机场数字化的碳减排效应:理论机制与实证检验

Carbon emission reduction effect of airport digitization:theoretical mechanism and empirical test

本文以中国民航机场为研究对象,以2019年的截面数据为时间窗口,构建了机场数字化与碳减排关系的模型。从能力进阶演化与互补的视角,分析建设规模及行政区划视角下数字化与碳排放的关系,并检验了数字化影响机场碳排放的作用机理。研究发现:机场数字化可以显著抑制碳排放,数字化水平每提高1%,碳强度降低0.108%;数字化的碳减排效应具有明显地区差异,但没有形成规模效应。数字化主要通过高效配置资源来提高管理水平和提升旅客服务满意度,从而实现碳减排。本文研究结论可为数字技术推进民航碳达峰、碳中和提供理论支撑和经验证据。

Taking civil aviation airports in China as the research object and using cross-section data of 2019 as the time window,a model of the relationship between airport digitization and carbon reduction is constructed.From the perspective of capability advanced evolution and complementarity,the relationship between digitization and carbon emissions under the viewpoint of construction scale and administrative division is analyzed,and the mechanism of digitization effect on airport carbon emission is tested.It is found that airport digitization can significantly suppress carbon emissions,and carbon intensity decreased 0.108%with every 1%increase in digitization level.The carbon emission reduction effect of digitization has obvious regional differences,while there is no scale effect.Digitization mainly realizes carbon emission reduction through improvement of management level and passenger service satisfaction by efficient resource allocation.The research conclusion of this paper can provide theoretical support and empirical evidence for propulsion of carbon peak and carbon neutrality in civil aviation based on digital technology.
