熵值法结合功效系数法的上市公司财务风险预警

Financial Risk Early Warning of Listed Companies Based on Entropy Value Method and Efficiency Coefficient Method

熵值法可以有效区分不同指标之间的重要性,功效系数法则可以对系列指标进行统一处理,二者结合使用可以提升评价准确性及灵敏度.在简单讨论熵值法及功效系数法原理后,对如何进行上市公司财务风险预警进行分析.本文以Y上市公司为例,通过其年度报告,选取财务指标及相关数据,结合使用熵值法、功效系数法,计算Y上市公司财务风险综合水平.研究结果表明:2011-2015年,Y上市公司财务风险指标得分呈下降趋势,其财务风险预警等级由"轻警"上升至"中警".

Entropy method can effectively distinguish the importance of different indicators, while efficacy coefficient method can deal with a series of indicators in a unified way. The combination of the two methods can improve the accuracy and sensitivity of evaluation. After briefly discussing the principles of the Entropy Method and the Efficiency Coefficient Method, this paper makes an analysis on how to carry out the financial risk early warning of listed companies. Take Y listed company as an example, through its annual report, select financial indicators and related data, and use the method of entropy and efficiency coefficient to calculate the comprehensive level of financial risk of Y listed company. The results show that from 2011 to 2015, the financial risk index scores of Y listed companies show a downward trend,and their financial risk early warning level rises from “light alarm” to “medium alarm”.
