【摘要】：随着我国电子商务网站的迅猛发展，复制于美国Groupon模式的国内团购网站，经过了近三年的发展和探索，在我国已出现“千团大战”的局面。这种集合了电子商务、社交网络和广告平台三种功能于一身的团购网站，成为中国互联网领域最热门的商业模式之一。如何来评判一个团购网站是否处于良好的运行状态，目前我国的研究理论较少，大部分还是以主观判断方法来辨别一个团购网站的优劣。因此，本文意在从客观的角度，选用DEA方法，构建团购网站的评价体系，来综合评价团购网站的效率。本文选取了我国25家具有代表性的团购网站，从网站自身的建设方面来选取投入指标和产出指标，共14个。但根据DEA理论中的“拇指法则”规定，决策单元的个数不能少于投入、产出个数总和的两倍。又采用改进的主成分分析方法，在不失代表性的前提下，，来选取投入和产出指标。最后选取了具有代表性的3个投入指标和4个产出指标，提高了模型的评判效率。接着通过DEAP软件得出评判结果，对结果进行分类和分析。并给出了相应的改进投影，给团购企业提出相应建议，和消费者以选择标准。
[Abstract]:With the rapid development of E-commerce websites in China, the domestic Groupon model has been replicated in the United States. After nearly three years of development and exploration, there has been a "Thousand Guild War" situation in China. This kind of group purchase website, which combines the functions of e-commerce, social network and advertising platform, has become one of the most popular business models in China's Internet field. How to judge whether a group purchase website is in a good state of operation? at present, there are few research theories in our country, most of them use subjective judgment method to distinguish the merits and demerits of a group purchase website. Therefore, the purpose of this paper is to evaluate the efficiency of group-buying websites by choosing DEA method from an objective point of view and constructing the evaluation system of group-buying websites. This paper selects 25 representative group-buying websites in our country, and selects input index and output index from the construction of the website itself, a total of 14. However, according to the rule of thumb in DEA theory, the number of decision making units should not be less than twice of the total number of inputs and outputs. The improved principal component analysis method is used to select input and output indexes without losing representativeness. Finally, three representative input indexes and four output indexes are selected to improve the evaluation efficiency of the model. Then the evaluation results are obtained by DEAP software, and the results are classified and analyzed. The corresponding improvement projection is given, and suggestions are given to the group buying enterprises and consumers to select the standards.
