基于DEA-SBM模型的我国快递公司运营效率评价

Evaluation of China’s Express Delivery Companies Operational Efficiencies Based on DEA-SBM Model

摘要: 本文应用DEA-SBM模型对快递公司的运营效率进行评价，解决了因传统DEA模型径向和相同比例变化限制导致的高估快递公司运营效率值的问题，得到相对更加科学客观的快递公司运营效率值。最后，本文根据DEA-SBM模型的计算结果针对DEA无效的快递公司给出了投入指标和产出指标调整建议，助快递公司改进自身运营效率。

Abstract: This paper applies the DEA-SBM model to evaluate the operational efficiencies of express delivery companies, solving the problem of overestimating the operational efficiencies of express delivery companies due to the limitations of traditional DEA models in radial and proportional changes, and obtaining a relatively more scientific and objective operational efficiencies of express delivery companies. Finally, according to the calculation results of DEA-SBM model, this paper gives the input index and output index adjustment suggestions for DEA ineffective express delivery companies, which helps these express delivery companies to improve their operational efficiencies.
