论述题

(32分)阅读材料,回答下列问题。

世界贸易发展历史就是一部世界经济发展史,也是国际关系史的重要组成部分。阅读下列材料:

材料一:明清时代,面对近代国际贸易的不断发展,统治者坚持把贸易归入朝贡体系,“凡贡使至,必厚待其人,”对他们携带的货物,“皆倍偿其价”于是各国纷纷来“贡”,导致“岁时颁赐,库藏为虚”。但是,在朝贡贸易中,中国政府并不是无所要求,而是政治动机大于经济目的,力图造成“四海宾服,八方来仪”的宏大场面.

——《朝贡外交和朝贡贸易》   

材料二:l840年一位英国人说:  “关于我们对印度贸易的整个问题是他们是否能用他们的土地产物来偿付我们准备输出的工业品.”

1851年马克思在一篇《国际述评》说:“成千上万的美美船只开到中国,这个国家很快就为不列颠和美国廉价工业品所克斥,以手工劳动为基础的中国工业经不住机器的竞争.”

材料三:面对严重的经济危机,l930年美国国会通过法案,把890种商品进口关税提高近40%,由此引发了一场关税大战.到1932年,先后有七八十个国家采取报复措施,大幅度提高了关税.

为了用本国康价商品去攻破别国的关税壁垒,各国纷纷贬植货币.1931年,英国宣布英镑贬值30%,l934年,美国宣布关元贬值40%.资本主义世界货币制度和货币体系一片混乱,到1935年,逐渐分裂成若干区域性的、彼此对抗的货币集团,主要有英镑区、美元区、法郎区、日元区等.

——《世界史·现代史鳊》上卷

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.

To offshore services that were once non-tradable results from ______.
[A] the blue-collar job market
[B] the geographic location of the underdeveloped world
[C] the fierce competition among skilled workers
[D] the dive of telecoms fee


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.
