基于熵值法-固定比例技术的机场运营效率计算新方法

A New Method for Calculating Airport Efficiency Based on Entropy Value Method-fixed Ratio Technique

机场运营效率研究对于实现我国民航事业持续健康发展有着重要意义。由于机场生产系统在大多数情况下包括不可替代的投入和不可转换的产出,传统方法不能准确计算机场运营效率,因此,文章提出了熵值法-固定比例技术(EFPR)方法分析机场的运营效率。固定比例(FPR)是一种用于输入不可替代、输出不可转换情况下的效率分析技术。同时,通过熵值法来定义FPR计算中每个标准的优先级权重。最后以中国部分机场为研究对象,分别计算机场的效率表现,并将其与传统数据包络分析方法 (DEA)结果进行比较。结果表明,熵值法-固定比例技术方法可以识别机场生产系统的异质性,其中货运量是机场产业最显著的产出参数,而机场客运量的分离度自2015年以来呈上升趋势。该方法可以有效识别高效率机场,具有更好的鲁棒性。

The study of airport operation efficiency is of great significance to achieve the sustainable health of China's civil aviation industry.Since the airport production system includes irreplaceable inputs and non-convertible outputs in most cases,the traditional methods cannot accurately calculate the airport operation efficiency,so this paper proposes the entropy value method-fixed proportion technique(EFPR)method to analyze the airport operation efficiency.Fixed proportional(FPR)is an efficiency analysis technique used in the case of non-substitutable inputs and non-convertible outputs.The entropy value method is also used to define the priority weights of each criterion in the FPR calculation.Finally,some airports in China are studied to calculate the efficiency performance of the fields separately and compare them with the traditional DEA results.The results show that the entropy method-fixed ratio technique approach can identify the heterogeneity of the airport production system,where cargo volume is the most significant output parameter of the airport industry,while the separation of airport passenger traffic has shown an increasing trend since 2015.Meanwhile,the method can effectively identify high-efficiency airports with better robustness.
