电商企业经营管理绩效评价--基于沪深两市上市公司的实证分析

The Performance Evaluation on the Operation and Management of E-business Enterprises——An Empirical Analysis Based on Listed Companies in China

将数据包络分析的BCC模型和超效率模型结合起来,通过DEAP2.1和DEA-Solve-LV软件对在沪深两市上市的22家电商企业的经营管理绩效进行实证分析。结果表明,在BCC模型下22家电商企业中有10家的经营效率达到DEA有效,整体而言电商企业的纯技术效率是比较高的,大多数规模无效的电商企业处于规模报酬递增阶段,具有较大发展空间;SE-DEA模型可以对BCC模型下DEA有效的电商企业进行比较分析,并且这些综合效率大于1的电商企业在SE-DEA模型下依然可以通过改进其投入要素组合达到最优的生产前沿面。

This article combed BCC model and Super-Efficiency model and used DEAP2.1 and DEA-Solve-LV. The results show that the overall efficiencies of 10 among the 22 e-business enterprises selected reach the DEA valid state in the BCC model. The pure technical efficiency of these selected e-business enterprises is relatively high, and most of the scale invalid enterprises are in the stage of increasing returns to scale. Those DEA efficient e-business enterprises are of no difference under the BCC model, while using SE-DEA model can make a comparative analysis of these companies. Additionally, those enterprises which overall efficiency is larger than 1 could still improve their investment factors to achieve optimal production frontier in SE-DEA model.
