摘要
为探究海港型城市机场的运行效率,采用三阶段DEA(数据包络分析)模型及Malmquist生产力指数分别从静态、动态两个角度分析。选取沿海地区14座海港型城市的机场并选取内陆地区城市的18家机场进行对比研究。结果表明:样本机场间运行效率值差距较大;海港型城市机场的总体效率比内陆城市机场低9%;90%机场处于规模报酬递增阶段,机场生产效率总体呈现增长趋势。因此,内陆城市机场可以通过不断提升技术,改建或扩建提升效率;海港型城市机场应该充分发挥其规模优势。
In order to explore the operating efficiency of harbor-type city airports,the three-stage DEA(data envelopment analysis)model and Malmquist productivity index are used to analyze from static and dynamic perspectives.The airports of 14 seaport cities in coastal areas and 18 airports in inland cities are selected for comparative study.The results show that there is a large gap in operational efficiency among the sample airports,the overall efficiency of harbor city airports is 9%lower than that of inland city airports,90%of the airports are in the stage of increasing returns to scale,and the overall airport production efficiency shows an increasing trend.Therefore,airports in inland cities can improve efficiency through continuous upgrading of technology,reconstruction or expansion,airports in harbor-type cities should give full play to their scale advantages.
