基于DEA模型的水公用事业上市公司绩效评价

PERFORMANCE EVALUATION OF LISTED WATER UTILITIES COMPANIES BASED ON DEA MODEL

基于搜集的13家水公用事业上市公司2012—2014年经营绩效评价的相关指标数据,构建了数据包络分析(DEA)模型,对水公用事业行业的技术有效性和规模有效性进行分析,对企业的绩效进行评价。研究表明,阳晨B股、江南水务、国中水务、锦龙股份这4家公司3年来各项效率均处于较高水平,达到DEA有效;重庆水务、创业环保、洪城水业、首创股份的纯技术效率较高但规模效率相对较低,祥龙电业、钱江水利的规模效率较高但纯技术效率相对较低,瀚蓝环境、武汉控股、中山公用的各项效率均较低。最后对水公用事业上市公司提出了加强内部管理控制、提高经营管理效率、利用产业优势做大做强企业、立足主营业务提升竞争能力的建议。
