电子商务示范城市对企业供应链效率的影响

The Impact of E-Commerce Demonstration Cities on Enterprise Supply Chain Efficiency

摘要: 当前，百年未有之大变局加速演进，数字化浪潮与全球化重构交织叠加，市场环境不确定性显著攀升。在此背景下，供应链效率作为企业抵御波动风险的核心能力、产业突破转型瓶颈的关键支点，其优化提升对经济高质量发展具有重要赋能价值。本文以2010~2023年中国A股上市公司为研究样本，系统考察电子商务示范城市建设与企业供应链效率间的因果关联。研究发现，电子商务示范城市建设能够显著提高企业供应链效率，在经过一系列稳健性检验后依旧成立。机制分析表明，企业数字化转型的深化与融资约束的缓解构成了上述影响的两大核心传导路径。异质性分析进一步揭示，该促进效应在非国有产权企业以及位于东部与中部地区的企业中表现得更为显著。本文研究贡献在于为政策制定者优化电子商务示范城市建设政策，企业发挥政策效能以提高供应链效率，提供了明确的作用机理阐释、传导路径揭示及差异化干预靶点。

Abstract: Currently, the unprecedented major changes are accelerating, with the interweaving and overlapping of the digital wave and globalization reconstruction, and the uncertainty of the market environment is significantly increasing. In this context, supply chain efficiency serves as the core capability for enterprises to resist volatility risks and the key pivot for industries to break through transformation bottlenecks. Its optimization and improvement have important empowering value for high-quality economic development. This article takes Chinese A-share listed companies from 2010 to 2023 as research samples to systematically examine the causal relationship between the construction of e-commerce demonstration cities and the efficiency of enterprise supply chains. Research has found that the construction of e-commerce demonstration cities can significantly improve the efficiency of enterprise supply chains, and it still holds true after a series of robustness tests. Mechanism analysis shows that the deepening of enterprise digital transformation and the alleviation of financing constraints constitute the two core transmission paths of the above-mentioned impacts. Heterogeneity analysis further reveals that this promotion effect is more significant in non-state-owned enterprises and enterprises located in the eastern and central regions. The contribution of this study is to optimize the construction policies of e-commerce demonstration cities for policy makers, and to enable enterprises to leverage policy effectiveness to improve supply chain efficiency. It provides a clear explanation of the mechanism of action, reveals the transmission path, and identifies differentiated intervention targets.
