The airport industry, which is heavily regulated, has shown interest in improving performance by increasing non-aeronautical revenues (NAR) to cope with changes in the aviation environment, including trends toward liberalization and privatization. This study uses panel data from three separate years (2012, 2014, and 2016) to analyze how a high NAR share might affect airport charging policies and explores the impact of NAR on landing charges of global airports grouped by type of aircraft. The data was collected from 137 airports worldwide, and generalized least squares regression was performed by including data obtained from the ATRS (Air Transport Research Society) Global Airport Benchmarking Reports. The results indicate that an increase in the NAR share has a statistically significant negative effect on airport charges. This study provides meaningful implications from an empirical analysis of how a change in an airport’s business model, such as increasing the NAR share, might affect airport charges. This study’s results are expected to encourage international airports to be more active in promoting commercial activities (e.g., duty-free shops) and pursue a pricing policy that can bring them a competitive advantage.

受到严格监管的机场行业已经表现出了通过提高非航空收入（NAR）来应对航空环境变化（包括自由化和私有化趋势）来提高绩效的兴趣。这项研究使用来自三个不同年份（2012年，2014年和2016年）的面板数据来分析较高的NAR份额可能会如何影响机场收费政策，并探讨NAR对按飞机类型分组的全球机场着陆费的影响。该数据是从全球137个机场收集的，并通过包括从ATRS（航空运输研究协会）全球机场基准报告中获得的数据来进行广义最小二乘回归。结果表明，NAR份额的增加对机场收费具有统计上显着的负面影响。这项研究通过对机场业务模式的变化（例如增加NAR份额）如何影响机场收费的实证分析提供了有意义的启示。预期这项研究的结果将鼓励国际机场更加积极地促进商业活动（例如，免税商店）并奉行能够为其带来竞争优势的定价政策。
