Price Discrimination

Price discrimination is a microeconomic pricing strategy where identical or largely similar goods or services are transacted at different prices by the same provider in different markets. Price differentiation is distinguished from product differentiation by the more substantial difference in production cost for the differently priced products involved in the latter strategy. Price differentiation essentially relies on the variation in the customers' willingness to pay and in the elasticity of their demand.

價格歧視（Price discrimination）是獨占者對同一種物品向某些消費者收取的價格高於另一些消費者，或者對少量購買的消費者收取的價格高於大量購買的消費者。通常以消費能力、地區、急迫程度……等特性作為區分。
