财务柔性影响高新技术企业创新绩效的理论分析

A Theoretical Analysis of the Impact of Financial Flexibility on Innovation Performance in High-Tech Enterprises

摘要: 高新技术企业创新活动具有高投入、高风险、长周期、高信息不对称的典型特征，普遍存在着严重的融资约束以及研发投资中断风险。财务柔性是企业用较低的成本获得和调动财务资源、应对不确定性、把握投资机会的能力，是企业持续创新的财务条件。文章在系统界定财务柔性与创新绩效内涵的基础上，结合国内外的相关文献，从融资约束理论、信息不对称理论、实物期权理论、组织冗余理论、委托代理理论等角度出发，提出财务柔性对创新绩效有“缓冲”和“赋能”两种作用机制。在此基础上，研究进一步构建经济学模型加以刻画：研发投资模型表明，财务柔性对研发投资的边际促进作用介于0和1之间，且随着融资约束程度的加大而增大，因而在信息不对称程度较高的高新技术企业中表现更为显著；最优柔性模型显示，由于持有成本和自由现金流代理成本的限制，财务柔性与创新绩效之间呈现倒U型关系，随着公司治理水平提高而扩大最优储备区间。因此，文章从企业动态适度储备、治理约束加强和外部融资生态改善这三个方面提出政策建议。

Abstract: The innovation activities of high-tech enterprises are characterized by high investment, high risk, long cycles, and severe information asymmetry, which expose them to tight financing constraints and the risk of R&D interruption. As the ability to obtain and mobilize financial resources at low cost to cope with uncertainty and seize investment opportunities, financial flexibility becomes a key financial condition supporting sustained innovation. Building on a clarification of the connotations of financial flexibility and innovation performance and a review of the literature, this paper integrates financing-constraint theory, information-asymmetry theory, real-options theory, organizational-slack theory, and agency theory to reveal a “buffering” and “empowering” dual mechanism. On this basis, the study further constructs economic models for characterization: an R&D investment model shows that the marginal effect of financial flexibility on R&D investment lies between 0 and 1 and increases with the severity of financing constraints, hence being more pronounced for high-tech firms; an optimal-flexibility model shows that, constrained by holding costs and free-cash-flow agency costs, the relationship between financial flexibility and innovation performance is inverted-U-shaped, with an optimal reserve interval that widens as corporate governance improves. Accordingly, the paper offers policy recommendations from three dimensions: dynamic and moderate reserve management by enterprises, strengthening of governance constraints, and improvement of the external financing ecosystem.
