食用油价格上涨主要由供求关系决定。当供小于求的时候,将导致供应商品的价格上涨,而食用油在短期不是个弹性商品,也就是说食用油的替代品很少,消费者不能够使用其他的产品来替代,从而导致食用油价格上涨。 The price of cooking oil is mainly determined by the relationship between supply and demand. When the supply is less than demand, it will lead to the price increase of the supply of goods, while the edible oil is not a flexible product in the short term, that is, there are very few substitutes for edible oil and consumers can not substitute other products, resulting in consumption Oil prices rise.
