Air transport gives necessary transportation companies for financial improvement; in the meantime, its operation requires huge useful resource inputs into the air transport sector (ATS). To be able to guarantee sustainable improvement of air transport trade, enhance the utilization effectivity of sources, and coordinate the event of the ATS and the macroeconomy, the operational effectivity of the trade needs to be evaluated precisely. Nevertheless, few research have analyzed the operational efficiency of ATSs throughout completely different areas. This research subsequently constructs an index system and utilized a three-stage information envelopment evaluation (DEA) method, which considers numerous regional environmental elements and statistical noise, to judge regional ATS operational efficiency. China’s 30 provincial ATS operational efficiencies in yr 2017 are empirically evaluated utilizing the proposed mannequin. The empirical outcomes present that completely different ranges of environmental elements, reminiscent of regional GDP, openness, technical markets, technological improvement, and consumption, pose numerous influences on provincial ATS operational effectivity in China. Operational efficiency analysis outcomes eliminating these environmental results within the third stage present appreciable variations with that stage 1 outcomes. As well as, corresponding improvement technique implications in several provinces and areas are put ahead in accordance with the analysis outcomes.
