问题 单项选择题

内部收益率是考察投资项目赢利能力的主要指标,对于具有常规现金流量的投资项目,下列关于其内部收益率的表述中正确的是( )。

A.利用内插法求得的内部收益率近似解要大于该指标的精确解

B.内部收益率受项目初始投资规模和项目计算期内各年净收益大小的影响

C.内部收益率是使投资方案在计算期内各年净现金流量累计为零时的折现率

D.内部收益率反映项目自身的赢利能力,它是项目初期投资的收益率

答案

参考答案:B

解析:内部收益率是使投资方案在计算期内各年净现金流量的现值累计为零时的折现率。也就是说,在这个折现率时,项目的现金流入的现值和等于其现金流出的现值和。利用内插法求得的内部收益率近似解不一定大于该指标的精确解,也可能小于该指标的精确解。内部收益率的经济含义是投资方案占用的尚未回收资金的获利能力,它取决于项目内部。它并非项目初期投资的收益率。
