The factors of price change in economics are determined by the relationship between supply and demand. On the one hand, due to the continuous international demand for oil, the demand for oil has been great. On the other hand, because the world's major oil-producing areas are all in the Middle East, this region is also a war-torn region, such as Iraq and Iran, which cannot supply oil continuously, making the oil supply gap very large. At the same time, APEC, the oil exporting organization, restricted oil supply, and international oil prices are expected to continue to rise.
