问题 问答题

某建设项目计算期10年,其中建设期2年。项目建设投资(不含建设期贷款利息)1200万元,第1年投入500万元,全部为投资方自有资金;第2年投入700万元,其中500万元为银行贷款,贷款年利率6%。贷款偿还方式为:第3年不还本付息,以第3年末的本息和为基准,从第4年开始,分4年等额还本,当年还清当年利息。

项目流动资金投资400万元,在第3年和第4年等额投入,其中仅第3年投入的100万元为投资方自有资金,其余均为银行贷款,贷款年利率8%,贷款本金在计算期最后一年偿还,当年还清当年利息。

项目第3年的总成本费用(含贷款利息偿还)为900万元,第4年至第10年的总成本费用均为1500万元,其中,第3年至第10年的折旧费均为100万元。

(除特殊要求外,计算结果均保留两位小数)

[问题]

项目的投资额、单位产品价格和年经营成本在初始值的基础上分别变动±10%时,对应的财务净现值的计算结果见表4-1。根据该表的数据列式计算各因素的敏感系数,并对3个因素的敏感性进行排序。

表4-1 单因素变动情况下的财务净现值表   单位:万元

答案

参考答案:

计算各因素的敏感系数。

投资额:(1190-1300)/1300/10%=-0.85

单位产品价格:(320-1300)/1300/(-10%)=7.54

年经营成本:(550-1300)/1300/10%=-5.77

敏感性排序为:单位产品价格,年经营成本,投资额。

     The moon is the earth's largest and only natural satellite. A satellite is a small body that goes around a
planet. The first man-made satellite went into the orbit in 1957. By 1968 there were over three hundred
satellites in the orbit. Some satellites send back weather pictures. Others send out radio waves. Some
satellites are what we call "junk". In 1963, the United States put millions of small pieces of wire into orbit.
They were used to carry radio waves. Many of these wires may still be there. Some space junk was not
put in the orbit. For example, one piece of space junk is a glove lost by an astronaut!
     Space is very big. Does it matter if there is junk in the orbit? Many scientists think so. They say we
must pay much attention to how we use this new resource. They think anything man puts into space
should be made to come back to earth when its work is done. They say it's dangerous to have space junk,
because it's possible for spacecraft to collide with the junk.
