Derived demand意思

"Derived demand" is an economic term that refers to the demand for a good or service that is derived from the demand for another good or service. In other words, the demand for a particular product is dependent on the demand for another product.

For example, the demand for crude oil is a derived demand because the demand for crude oil is derived from the demand for the products that are made from it, such as gasoline, diesel, and plastics. If the demand for these products increases, the demand for crude oil will also increase, as more crude oil will be needed to produce these products.

Another example is the demand for steel. The demand for steel is derived from the demand for the products that are made from it, such as cars, buildings, and appliances. If the demand for these products increases, the demand for steel will also increase.

Derived demand is an important concept in economics because it helps to explain how changes in the demand for one product can lead to changes in the demand for other products. It also helps to explain how changes in the supply of one product can lead to changes in the supply of other products.
