price-fixing的含义为“价格固定”，具体指：为某一商品涨价、降价、定价、限价或稳定价格之目的且具有该效果而组成的联合。由竞争的厂商合作固定价格水平或范围，但自然的市场力量则不会如此。此类协议违反了《谢尔曼反托拉斯法》[Sheman Antitrust Act]。该法规定的价格固定有两种：水平价格固定和垂直价格固定。前者指竞争者之间的协议，如竞争之零售商零售商之间的协议；后者指在控制零售价格，如制造商与零售商之间的协议。州律师协会提出并执行的最低收费表亦属于《谢尔曼反托拉斯法》禁止的价格固定行为。

为了更好的理解该词的含义，以下是该词的英文释义：Price fixing is an agreement between participants on the same side in a market to buy or sell a product, service, or commodity only at a fixed price, or maintain the market conditions such that the price is maintained at a given level by controlling supply and demand.

如：

1.If there were only two airlines on every route, tacit collusion between them would probably keep prices high but not so high as if there were a single airline or an explicit price-fixing agreement. 

假设在每条线路上都只有两家公司，他们可能会心照不宣的勾结，但不会使得价格高到犹如一加航空公司操控或者是基于一个明显的价格协议。

2.Illegal ACTS prohibited by the regulations include price-fixing agreements and excluding or limiting competition through abuse of dominant market share, according to the regulations.

根据该法规，签订限价协议以及滥用市场垄断地位来排除或限制竞争等违法行为将被禁止。
