1、经济师考试中级经济基础科目考前复习指导：统计指数篇重点、难点讲解及典型例题考点一指数的概念和分类狭义地讲，指数是用于测定多个项目在不同场合下综合变动的一种特殊相对数。目前普遍应用的是加权指数。【例1多选题】按照计入指数的项目多少不同，指数分为()。A.加权指数B.简单指数C.个体指数D.质量指数E.综合指数【答案】CE【解析】本题考查指数的分类。按照计入指数的项目多少不同，指数分为个体指数和综合指数。【例2单选题】下列指数中属于质量指数的是()。培训搜px.wangxiao.so培训网提示您A.商品销售额指数B.股票价格指数C.商品销售量指数D.产品产量指数【答案】B【解析】本题考查指数的分类
2、。质量指数反映事物质量的变动水平，如价格指数、产品成本指数等。所以选项B属于质量指数。考点二加权综合指数加权综合指数是通过加权来测定一组项目的综合变动情况。【例3单选题】下列各项中，属于帕氏数量指数的是()。【答案】C【解析】本题考查帕氏质量指数和数量指数的一般计算公式。分别是：【例4.单选题】下列各项中，属于拉氏物价指数的是()。【答案】B【解析】本题考查拉氏质量指数和数量指数的一般计算公式。分别是：考点三指数体系【例5单选题】某企业2009年的工资总额比2008年上升了20%，职工平均人数比2008年下降了10%，则2009年的职工平均工资比2008年()。A.上升30%B.上升33.3%
3、C.上升40%D.下降30%【答案】B【解析】本题考查指数体系的分析与应用。【例6单选题】某企业总生产费用今年比去年上升50%，产量增加25%，则单位成本提高了()。A.25%B.20%C.2%D.87.5%【答案】B【例7多选题】某商场2008年的总销售额为86000元，2009年为90000元，商品价格上涨10%，与2008年相比，则()。A.商品销售量指数为95.14%B.总销售额指数为104.65%C由于价格上涨使总销售额增加了8182元D.由于商品销售量下降使总销售额减少了8182元E.总销售额增加4000元【答案】ABCE【解析】本题考查指数体系的分析与应用。考点四几种常用的价格指
4、数(一)零售价格指数我国编制的价格指数中，与人民生活关系最为密切的是商品零售价格指数和居民消费价格指数。我国零售商品价格指数编制中的主要问题包括：(1)代表规格品的选择。在编制价格指数时，只能选择部分具有代表性的商品。(2)典型地隧的选择。典型地区的选择既要考虑代表性，也要注意类型上的多样性以及地区分布上的合理性和稳定性。(3)商品价格的确定。对所选代表性商品使用的足全社会综合平均价。(4)权数的确定。我国目前的零售价格总指数足采用加权算术平均形式计算的，其权数是根据上年商品零售额资料，并根据当年住户调查资料予以调整后确定的。(5)指数的汁算。从1985年1月起，我国开始采用部分商品平均价格法
5、计算全社会商品零售价格总指数。其计算公式为：式中，k为个体指数或各层的类指数，w为各层零售额比重权数。【例8多选题】我国目前编制的价格指数中，与人民生活关系最为密切的是()。A.农业生产资料价格指数B.商品零售价格指数C.固定资产投资价格指数D.居民消费价格指数E.农产品收购价格指数【答案】BD【解析】本题考查价格指数。与人民生活关系最为密切的是商品零售价格指数和居民消费价格指数。(二)消费价格指数我国称为居民消费价格指数1.概念居民消费价格指数是反映一定时期内城乡居民所购买的生活消费品价格和服务项目价格的变动趋势和程度的一种相对数。居民消费价格指数可就城乡分别编制城市居民消费价格指数和农村居
6、民消费价格指数，也可就全社会编制全国居民消费价格总指数。2.作用(1)能够反映城乡居民所购买的生活消费品价格和服务项目价格的变动趋势和程度。(2)能够反映通货膨胀的状况。通货膨胀的严重程度一般用通货膨胀率来反映，通货膨胀率一般以居民消费价格指数来表示。其计算公式为：(3)反映货币购买力变动。货币购买力是指单位货币能够购买到的消费品和服务的数量。居民消费价格指数的倒数就是货币购买力指数，其计算公式为：(4)反映对职工实际工资的影响。利用消费价格指数可以将名义工资转化为实际工资，其计算公式为：【例9单选题】某地居民的消费价格指数为105%，则当地的货币购买力指数为()。A.5%B.20%C.95.
7、2%D.102%【答案】C【解析】本题考查货币购买力指数的计算。货币购买力指数=1/居民消费价格指数=1/105%=95.2%。(三)股票价格指数1.股票价格的影响因素及公式正常情况下，股票价格通常与两个直接因素相关：预期股息和银行存款利息率。.2.股价平均数股价平均数是股票市场上多种股票在某一时点上的算术平均值，一般以收盘价来计算。其计算公式为：式中，Pi为第i种股票的收盘价，n为样本股票数。因股票市场上股票交易品种繁多，股价平均数(股票价格指数也一样)只能就样本股票来计算。但所选择的样本股票必须具有代表性和敏感性。3.股票价格指数股票价格指数是反映某一股祭市场上多种股票价格变动趋势的一种相
8、对数，简称股价指数，其单位一般以“点”表忝.即将基期指数作为100，每上升或下降一个单位称为“1点”。股票价格指数的计算一般以发行量为权数进行加权。【例10单选题】某人购买了上市公司股票1000股，每股票面金额10元，预期每年可以获6%的股息，而当时银行存款的年利率为5%，贷款利率为6%，如果没有其他因素影响，一年后此人购买的每股股票价格是()元。A.5B.8C.10D.12【答案】D【解析】本题考查股票价格的计算。每股股票价格=106%/5%=12(元)。Winger Tuivasa-Sheck, who scored two tries in the Kiwis 20-18 semi-fi
