问题 问答题 简答题

随着手机、平板电脑内置摄像头的像素越来越高,越来越多的人在外出时舍弃了数码相机,而改用手机和平板进行拍照。为了挽回逐步丢失的市场,数码相机厂商们打起了价格战,不少知名的卡片式数码相机更是跌破1000元大关,如索尼、三星、尼康等品牌开展各种促销活动,竞争尤为激烈。运用“价格变动的影响”的有关知识,分析数码相机降价带来的影响。

答案

参考答案:

(1)价格变动会影响生活消费,引起需求量的变动。数码相机降价,会引起人们对它需求量的增加。

(2)价格变动会影响生产经营,会调节产量,数码相机降价可能使生产者因获利减少而缩小生产规模;会调节生产要素的投入,可能使生产者在生产中采用成本更低的生产要素

解析:

本题要求学生运用“价格变动的影响”的有关知识,分析说明数码相机降价带来的影响。本题的切口不大,直接考查学生对价格变动影响的相关知识的理解与记忆。通过分析本题材料,材料中并没有关于“数码相机降价带来影响”方面的表述。解答本题学生要努力回忆教材基础知识,从商品价格变动对生活消费、对生产经营两个方面的影响去分析说明。关于商品价格变动对生活消费的影响,学生可从商品价格与其需求量的负相关关系入手,说明数码相机降价会引起人们对它需求量的增加;关于商品价格变动对生产经营的影响,学生可从价格下降影响生产经营者的利益,说明数码相机降价会促使生产者缩小生产规模以及在生产中采用成本更低的生产要素。

考点:本题考查价格变动影响的相关知识。
