深入剖析工业设计与企业科技活动的隶属关系，在此基础上获取工业设计投入产出值的区间范围。将C-OWG算子集结数据方法与效率评价方法相结合建立了适合评价投入产出为区间值的DEA模型。在此基础上构建了工业设计资本累积存量计算模型。运用模型详细分析了顺德制造企业工业设计投入产出效率。并根据实证分析结果对提高顺德制造企业工业设计效率给出了建议。

Through the analysis of scientific and technological activities affiliation with industrial design in depth, input-output interval-valued of industrial design was gained. And the data gathering methods of C-OWG operator was combined with efficiency evaluation methods to establish a DEA model which was suitable for evaluating interval-valued input-output. Then the model for calculating the capital accumulation of industrial design input was built. A detailed analysis of Industrial Design input-output efficiency of manufacturing enterprises in ShunDe was achieved by the model established above. On this basis, some proposal related to improving the efficiency of industrial design was put forward in the end of the paper.
