碳绩效的提升。此外,企业间的地理距离削弱了这种提升效应,而供应商市场竞争程度则强化了该提升效应。异质性分析发现,境外绿色客户对供应商碳绩效的提升效应在国有企业、成熟期企业、境外客户集中度高的企业及通过绿色体系认证的企业中更为显著。进一步地,境外绿色客户能够增强供应商碳绩效对其企业价值的提升作用。因此,政府应建立跨境供应链碳信息共享平台,积极与国际绿色标准接轨；企业应注重绿色人才的培养,加强绿色供应链建设,共同推动中国经济高质量发展。

英文摘要:

      Against the backdrop of sustainable development, low carbon and emission reduction have become essential paths for enterprises to achieve high-quality growth. Using data from China's A-share listed firms from 2010 to 2021, and from the perspective of mandatory environmental, social, and governance (ESG) information disclosure, this study empirically examines the impact of overseas green customers on suppliers' carbon performance and the underlying mechanisms. The results show that overseas green customers improve suppliers' carbon performance, primarily by enhancing suppliers' green research, development, and innovation capabilities. Further analysis indicates that geographic distance between firms weakens this positive impact, whereas a higher degree of market competition among suppliers strengthens it. Heterogeneity analysis reveals that the positive impact is more pronounced among state-owned enterprises, firms in the mature stage of development, those with a high concentration of overseas customers, and those that have obtained green system certification. Additional evidence suggests that overseas green customers amplify the positive effect of suppliers' carbon performance on firm value. Accordingly, the government should establish cross-border supply chain carbon information-sharing platforms and actively align domestic standards with international green standards. Enterprises should focus on cultivating green talent and strengthening green supply chain development, thereby jointly promoting the high-quality development of China's economy.
