14、他人带来机会成本。2.用图形说明一国居民购买住房的增加对宏观经济的影响。参考答案：（1）购买住房为投资需求，它会影响总需求。（4分）（2）投资增加会引起总需求增加，总需求曲线向右方移动，由AD1移动到AD2。（4分）（3）变动的结果是GDP增加（由Y1增加为Y2），物价水平上升（由P1上升为P2）。（4分）（4）作图3分。3 在下列情况下，VCD影碟机的市场需求或需求量会发生什么变化？并解释其原因。（1）电影院票价从10元下降为5元。（2）政府加大了对盗版影碟的打击力度，盗版碟几乎没有了。（3）生产影碟机核心部件的工厂发生大火，半年内无法恢复生产。（4）生产影碟机的技术发生了突破性进步。参考答

15、案：（1）需求减少。到电影院看电影与看是替代品，替代品之间，其价格和需求同方向变动。电影院票价从10元下降为5元，就会导致对影碟机的需求减少。 （4分）（2）需求减少。盗版影碟与是互补品，互补品之间，其价格与需求反方向变动。政府加大了对盗版影碟的打击力度，盗版影碟少了，正版影碟的价格会上涨，从而会引起VCD影碟机的市场需求减少。 （4分）（3）需求量减少。因为生产影碟机核心部件的工厂发生大火，半年内无法恢复生产，会导致影碟机的供给减少，从而引起影碟机价格上升，使影碟机的需求量减少。（4分）（4）需求量增加。因为生产影碟机的技术发生了突破性进步，导致影碟机的供给增加，从而会引起影碟机的价格下降，

16、使需求量增加。（3分）4.简要说明决定经济增长的因素。参考答案：经济增长是GDP或人均GDP的增加。决定经济增长的因素主要有：（1）制度：是一种涉及社会、政治和经济行为的行为规则，决定人们的经济与其他行为，也决定一国的经济增长。制度的建立与完善是经济增长的前提。建立适应社会主义经济的制度；（5分）（2）资源：是经济增长的源泉，包括劳动力和资本。增加人力资本投资、提高人口素质。（5分）（3）技术：技术进步在经济增长中的作用，体现在生产率的提高上，即同样的生产要素投入量能提供更多的产品。技术进步主要包括资源配置的改善，规模经济和知识的进展。技术进步对我国经济增长的意义。（5分）5 .工资的变动是如

17、何通过替代效应和收入效应来影响劳动供给的？参考答案：（1）每个人的时间可分为两部分：工作与闲暇，一个人多少时间用于工作或闲暇取决于工资。（2）工资的变动通过替代效应和收入效应来影响劳动供给。替代效应指工资增加引起的工作对闲暇的替代，随着工资的增加，替代效应使劳动供给增加。另一方面，随着工资和收入的增加，人们对闲暇的需求也增加，增加闲暇必定减少劳动时间，这是工资增加引起的收入效应，收入效应使劳动供给随工资增加而减少。（3）替代效应和收入效应对劳动供给起着相反的作用。如果替代效应大于收入效应，则随着工资增加，劳动供给增加。如果收入效应大于替代效应，则随着工资增加，劳动供给减少。工资作为劳动的价格决

18、定了劳动供给政策。6 .国防、钢铁厂的污染、特大企业的存在都会引起市场失灵，它们各自引起市场失灵的原因是什么？应该如何解决？参考答案：（1）国防之所以会引起市场失灵，是因为它是一种公共物品。（2）钢铁厂的污染之所以会引起市场失灵，是由于外部性的存在。（3）特大企业会引起市场失灵，是由于垄断的存在。可以用政府干预来解决这些问题：国防由政府提供；污染可以使用立法或行政手段，或者采用经济或市场手段；垄断政府可以用价格管制、反垄断法或国有化来消除垄断。请您务必删除一下内容，O(_)O万分谢谢！2015年中央电大期末复习考试小抄大全，电大期末考试必备小抄，电大考试必过小抄Indonesia has em

In China, childrens illustration books have a history of just 100 years and their development can be divided into four stages. From early

34、1900s to mid 1900s, a large number of books and magazines with illustrations appeared with the fast development of the modern publishing industry. The illustrationarts at that time were a mixed genre of Chinese traditionalpaintings and the westernstyle, and most of the stories originate from the fun

35、damental changes that China experienced after the collapse of Qing Dynasty (1644-1911), the warlord struggles and the war against the Japanese invasion.
