基于DEA模型的河南地区物流企业投入产出效率分析

摘要

建立评价物流投入产出的指标，基于DEA的C2R和C2GS2模型，分析研究了2012年河南地区17个城市的物流投入产出效率。结果表明，DEA总体无效的城市有10个，河南地区物流投入产出纯技术平均效率、纯规模平均效率以及总体平均效率分别是0.78、0.90、0.72。说明物流效率偏低的主要原因是纯技术效率偏低，并对DEA总体无效的城市提出了物流业发展建议。%In this paper, we built the indexes to evaluate logistics input and output, then relying on the C2R and C2GS2 models, analyzed the logistics input-output efficiency of the 17 cities in the Henan area for the year 2012, reached some revealing conclusions, and accordingly, at the end, gave suggestions to help the cities with generally invalid DEA score.
