美国航空航天与国防行业：腾飞的引擎，全球航空发动机产业寡头格局、价值链与投资机遇

The aviation airbags market refers to the ecosystem of technologies, systems, and components involved in the development and integration of airbag-based safety solutions in aircraft cabins. These systems are engineered to deploy rapidly upon detecting an abnormal aircraft motion or crash impact, cushioning the passenger’s upper body and reducing trauma. This market includes airbag control modules, inflators, sensors, and integrated seat systems. Innovations in lightweight materials, sensor fusion, and predictive deployment mechanisms are driving new product development. The market is a convergence point for aerospace safety engineering, passenger ergonomics, and regulatory compliance, with a strong focus on minimizing injury risks without adding significant weight to the aircraft.

Cable cars are aerial lift systems that transport passengers or goods using cabins suspended from a moving cable. These systems are commonly used in urban transportation and tourism, offering efficient and scenic travel over challenging terrains and providing access to otherwise inaccessible areas.

Boat docks and lifts are a type of machinery that is used to lift and handle boats. This machinery helps in keeping the boats safe and sustaining their integrity by protecting them from corrosion and breakage. These machines are generally used for transporting boats between water at two different elevations and offer an alternative to the canal lock and the canal inclined plane. These machines find applications in household and commercial spaces. The global boat docks and lifts market comprises establishments that are primarily engaged in the manufacturing of docks, lifts, and related accessories.

301船舶法案：美国301法案听证会结束，按美法案规定，4月17日前会有具体措施出台。考虑货主反对意见较多，存在豁免部分集装箱 以外的船只的可能。如果落地政策严格程度超预期，班轮公司因航线调整码头拥堵造成运价飙升将利好集运，若不落地或政策严格程度 低于预期，船舶板块情绪压制或解除，利好船舶板块。

The market by value in this report is defined as the revenues that enterprises gain from goods and/or services sold within the specified market and geography.

Air sports equipment refers to the specialized gear and apparatus used in various air sports activities. These activities involve aerial maneuvers and often require equipment designed to ensure safety, performance, and enjoyment.

Drones are pilotless aircraft or flying robots, which are also referred to as UAVs. Drones fly autonomously or are controlled by an onboard computer. They can also be operated using a remote control from the ground. Commercial drones are those that are used in commercial sectors such as infrastructure, agriculture, energy, and public safety. The report does not include drones or related services that serve the military/defense segment.
