1. The international natural gas price refers to the futures price, not the spot price. The crude oil used by refining enterprises can only be the oil mined in the past, not the oil to be mined in the future. Therefore, the impact of international crude oil prices on refined oil prices has a lag period.

2. Natural gas price is not only related to natural gas price, but also influenced by many factors such as market supply and demand, personnel cost, transportation situation, energy policy, water and electricity supply, etc. Crude oil is not the only factor that affects the price of refined oil.
