文章利用C2 W模型提供的经典DEA模型的生产函数背景,研究串联网络结构和并联网络结构DEA模型的生产理论背景,得出网络DEA模型是真正"打开黑箱"的效率评价方法,为评价纵向一体化企业的效率及研究此类企业的生产决策问题提供了非参数分析方法。本文结论为网络DEA模型在经济分析中的应用提供了重要的理论支持。
C2W Model provided the production function explanation for the classic DEA.Basing on this result,this paper studied the production theory for network DEA models.The result showed that network DEA models could to tally open the black box.So that it could be used to evaluate efficiency of vertical integration firm and be a nonparametric method for the firms' decision.This paper provided an important theoretical support for using network DEA to economic analysis.
