问题 判断题

甲、乙是条件相同的相邻地块,甲地单价为1400元/m2,容积率为4,土地使用年限为40年;乙土地单价为900元/m2,容积率为2.5,土地使用年限为50年。若土地报酬率为6%,则以楼面地价来判断,投资甲地块较乙地块更经济。( )

答案

参考答案:

解析:(1)首先把甲、乙地块换算成楼面地价
甲的楼面地价=土地单价/容积率=1400/4=350元/m2,乙的楼面地价=900/2.5:360元/m2
(2)要比较甲、乙两地块价格的高低,需要将它们先转换为相同期限下的价格。为了计算方便,将它们都转换为无限年下的价格
V甲∞=V401/K40=350×(1+6)40/[(1+6)40-1]=387.69元/m2
V乙∞=V501/K50=350×(1+6)50/[(1+6)50-1]=380.67元/m2
则投资乙地块比甲地块更经济。

Support for renewable energy technology to figllt global warming is weakening in the face of

worldwide economic problems and the true scale of the carbon reductions required,a survey pub-

lished today has suggested.

Figures presented at the UN climate talks in Poznan,Poland,show that climate experts have

less faitll in alternative energy than they did 12 months ago.

The survey shows less support for wind energy,solar power,biofuels,biomass and hydrogen

energy as technologies with“high potential”to reduce carbon levels in the atmosphere over the next

25 years.

Eric Whan of Globesean,which carried out t}le survey of“climate decision makers”.said.

“As the climate crisis deepens they could be becoming less optimistic that individual technologies

may be able to solve the problem.’’

The survey,supported by groups including the World Bank,the United Nations Environment

Programme and the Pew Center for Global Climate Change,questioned l,000 senior figures across

governments,pressure groups and companies in 1 15 countries over the last few weeks.

Almost three—quarters of the experts agreed in the survey that“equitable(公平的,平等的)e—

eonomic growth and development and significant progress in combating(与…斗争)climate change

Call be achieved at the salne time.’’

Asked to rate the likely Success of low—carbon technologies in the mid—term,they showed

less confidence than a similar survey 12 months ago.Support for offshore wind farms,was down

61%from 65%last year.Solar electricity generation was rated as having high—potential by 66%of  respondents,down from 74%.Support for hydrogen power was 32%,down form 36%in 2007.

The respondents also warned that a deep recession(衰退)would make a new global deal on climate harder to achieve.Some 44%agreed that the current economic crisis will significantly delay orcompromise the“achievement of effective climate change agreements.’’
