航空行业Aviation Industry

Aviation is a foundational strategic industry that "connects the world". Aircraft cross mountains, rivers, seas, and borders, carrying people, goods, capital, technology, and culture to every corner of the globe. Civil air transport is the artery of international trade and people-to-people exchange, and also the intersection of high-end manufacturing (aero-engines, avionics, composite materials) and independent innovation (the domestically produced large aircraft). China has built the world's second-largest civil aviation market, with its fleet size, passenger throughput, and international route network all ranking among the world's top; at the same time, the C919 trunk airliner entering commercial operation and the ARJ21 regional jet being delivered in batches mark a historic breakthrough in China's "independent manufacturing".

Evaluating an airline cannot be "revenue-only"—large airlines easily post revenues of over a hundred billion yuan, yet their profit margins are generally thin; nor can it be "fleet-only"—low-cost carriers have modest fleets but stand on higher profitability efficiency and operational innovation; one must also look at its ability to "connect the world" (international routes) and its contribution to "independent manufacturing" (the domestically produced large aircraft). This index does not copy the positions of any public list; instead, it returns to underlying public data (operating revenue, fleet size, profit margin, market capitalization, domestically produced large aircraft/independent manufacturing, and international routes), independently building a "Scale + Quality + Innovation + Contribution" four-dimensional proprietary algorithm to comprehensively evaluate about 21 of China's most representative aviation enterprises (covering the full spectrum of the three major airlines, private full-service carriers, low-cost carriers, regional airlines, air-cargo carriers, and domestically produced aircraft manufacturers).

Evaluation results: Air China, China Southern Airlines, China Eastern Airlines, Spring Airlines, and COMAC rank in the top five, while Air China, China Southern Airlines, China Eastern Airlines, Spring Airlines, COMAC, Hainan Airlines Holding, XiamenAir, Juneyao Airlines, SF Airlines, and China Cargo Airlines enter the top ten. Overall, the three major airlines with the largest fleet and revenue scale and the widest international route network firmly occupy the top positions; the manufacturer focused on independent development of the domestically produced large aircraft enters the first tier thanks to a full score on the Innovation dimension; private carriers standing on high profit margins and low-cost models, and air-cargo enterprises distinguished by high-profit cargo and smart logistics, follow closely behind; regional and local airlines rank lower because of relatively limited scale and international connectivity. This ranking is based on approximate values from public common knowledge (marked "subject to official sources"), referring to listed companies' annual reports, the Civil Aviation Administration of China, IATA, and aircraft manufacturers' public delivery data; it is permanently free and public and provided for research and reference only.

The value of an aviation enterprise has the dual attributes of "commercial operation" and "national strategic infrastructure". This algorithm accordingly constructs a four-dimensional framework:

Each indicator is first min-max normalized into [0,1] (revenue and market capitalization are log-transformed before normalization), then weighted and summed, and finally multiplied by 100 to obtain a 0~100 score:

Here x′ denotes the normalized value of indicator x: x′ = (x − x_min) / (x_max − x_min); log₁₀ is the common logarithm, used to weaken the top-tier monopoly of revenue and market capitalization. The four-dimension weights sum to 1, ensuring that the index stably falls within 0~100.

The weight design follows "contribution first, equal emphasis on scale and innovation, and steady quality": international routes (Contribution) carry the highest weight of 0.30, reflecting aviation's essential mission of "connecting the world"; Scale and Innovation are 0.25 each—Scale reflects carrying capacity, and Innovation reflects the "national treasure" status of independent manufacturing; Quality is 0.20, with revenue and market capitalization log-transformed, both rewarding high-profit private/cargo carriers and avoiding "market-cap-only" thinking. Within the Scale and Quality dimensions, indicators are equally weighted at 0.5, keeping the model simple and reproducible.

Operating revenue, net margin, and market capitalization use approximate common-knowledge values from listed companies' annual reports (mainly the 2023-2024 reporting period) and public data from Wind, East Money Choice, and CNINFO, with unlisted enterprises' market capitalization being an approximate valuation; fleet size refers to the CAAC's "Statistical Bulletin on the Development of the Civil Aviation Industry", the Planespotters/IATA fleet databases, and each company's disclosures; the domestically produced large aircraft/independent manufacturing score refers to COMAC's public delivery and development progress for the C919/ARJ21/C929 and airlines' introduction of domestically produced aircraft; the international-route score refers to the CAAC's international-route approvals and each company's route-network disclosures. All data are uniformly marked "subject to official sources". This model does not include operational details that are difficult to quantify uniformly, such as safety records, punctuality, load factor, unit costs (ASK/CASK), and frequent-flyer scale, and the approximate values contain errors; the ranking is for research and reference only.
