ABSTRACT
The COVID-19 has had a great impact on the global air transport industry. This paper analyzes the impact on China's air economic operation, including the current situation, challenges and problems of the regulation mechanism. A warning system for the economic operation of air passenger transport industry is conducted. With the help of warning lights, it reflects the degree of hotness or coldness of economic operation in 2011-2020.In addition, the study establishes the BP neural network forecast model to predict the economic operation of civil aviation industry in the next three years, and proposes the specific early warning management mechanism from five aspects. The conclusion of this study provides a strong support for guiding the civil aviation industry to prevent economic operation risks and improving the anti-vulnerability and resilience of the development of China's civil aviation industry. © 2021 IEEE
