基于模糊Borda组合评价法的电力行业上市公司经营绩效评价

组合评价的建模技术可以降低复杂系统的信息不完备性,而把模糊理论与组合思想统一在一起的模糊组合评价方法,对复杂系统的评价更贴近现实.首先利用中国上市公司2012年第一季度财务报表的有关数据,分别采用TOPSIS法、主成分分析法和因子分析法,对沪深股市中主营业务是电力的53家上市公司的经营业绩进行了综合评价和排序;其次,用非参数的Spearman等级相关系数检验法,验证了三种评价方法的一致性;最后,建立了模糊Borda组合评价模型,应用该模型对这53家企业的经营绩效重新进行了综合评价和排序,其结果更加科学、合理.

Comprehensive Evaluation of Listed Companies in Power Industry on the Operation Performance Based on Fuzzy Borda Combination Method

The modeling technology of combination evaluation reduces the information imperfectness of complex system.However,the fuzzy combination evaluation method unifying the Fuzzy Theory and combination makes the evaluation of the complex system more realistic. The paper,firstly,analyzes the data from thefirst quarter financial reportof Chinese listed companies in 2012,by adopting the Topsis evaluation method,Principal Component Analysis and Factor Analysisand then it comprehensively evaluates and ranks the operating performance of the 53 electric power companies listed on the Shanghai and Shenzhen stock markets. Secondly,the article verifies the consistency of the three evaluation methods through the nonparametric Spearman correlation coefficient test.Finally,the Fuzzy Borda Combination Evaluation Method have been established and applied to re-evaluate and reorder the operating performance of the 53 enterprises which makesthe result more scientific and reasonable.
