补充资料:相关成本与非相关成本(relevantcostandirrelevantcost)
  成本按其发生是否与决策项目相关的分类。相关成本是指与制定决策方案有关的联影响的成本,例如当期是否接受一批订货,生产该批订货需要花费的各种成本,即为相关成本。如该批订货是一种特殊订货,即其价格低于以前生产这种产品的完全成本时,其相关成本就是生产该批产品的变动成本。如果生产该批订货需扩大生产能力时,相关成本就既包括生产的变动成本,还包括添置设备等所需的其他成本。机会成本、差量成本、现金支出成本、可避免成本等均属相关成本。

  非相关成本是指与制定决策方案并无影响的成本,因而在决策时可不予考虑。命名如接受特殊订货时,原有固定成本就属于非相关成本,因为即使不接受这批特殊订货,这些固定成本也会照样发生,当有几种方案可供选择时,各种方案都需发生的成本就是非相关成本,如采用不同的生产工艺组织生产时,构成产品实体的原材料在各种生产工艺过程中都要发生,所以这些原材料成本便是非相关成本。不可避免成本、沉落成本等属于不相关成本。
