随机解释变量有几种情形？分情形说明随机解释变量对最小二乘估计的影响与后果？
正确答案: 随机解释变量有三种情形，不同情形下最小二乘估计的影响和后果也不同。
（1）解释变量是随机的，但与随机干扰项不相关；这时采用OLS估计得到的参数估计量仍为无偏估计量；
（2）解释变量与随机干扰项同期无关、不同期相关；这时OLS估计得到的参数估计量是有偏但一致的估计量；
（3）解释变量与随机干扰项同期相关；这时OLS估计得到的参数估计量是有偏且非一致的估计量。
第6题：
对于古文，历来有几种解释法？
正确答案:关于古文，迄今有三种说法，各执一端，均有所据。其一，从广义的、文字学的角度说，泛指甲骨文、金文、石鼓文、古匋文、古泉文和小篆等，这些，均属于古文系统，与秦汉以后的隶书、楷书为主的“今文”相对应而称之谓古文。其二，是指殷、周或更早的古代文字。如宋郭忠恕在其《汗简》一书中说：“鸟迹科斗，通谓‘古文’。”元郑杓《衍极》卷二《书要篇》刘有定注云：“自伏羲命子襄作六书，而黄帝后命苍颉制文字，下及唐、虞三代，通谓之‘古文’。”其三，专指晚周及六国所用的文字。后蜀林罕《字文偏旁·字序》说：“降及夏、殷、周，通谓古文，至宣王太史籀作《大篆》十五篇，与古文或异。七国分裂，篆与古文随其所尚。”近人王国维力主“战国时秦用籀文，六国用古文”的说法，认为“至许（慎）书所出古文，即孔子壁中书，其体与籀文、篆文颇不相近，六国遗器亦然。壁中古文者，周秦间东土之文字也。”对此，在他的《史籀篇疏证·序》中作了详细论证。

第8题：
(b) Good Sports Limited has successfully followed a niche strategy to date.
Assess the extent to which an appropriate e-business strategy could help support such a niche strategy.
(8 marks)
正确答案：
(b) Good Sports has pursued a conscious niche or focus differentiation strategy, seeking to serve a local market in a way that
isolates it from the competition of the large national sports good retailers competing on the basis of supplying famous brands
at highly competitive prices. Does it make strategic sense for Good Sports to make the heavy investment necessary to supply
goods online? Will this enhance its ability to supply their chosen market?
In terms of price, e-business is bringing much greater price transparency – the problem for companies like Good Sports is
that customers may use their expertise to research into a particular type and brand of sports equipment and then simply
search the Internet for the cheapest supply. Porter in an article examining the impact of the Internet argues that rather than
making strategy obsolete it has in fact made it more important. The Internet has tended to weaken industry profitability and
made it more difficult to hold onto operational advantages. Choosing which customers you serve and how are even more
critical decisions.
However the personal advice and performance side of the business could be linked to new ways of promoting the product
and communicating with the customer. The development of customer communities referred to above could be a real way of
increasing customer loyalty. The partners are anxious to avoid head-on competition with the national retailers. One way of
increasing the size and strength of the niche they occupy is to use the Internet as a means of targeting their particular
customers and providing insights into the use and performance of certain types of equipment by local clubs and users. There
is considerable scope for innovation that enhances the service offered to their customers. As always there is a need to balance
the costs and benefits of time spent. The Internet can provide a relatively cost effective way of providing greater service to
their customers. There is little in the scenario to suggest they have reached saturation point in their chosen niche market.
Overall there is a need for Good Sports to decide what and where its market is and how this can be improved by the use ofe-business.
