Made questionnaire for therationality of index system, based on collected data of questionnaires to make factor analysis, todetermine the final evaluation index system.Secondly, according to analyze the existing research results of website appraisal, wesystematically contrast each assessment method, and then decide to take DEA (data envelopeanalysis) method as analysis method in this article. And define the input and output of DEAmodel of index system constructed.Finally, this article takes14portal websites, such as Sina, Tencent,163.com e.g., asresearch samples to evaluate website efficiency from angle of user. Besides, we take futureanalyze, named super efficiency DEA analysis, which can obtain the super efficiency ranking.Finally, analyzes the websites investment redundancy from the quota angle, and gives concretelycountermeasure and suggestion for enhance the website operation efficiency..
