[案例三]
[背景]
某省重点水利工程项目计划于2009年12月28日开工,由于工程复杂,技术难度高,一般施工队伍难以胜任,业主自行决定采取邀请招标方式。于2009年9月8日向通过资格预审的A、B、C、D、E五家施工企业发出投标邀请书。该五家施工企业均接受了邀请,并于规定时间2009年9月20~22日购买了招标文件。招标文件中规定,2009年10月18日下午4时为投标截止时间,2009年11月10日发出中标通知书。
在投标截止时间前,A、B、D、E四家企业提交了投标文件,但C企业于2009年10月18日下午5时才送达投标文件,原因是路途堵车。2009年10月21日下午由当地招标投标监督管理办公室主持进行了公开开标。
评标委员会成员由7人组成,其中当地招标投标监督管理办公室1人,公证处1人,招标人1人,技术、经济方面专家4人。评标时发现E企业投标文件虽无法定代表人签字和委托人授权书,但投标文件均已有项目经理签字并加盖了单位公章。评标委员会于2009年10月28日提出了书面评标报告。B、A企业分列综合得分第一名、第二名。由于B企业投标报价高于A企业,2009年11月10日招标人向A企业发出了中标通知书,并于2009年12月12日签订了书面合同。
[问题]

C企业和E企业的投标文件是否有效分别说明理由。

答案

参考答案:C企业的投标文件应属于无效标书。因为C企业的投标文件是在招标文件要求提交投标文件的截止时间后才送达的,为无效投标文件,招标人应拒收C企业的投标文件。E企业的投标文件应属于无效标书。因为E企业的投标文件没有法定代表人签字和委托人的授权书。

单项选择题

It is no longer just dirty blue-collar jobs in manufacturing that are being sucked offshore but also white-collar service jobs, which used to be considered safe from foreign competition. Telecoms charges have tumbled, allowing workers in far-flung locations to be connected cheaply to customers in the developed world. This has made it possible to offshore services that were once non-tradable. Morgan Stanley’s Mr. Roach has been drawing attention to the fact that the "global labour arbitrage" is moving rapidly to the better kinds of jobs. It is no longer just basic data processing and call centres that are being outsourced to low-wage countries, but also software programming, medical diagnostics, engineering design, law, accounting, finance and business consulting. These can now be delivered electronically from anywhere in the world, exposing skilled white-collar workers to greater competition.
The standard retort to such arguments is that outsourcing abroad is too small to matter much. So far fewer than lm American service-sector jobs have been lost to off-shoring. Forrester Research forecasts that by 2015 a total of 3.4m jobs in services will have moved abroad, but that is tiny compared with the 30m jobs destroyed and created in America every year. The trouble is that such studies allow only for the sorts of jobs that are already being off-shored, when in reality the proportion of jobs that can be moved will rise as IT advances and education improves in emerging economies.

Which of the following could be the best title for the text
[A] Business consulting.
[B] Blue-collar jobs.
[C] Non-tradable services.
[D] White-collar blues.


Alan Blinder, an economist at Princeton University, believes that most economists are underestimating the disruptive effects of off-shoring, and that in future two to three times as many service jobs will be susceptible to off-shoring as in manufacturing. This would imply that at least 30% of all jobs might be at risk. In practice the number of jobs off-shored to China or India is likely to remain fairly modest. Even so, the mere threat that they could be shifted will depress wages.
Moreover, says Mr. Blinder, education offers no protection. Highly skilled accountants, radiologists or computer programmers now have to compete with electronically delivered competition from abroad, whereas humble taxi drivers, janitors and crane operators remain safe from off-shoring. This may help to explain why the real median wage of American graduates has fallen by 6% since 9000, a bigger decline than in average wages.
In the 1980s and early 1990s, the pay gap between low-paid, low-skilled workers and high-paid, high-skilled Workers widened significantly. But since then, according to a study by David Autor, Lawrence Katz and Melissa Kearney, in America, Britain and Germany workers at the bottom as well as at the top have done better than those in the middle-income group. Office cleaning cannot be done by workers in India. It is the easily standardised skilled jobs in the middle, such as accounting, that are now being squeezed hardest. A study by Bradford Jensen and Lori Kletzer, at the Institute for International Economics in Washington D. C., confirms that workers in tradable services that are exposed to foreign competition tend to be more skilled than workers in non-tradable services and tradable manufacturing industries.
