In the bright starry sky of the aviation manufacturing industry,
the C919 large passenger aircraft is undoubtedly a dazzling new star. It carries the dream of China's aviation industry and soars above the blue sky. Behind it is a huge and complex supply chain system, like a tightly interwoven net, which affects the whole body.
As of now
the domestic suppliers of C919 have reached 122 like stars, and state-owned enterprises are like the brightest stars in the night sky, accounting for more than half of the country with 67. Among them, the subsidiaries of China Aviation Industry Corporation are leading the way, with 24 subsidiaries deeply involved in it, firmly occupying the core position of the C919 project. They are like the backbone of the C919, the roc, supporting the steady progress of the entire project. From design and development to production and manufacturing, these state-owned enterprises can be seen in every link. With their deep technical accumulation, strong manufacturing capabilities, and unswerving determination, they contribute indispensable forces to the birth of C919.
It is worth mentioning that there are 13 Sino-foreign joint ventures active in the supply chain of C919, of which Sino-US joint ventures account for the majority. These joint ventures are like a bridge between domestic and foreign aviation technologies. By introducing foreign advanced technology and management experience and combining domestic industrial advantages, they have brought new vitality and innovation to C919. While improving the technical level of C919, they have also promoted exchanges and cooperation between the domestic and foreign aviation industries.
Of course, there are 104 foreign suppliers in the supply chain of C919. They come from all over the world, each with unique technology and products, to contribute to the grand project of C919. This also fully reflects the characteristics of global cooperation in the aviation manufacturing industry. No country can fight alone in such a complex project.
From the perspective of the localization rate, C919 has shown a gratifying side. In the raw materials and parts links, the degree of localization is high, reaching or even exceeding 50%. This means that China has considerable strength in the manufacturing of basic materials and parts, and can provide a solid foundation for C919. These domestic raw materials and parts, like the cornerstone of a building, firmly support the overall structure of C919. They are not only reliable in quality but also cost-controlled, providing strong support for the market competitiveness of C919.
However, we can also clearly see that in terms of airborne systems, especially power systems and avionics systems, foreign suppliers and Sino-foreign joint ventures account for a high proportion. This is like two small hills on the road ahead for C919. Although it temporarily blocks the pace of localization, it also points out the direction for us to move forward. There is a huge room for improvement and a vast market gap waiting for Chinese aviation people to explore and fill. The power system is the "heart" of the aircraft, and the avionics system is the "brain" of the aircraft. Overcoming the localization difficulties in these two key areas is of vital significance to improving the overall level of China's aviation industry.
The supply chain system of C919 covers all aspects from new materials, parts, and airframe manufacturing to airborne systems. It is like an ecosystem, and each link is closely connected and interdependent. This huge system not only reflects China's profound accumulation in the aviation manufacturing industry but also is the result of the hard work of countless aviation people over the years. It also shows the trend of global cooperation and localization going hand in hand. In the future, with the continuous advancement of China's aviation technology, we have reason to believe that the localization rate of C919 will continue to increase, and China's aviation industry will surely shine more brightly on the world stage and contribute more Chinese wisdom and strength to the development of the global aviation industry.
