摘　　要：在构建科技投入产出综合指标体系的基础上，提出了一个基于熵权和灰色关联分析的科技投入产出效率评价模型。该模型应用熵权法确定各评价指标的客观权重，克服了原始灰色关联中指标平权和专家赋值的不足。同时，熵权法与灰色关联分析法相结合充分利用了各指标的全部信息，且充分发挥了灰色关联适合具有一定灰度小样本事件的优势。最后通过实例验证了该模型的有效性和适用性。We propose a new model of evaluation on the effciency of the input and output of science and technology based on entropy and gray relevant analysis. Entropy is used to determine the weight of assessment indicators, which remedy the insuffciency of average index weight and experts assigned index weight in original grey correlation. hTe combination of entropy weight with grey correlation analysis can fully utilize overall information of each index and give full play to the superiority of grey correlation that it is suitable for small sample events with a certain gray level. Finally, an example is used to prove the model is effective and applicable.
