摘 要
企业内部控制的有效性评价是现代企业管理中的重要议题，尤其在经济全球化和监管要求日益严格的背景下，如何科学评估内部控制质量成为学术界与实务界的共同关注点。本研究基于COSO内部控制框架，结合我国企业实际情况，构建了一套系统化的内部控制有效性评价体系。研究旨在通过量化分析方法，揭示企业内部控制的关键影响因素及其作用机制，为提升内部控制水平提供理论支持与实践指导。研究采用定性与定量相结合的方法，首先对COSO框架的核心要素进行分解，并设计了涵盖控制环境、风险评估、控制活动、信息沟通及监督等维度的评价指标体系；其次，运用层次分析法（AHP）确定各指标权重，并结合模糊综合评价模型对企业内部控制有效性进行综合评估。通过对多家上市公司的实证分析，研究发现当前企业在内部控制建设中普遍存在控制环境薄弱、风险评估不足以及监督机制不健全等问题。研究结果表明，基于COSO框架的评价体系能够有效识别内部控制缺陷并提出针对性改进建议。本研究的主要创新点在于将经典理论与本土化实践相结合，提出了适用于中国情境的内部控制评价模型，同时引入模糊数学方法增强了评价结果的科学性和可操作性。这一研究成果不仅为企业优化内部控制提供了具体路径，也为监管部门制定相关政策提供了参考依据，具有重要的理论价值和实践意义。

Abstract: The evaluation of the effectiveness of internal control is a crucial issue in modern enterprise management, particularly in the context of economic globalization and increasingly stringent regulatory requirements. How to scientifically assess the quality of internal control has become a shared concern for both academia and practice. This study constructs a systematic evaluation system for the effectiveness of internal control based on the COSO Internal Control fr amework, taking into account the actual conditions of enterprises in China. The aim is to reveal the key influencing factors and their mechanisms of internal control through quantitative analysis methods, thereby providing theoretical support and practical guidance for enhancing the level of internal control. By combining qualitative and quantitative approaches, the study first decomposes the core elements of the COSO fr amework and designs an evaluation indicator system covering dimensions such as control environment, risk assessment, control activities, information communication, and monitoring. Subsequently, the Analytic Hierarchy Process (AHP) is employed to determine the weights of each indicator, and a fuzzy comprehensive evaluation model is used to conduct an overall assessment of the effectiveness of internal control. Through empirical analysis of multiple listed companies, the study finds that enterprises generally face issues such as a weak control environment, insufficient risk assessment, and an incomplete supervisory mechanism in the construction of internal control. The results indicate that the evaluation system based on the COSO fr amework can effectively identify internal control deficiencies and propose targeted improvement suggestions. The main innovation of this study lies in integrating classical theory with localized practice, proposing an internal control evaluation model suitable for the Chinese context, and introducing fuzzy mathematical methods to enhance the scientific rigor and operability of the evaluation results. This research not only provides specific pathways for enterprises to optimize their internal control but also offers reference for regulatory authorities in formulating relevant policies, demonstrating significant theoretical value and practical implications.
