基于非期望产出的机场运营效率评价

传统的机场运营效率评价模型忽视了机场运营过程中航班延误、噪音及有害排放物等非期望产出带来的负面效应. 采用非参数方向距离函数法，构建基于非期望产出的机场运营效率评价模型. 针对我国长江三角洲多机场区域10个主要机场，对引入非期望产出前后运营效率进行对比分析，验证基于非期望产出的机场运营效率评价模型的有效性. 结果显示，非期望产出是评价机场运营效率不可缺少的关键因素之一；其次，非期望产出要素对机场运营效率产生非常显著的影响. 引入非期望产出后，我国机场运营效率和运营规模之间并不存在正相关性；最后为机场及航空公司管理者在权衡机场吞吐量和服务质量方面提供了相关建议和理论依据.

Undesirable output based evaluation of airports productivity

The traditional model of airports productivity evaluation ignored the impact of undesirable outputs such as delayed flights, noise, harmful emissions and so on. A non-parametric directional output distance function, rather than the traditional data envelopment analysis, was applied to construct an airport productivity evaluation model based undesirable outputs. The empirical research regarding 10 airports in Yangtze River Delta multi-airport region was performed to verify the model. The results show that undesirable output is one of the indispensable factors on airport productivity. Secondly, undesirable outputs affect the airport productivity significantly. There is non-positive correlation between airport productivity and airport size after considering the undesirable output. Finally, some suggestions of a balance between quantity and quality of outputs in the achievement of efficient outcomes for authorities are provided.
