摘要

In order to achieve maximum profits and get more consumer surplus ,many airlines are implementing the system multistage ticket price .Appling the method of data envelopment analysis ,using the malmquist index ,researches are made on efficiency evaluation of system of multistage ticket price to the 20 routes of Shandong Airlines .Trough empirical re-search ,there are 12 routes are DEA invalid in these 20 routes .That is to say ,the system of multistage ticket price to these 12 routes still needs to be adjusted .At the same time ,by decomposing the malmquist index ,factors that affect the efficiency of system of multistage ticket price implemented by airlines can be known according to the visual date .There are 9 routes are the result of the structure of multistage ticket price ,and 7routes are due to price reason .%为实现利润最大化，目前很多航空公司都实行多级票价体系，以获得更多的消费者剩余。引入数据包络分析法，利用malmquist指数，针对山东航空公司20条航线进行了多级票价的效率评价研究，通过实证发现，这20条航线中，有12条尚未达到DEA （date envelopment analysis ）有效，即多级票价体系尚需调整。同时，通过分解malmquist指数，可以从数据直观地看出影响航空公司多级票价体系效率的因素，其中9条是由于多级票价结构原因，7条是由于票价价位原因。
