1. Aviation kerosene price increase: Aviation kerosene is one of the main operating costs of airlines, and its price fluctuation directly affects the profitability of airlines. In recent years, due to the fluctuation of international oil price and the change of global supply and demand, the price of aviation kerosene has risen many times, which has increased the cost pressure of airlines. Therefore, it is necessary to pass on part of the cost by increasing the fuel cost of mechanical construction.
2. Increased cost of infrastructure construction: As an important transportation infrastructure, the airport needs constant maintenance, upgrading and expansion. These infrastructure construction costs are usually borne by the airport management, and the cost is recovered by charging airlines for fuel for building aircraft. If the cost of infrastructure construction increases, the fuel cost of machinery construction may also increase.
3. Policy adjustment: In order to balance the development of aviation industry and other modes of transportation, the government may adjust the fuel cost of aircraft construction. For example, in order to encourage air travel, the government may reduce the fuel cost of aircraft construction; On the contrary, in order to control the environmental pollution and traffic congestion caused by air travel, the government may increase the fuel cost of aircraft construction.
4. Changes in market demand: Market demand is also a factor that affects the fuel cost of mechanical construction. In the case of strong demand for air travel, airlines may increase the fuel cost of aircraft construction to achieve higher profits. In the case of weak demand, airlines may reduce the fuel cost of aircraft construction to attract more passengers to fly.
It should be noted that the adjustment of fuel cost for aircraft construction is usually decided by airlines, airport management and relevant government departments through consultation. In the process of price increase, airlines and airport management need to fully consider the market demand and passengers' affordability, so as to avoid the adverse impact of excessive price increase on the aviation industry and passengers.
