经济效益是经济活动投入和产出的对比关系。这里所说的投入,也就是我们通常所说的人力、财力、物力的投入,即所谓耗费。所说的产出,也就是指“产出”的有效成果,亦即获益。一般来说,在正常情况下,有投入就会有产出,只有投入而无产出的情况当然也有,那就是发生了彻底的损失。产出大于投入为正效益。投入越少,产出越多,效益也就越高。反之,投入大于产出,为负效益。投入越多,产出越少,效益也就越低。一般认为只有物质生产和经济部门讲究经济效益,并作为对其评价生产和经营活动业绩或考核的主要指标。但是,经济效益并不仅限于物质生产和经济部门,在非物质生产单位和部 Economic efficiency is the contrast between economic activity input and output.
