Further Approach to the Sensitivity Analysis of DEA and Its Application
DEA灵敏度分析的进一步探讨与应用

One model of DEA(data envelopment analysis) sensitivity analysis is presented in this paper. Using this model, we developed the sufficient and necessary conditions to keep the classification of being efficient or inefficient when only one DMU changes. Nevertheless, the sufficient condition of keeping classification in the worst case is proposed. In the last section, an empiric example on measuring competitiveness performance of innovative firms is offered to verify the result. Thus, the proposed method is proved feasible and valid; competitiveness.
