The data envelopment analysis (DEA) is used to evaluate operation efficiency of 17 listed companies in China aviation industry from 2006 to 2011,and make longitudinal analysis for the operation efficiency.In addition,the reason of changing efficiency is dynamically evaluated by Malmquist productivity index.The empirical results show that average operation efficiency of 17 listed companies in China aviation industry is less than 1,which means that the operation activities of aviation industry exist diseconomies characteristic,technological progress efficiency is a major influenced factor.
The data envelopment analysis (DEA) is used to evaluate operation efficiency of 17 listed companies in China aviation industry from 2006 to 2011, and make longitudinal analysis for the operation efficiency. In addition, the reason of changing efficiency is likely evaluated by Malmquist productivity index . The empirical results show that average operation efficiency of 17 listed companies in China aviation industry is less than 1, which means that the operation activities of aviation industry exist diseconomy characteristic, technological progress efficiency is a major influenced factor.
