数字金融缓解中小企业融资约束的机制与路径分析

Analysis of the Mechanism and Path of Digital Finance in Alleviating the Financing Constraints of Small and Medium-Sized Enterprises

摘要: 实体经济的毛细血管能否畅通，很大程度上取决于千万家中小企业能否获得充足的资金活水。受制于传统金融体系的结构性局限，中小企业长期陷于“差钱”的泥沼。本文脱离传统经验实证的统计学框架，从微观经济学、信息经济学与契约理论的底层逻辑出发，重新审视数字金融这一新血液如何重塑金融市场的资源配置法则。研究发现，数字金融绝非传统银行业务在互联网上的简单平移，而是通过数据要素的深度介入，将企业日常的“数字足迹”转化为可变现的信用资产，从根本上消解了传统信贷市场中因信息不透明引发的信贷配给与抵押品崇拜。在具体的破局路径上，数字金融不仅降低了企业的综合债务融资成本，还产生强大的信号传递效应，协同激活了供应链上的商业信用。更有价值的是，数字技术的嵌入打通了供应链金融的信任断层，并倒逼企业进行数字化转型，最终为孕育“新质生产力”提供了充沛的资本底座。任何金融创新都无法脱离现实的土壤，企业的财务信息透明度、产权背景差异以及地方制度环境的完善程度，构成了数字金融发挥效能的隐形边界。本文力求在理论的严谨性与现实的生动性之间寻找平衡，为理解数字时代金融如何真正赋能实体经济提供一种新颖的思辨框架。

Abstract: The smooth flow of the “capillaries” of the real economy depends largely on whether millions of small and medium-sized enterprises (SMEs) can obtain sufficient capital. Constrained by the structural limitations of the traditional financial system, SMEs have long been trapped in financing difficulties. Departing from the traditional statistical framework of empirical analysis, this paper re-examines how digital finance reshapes the rules of resource allocation in financial markets from the underlying logics of microeconomics, information economics and contract theory. The study finds that digital finance is by no means a simple online migration of traditional banking business. Instead, through the deep integration of data factors, it transforms enterprises’ daily “digital footprints” into realizable credit assets, fundamentally eliminating credit rationing and collateral dependence caused by information opacity in the traditional credit market. In terms of specific solutions, digital finance not only reduces enterprises’ overall debt financing costs but also generates a strong signaling effect, which synergistically activates commercial credit in the supply chain. More importantly, the integration of digital technology bridges the trust gap in supply chain finance and forces enterprises to carry out digital transformation, ultimately providing a solid capital foundation for nurturing “new quality productive forces”. No financial innovation can exist in isolation from reality. The transparency of enterprises’ financial information, differences in property rights backgrounds, and the improvement of local institutional environments constitute the invisible boundaries for digital finance to function effectively. This paper strives to strike a balance between theoretical rigor and practical relevance, providing a novel analytical framework for understanding how finance in the digital era can truly empower the real economy.
