中文摘要：

目前主要采用AHP或模糊综合评判法对投资项目进行评价，但这些方法仅能体现各投资项目的优劣程度，不能体现各投资项目的弱点以及无效的原因，并且指标权重的确定带有较强的主观性，很难排除人为因素带来的偏差。针对这一问题，本文提出了一种将数据包络分析和模糊理论相结合的投资项目评价方法。最后，通过实例分析证明，该方法简单实用，能够为企业进行项目投资决策提供有效的参考。

英文摘要：

At present,the most common evaluation method for investment projects is AHP or fuzzy comprehensive judgment, but all these methods can only reflect the quality of investment projects and can＇t reflect the weaknesses of investment projects and the causes of invalidity. Besides,the determination of index weight has highly subjectivity,and it is difficult to eliminate the bias caused by human factors. In order to solve this problem,this paper proposes an evaluation method for investment projects based on DEA and fuzzy theory. Finally, the case shows that the method is simple and practical,providing an effective reference for enterprises to make decisions on investment projects.
