中文摘要：

电商对实体超市经营模式带来了巨大冲击,但作为大型连锁超市的发展速度却不降反升。同时,原有BCC模型分析面板数据的方法存在忽视技术进步的弱点。因此,为更准确地探究其在迅速发展的态势下的经营效率的状况,运用广义DEA方法测算2008-2015年中国15家大型连锁超市的经营效率状况。分析结果表明：这15家企业平均综合效率呈波动状态,纯技术效率逐年上升。最后,根据实证分析结果提出了针对大型连锁超市提高经营效率的合理建议。

英文摘要：

E-commerce has had a huge impact on the business pattern of the physical supermarket.However,as the large chain supermarkets,their growth have not fallen back.At the same time,the original BCC model to analyze the panel data also has the disadvantage of ignoring technological progress.Therefore,in order to explore accurately the operational efficiency of them in the trend of rapid development,this paper uses the generalized DEA method to measure China 15 large chain supermarkets operational efficiency during 2008-2015.The results show that the average comprehensive efficiency of these 15 enterprises is fluctuating,and the pure technical efficiency is increasing year by year.Finally,this paper puts forward some reasonable suggestions for improving operational efficiency of the large chain supermarkets.
