摘 要
企业融资渠道选择与资本成本控制是现代企业财务管理中的核心议题，尤其在全球经济不确定性增加和金融市场结构不断变化的背景下，研究这一问题具有重要的理论价值和实践意义。本研究旨在探讨不同融资渠道对企业资本成本的影响机制，并为企业优化融资决策提供科学依据。通过构建基于多层次回归分析的实证模型，结合2015年至2022年间中国A股上市公司的财务数据，系统分析了股权融资、债务融资及混合融资模式对资本成本的作用路径及其交互效应。研究表明，债务融资在特定条件下能够显著降低企业的资本成本，而过度依赖股权融资可能导致资本成本上升；同时，企业治理水平和行业特征对融资渠道选择与资本成本之间的关系具有显著的调节作用。此外，本研究首次引入动态资本结构调整视角，揭示了企业在不同生命周期阶段应采取差异化的融资策略以实现资本成本的最优控制。

Abstract
The selection of financing channels and the control of capital costs are core issues in modern corporate financial management, especially against the backdrop of increasing global economic uncertainty and evolving financial market structures. Researching these issues holds significant theoretical value and practical significance. This study aims to explore the impact mechanisms of different financing channels on corporate capital costs and provide a scientific basis for optimizing financing decisions. By constructing an empirical model based on multi-level regression analysis, this study systematically analyzes the effects and interaction effects of equity financing, debt financing, and hybrid financing models on capital costs using financial data from Chinese A-share listed companies between 2015 and 2022. The findings indicate that debt financing can significantly reduce corporate capital costs under certain conditions, while over-reliance on equity financing may lead to increased capital costs. Additionally, corporate governance levels and industry characteristics play a significant moderating role in the relationship between financing channel selection and capital costs. Furthermore, this study introduces a dynamic perspective on capital structure adjustment for the first time, revealing that companies should adopt differentiated financing strategies at different stages of their life cycle to achieve optimal control of capital costs.
