基于DEA模型的我国城市水务企业经营绩效评价研究

我国城镇化进程的日益深化以及环境污染的日益严峻,使得科学评价并提升城市水务企业经营绩效成为当务之急。基于企业类型的维度,从城市水务企业区域分布、数量分布及综合实力等方面选取了12家代表性企业,运用DEA模型对其2012-2014年度的经营绩效进行了评价。结果表明:2012~2014年样本水务企业的整体绩效水平不高,其中有6家经营绩效达到最优水平,有5家纯技术效率与规模效率无效同时存在,其余1家纯技术效率有效而规模效率无效。另外,不同类型的水务企业经营绩效存在着差距,民营企业优于国有企业;基于评价结果提出了“国有企业应加强技术研发与提高管理效率、民营企业应积极开拓市场以及建立两类水务企业的利益共同体”等政策建议,以期提升水务企业经营绩效。
