Abstract: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.
