基于DEA-Malmquist的国内通用航空上市企业经营绩效评价

Based on DEA-Malmquist Listed Domestic General Aviation Business Performance Evaluation

运用DEA-Malmquist指数法,对22家通用航空上市企业的指标数据进行了静态、动态效率分析。结果发现,2012年决策样本中有77%的通用航空上市企业综合效率小于1.000,纯技术效率和规模效率都没有达到最优状态,导致其综合效率低下,没有成为样本标杆企业;2008-2012年只有5家企业的全要素生产率指数大于1.000,所有样本企业都出现了技术退步的现象。由此可以看出,技术落后成为提高我国通用航空上市企业经营绩效水平的主要阻碍,技术创新成为现实选择,并在最后给出相应建议。

Based on the 22 listed companies in general aviation indicator data ,DEA-Malmquist index method for static and dynamic efficiency analysis was used . The results showed that in 2012 77% of the sample making general aviation listed companies was less than 1 .000 in comprehensive efficiency ,and the pure technical efficiency and the scale efficiency had not reached the optimal state ,resulting in low efficiency of its comprehensive sample did not become a benchmark for enterprises . The period of 2008-2012 only five companies TFP index greater than 1 .000 ,all the sample enterprises emerged in the phenomenon of regression techniques . Therefore , the technology regression in general aviation companies was the major obstacle .Consequently ,the technology progress would be a realistic choice in improving our operating performance level And finally the corresponding recommendations were given .
