在交通运输行业向“数字化、绿色化、融合化”转型的新要求下，交通、能源与信息三大领域的深度融合正成为推动航空运输数字化转型以实现高效运营和可持续发展的关键路径。为应对当前航空运输业存在的运营效率低下、旅客体验欠佳及能耗过高的问题，首先系统梳理了三大领域融合的支撑政策、研究热点及动向、区域实施方案。然后结合案例，深入解析了三者融合驱动航空运输数字化转型的具体机制，包括协同重构、数据赋能与目标耦合。在对数字化转型内容剖析的基础上，提出了“数据驱动-流程重构-决策创新-价值闭环”的数字化转型参考路径，并设计了相应的“交通-能源-信息融合一体化平台”，通过四层架构推动转型落地实施。最后，探讨了航空运输数字化转型中的数字孪生技术、物联网与区块链等五大关键技术，并运用PESTEL模型分析了面临的挑战，包括政策协同性不足、投资回报周期过长等问题。基于研究结果得出以下结论：①航空运输数字化转型本质上是以技术创新与业务重构双轮驱动，推动行业实现高质量、可持续发展的过程，其关键在于构建“交通-能源-信息”三网融合的数字化底座；②提出了数字化转型参考路径，并设计了一体化平台，通过四层架构推动转型落地实施，为未来航空运输数字化转型提供参考。

Under the new requirements of the transportation industry′s transformation "digitization, greening, and integration", the deep integration of transport, energy, and information is becoming a key path to promote digital transformation of air transportation to achieve efficient operation and sustainable development. To address the issues of low operational efficiency, poor passenger experience, and high energy consumption in the current air transportation industry, the supporting policies, research hotspots and trends, regional implementation plans for these three major areas′ integration were first systematically reviewed at first. Then, combined with case studies, the mechanism of the integration of the three driving the digital transformation of air transportation was deeply analyzed, including collaborative refactoring, data empowerment, and target coupling. Based on the analysis of digital transformation content, a digital transformation path for reference was proposed, structured as "data driving"-"process reengineering"-"decision innovation"-"value loop". Correspondingly, a "transport-energy-information integrated platform" was designed, featuring a four-layer architecture to facilitate the implementation. Finally, five key technologies in the digital transformation of air transportation, including digital twin technology, the internet of things and blockchain, were discussed. The PESTEL model was used to analyze the challenges faced, including insufficient policy synergy and long investment return cycles. Based on the research results, the following conclusions can be drawn: ①The essence of digital transformation in air transportation is to drive high-quality and sustainable development of the industry through technological innovation and business restructuring, and the key lies in building a digital foundation for the integration of the three networks, namely "transport-energy-information". ②A reference path for digital transformation has been proposed, and an integrated platform has been designed to promote the implementation of transformation through a four-layer architecture, providing reference for future research on digital transformation of air transportation.
