摘要:

鉴于当前严峻的水资源利用现状,通过建立DEA模型,从投入产出角度出发,以农业用水、生产用水、生活用水、全社会劳动者及固定资产投资为输入指标,以GDP为输出指标,对兰州市2000—2008年水资源利用效率进行评价。结果表明,9年中DEA有效年份占55%,投入冗余和产出不足均为0,即投入和产出达到最优状态。在DEA无效年份中投入冗余,存在资源浪费情况,要素利用效率不足,但效率在逐渐提高,可以通过DEA投影结果对其进行改进,实现资源的最优配置。

关键词: DEA模型 ;水资源, 效率;可持续发展

Abstract:

In view of the severe water resource utilization, this paper establishes a DEA model, taking agricultural water, production water, living water, labors and fixed asset as input and GDP as output, evaluates Lanzhous water utilization efficiency during 2000—2008, of which valid DEA years is 55%, without investment redundance and scant output, meaning an optimized input/output. During the year when DEA is invalid, resources are wasted, the elements utilization efficiency is not enough but increasing. DEA projection results can achieve an optimized resources allocation.

Key words: DEA model, water resources, efficiency, sustainable development
