问题 单项选择题

2006年,某农场棉花生产中的某些经济参数如下表所示:

根据上述资料,回答下列问题。

采用因素分析法分析每个因素对肥料成本变动的影响程度时,正确的替代是。 

A.单位面积施肥量×播种面积×单价

B.单位面积施肥量×单价×播种面积

C.播种面积×单价×单位面积施肥量

D.播种面积×单位面积施肥量×单价

答案

参考答案:D

解析:替代的排列顺序是:先数量指标,后质量指标;先主要因素,后次要因素。播种面积属于数量指标,单位面积施肥量也是数量指标,播种面积变动的空间更大,对肥料成本变动的影响也较大,所以属于主要因素。价格属于质量指标,故把单价放在后面。所以答案是D。
