Tradability
（重定向自Tradable good）
Tradability is the property of a good or service that can be sold in another location distant from where it was produced. A good that is not tradable is called non-tradable. Different goods have differing levels of tradability: the higher the cost of transportation and the shorter the shelf life, the less tradable a good is. Prepared food, for example, is not generally considered a tradable good; it will be sold in the city in which it is produced and does not directly compete with other cities' prepared foods. Haircuts and massages are also non-tradable.
