1. Supply change: The explosion of Jiangxi Chemical Plant caused the production or supply of petroleum and liquefied gas to be interrupted, which led to the decline of overall supply, which led to the shortage or tension of supply in the futures market, which led to the price increase.

2. Changes in demand: The explosion of Jiangxi chemical plant will lead to a decline in people's demand for oil and liquefied gas, such as reducing people's use of gasoline, diesel oil, liquefied gas and other fuels, or reducing people's consumption of liquefied gas, which will lead to a decline in price inertia in the futures market.
