民用航空发动机是现代工业的科技高地、综合国力的象征，是我国构建“双循环”新发展格局的重要装备领域；我国相关行业起步较晚，正处于加速发展的关键时期，探讨民用航空发动机自主发展战略路径对推动交通强国、制造强国、航空强国建设具有重要价值。本文着眼民用航空发动机高质量自主发展，结合实地调研及深化研讨成果，系统梳理民用航空发动机的国际发展经验，分析我国民用航空发动机发展态势，识别内外部环境变化并洞察市场需求，凝练行业发展面临的迫切问题。针对“双循环”格局下民用航空发动机自主发展的“三步走”目标，论证提出了产业发展路径，即增强国内大循环内生动力和可靠性、提升产业链供应链韧性、形成“双循环”发展格局。研究建议，统筹布局未来绿色动力研发、构建飞发协调机制、加快形成多元支持模式、加强政策引导和支持，促进民用航空发动机产业稳健提升。

Civil aero-engine is the scientific and technological highland of modern industry and a symbol of the comprehensive national strength of a country; it is also crucial for constructing a new development pattern of dual circulation in China. The development of civil aero-engine industry in China started late and now it is in a critical period of development. Therefore, it is necessary to explore a strategic path for the independent development of the industry, thereby strengthening the transportation, manufacturing, and aviation sectors of China. Through field investigation and further discussion, experiences of other countries regarding aero-engine development are summarized and development status of aero-engines in China is analyzed. Moreover, existing problems of the aero-engine industry in China are examined while considering the development situation in China and abroad and focusing on market demand. The independent development of China’s aero-engine industry can be achieved by three steps and the three-step targets can be realized by promoting scientific and technological innovation capabilities, improving the industrial and supply chains, and encouraging international cooperation. Furthermore, the following suggestions are proposed: promoting the research and development of green power, establishing an aircraft – engine coordination mechanism, developing a multiple support mode, and strengthening policy support and guidance.
