An economic condition, similar to a duopoly, in which there are only two large buyers for a specific product or service. Members of a duopsony have great influence over sellers and can effectively lower market prices for their supplies. Also known as "buyer's duopoly".

指一种经济条件，类似于双寡头，在一种商品或服务的买卖中只有两个大买家。买方对卖方有重大影响，并且能影响供应的市场价格。也称为"买方的双头垄断" 。

For example, a town only has two operating restaurants. As a result there are only two employment options for waiters and chefs. The restaurant can offer lower wages because the restaurants have less competition for finding employees. The chefs and waiters have no choice but to accept the low pay, unless they choose not to work. This shows that firms that are part of a duopsony have the power not only to lower the cost of supplies, but also to lower the price of labor.

例如：一个镇上只有两家饭店。只有服务生和厨师这两个就业机会。饭店可以压低工资水平因为不难雇到人。服务生和厨师除了接受低工资别无选择，除非他们不想要工作。这表明处于垄断地位的公司不仅能降低供应价格，而且能降低劳动力的价格。
