参考答案:
采用费用比较法。 NAV(进口)=30×1.1+0.2(P/A,10%,20)+3(P/F,10%,10)-30×5%(P/F,10%,20)=30×1.1+0.2×8.514+3×0.3855-1.5×0.1486=35.63(万元) NAV(国产)=25×1.1+0.4(P/A,10%,20)+0.1(P/G,10%,10)+0.1(P/G,10%,10)(P/F,10%,10)+3(P/F,10%,10)-25×5%(P/F,10%,20)=25×1.1+0.4×8.541+0.1×22.891+0.1×22.891×0.3855+3×0.3855-1.25×0.1486=35.06(万元) NAV(进口)>NAV(国产),所以应该选择国产设备。
