电商企业供应链效率优化：数字化转型的价值

Optimizing E-Commerce Enterprise Supply Chain Efficiency: The Value of Digital Transformation

摘要: 在数字经济成为我国经济高质量发展核心引擎、电商行业竞争聚焦供应链效率的背景下，本文以2013~2023年同花顺电子商务概念板块上市公司为样本，实证探究电商企业数字化转型对供应链效率的影响及作用机制，并分析异质性特征。研究表明，数字化转型有效缩短库存周转天数；企业ESG表现在二者关系中起中介作用，数字化技术降低ESG信息披露成本、提升评级，高评级向供应链传递 “可信信号”。异质性分析显示，该提升作用在非高新技术企业、非制造业企业及东部地区企业中更突出。基于此，本文建议政府出台差异化政策破解发展不均衡，企业结合自身特征推进数字化并借ESG强化供应链协同，第三方机构优化电商行业ESG评级体系，助力提升企业供应链效率，实现数字经济高质量发展。

Abstract: Against the backdrop of the digital economy becoming the core engine of China’s high-quality economic development and competition in the e-commerce industry focusing on supply chain efficiency, this paper takes listed companies in the Tonghuashun e-commerce concept sector from 2013 to 2023 as samples to empirically examine the impact and mechanisms of action of digital transformation of e-commerce enterprises on supply chain efficiency, and analyze the heterogeneity characteristics. The results show that digital transformation effectively shortens inventory turnover days; corporate ESG performance plays an intermediary role in the relationship between the two—digital technology reduces ESG information disclosure costs and improves ratings, and high ratings send “credible signals” to the supply chain. Heterogeneity analysis indicates that this enhancement effect is more pronounced in non-high-tech enterprises, non-manufacturing enterprises, and enterprises in the eastern region. Based on this, this paper suggests that the government formulate differentiated policies to address the imbalance in development, enterprises advance digitalization in light of their own characteristics and leverage ESG to strengthen supply chain collaboration, and third-party institutions optimize the ESG rating system in the e-commerce industry to help improve enterprises’ supply chain efficiency and promote the high-quality development of the digital economy.
