高一政治 2.1影响价格的因素学案

2.1影响价格的因素学案【学习目标】 1.了解影响商品价格的各种常见的具体因素。 2.理解商品供给与需求对商品价格的影响，知道价值规律的基本内容和表现形式。 3.理解商品价值与价格、劳动生产率与商品价值量的关系，分析社会必要劳动时间对于商品生产者的重要意义。 4.通过学习培养分析问题的能力、认清问题本质的抽象思维能力，从而提高参与经济生活的水平。【课前预习】一、供求影响价格 1．影响价格的因素。 (1)间接因素：引起价格变动和差异的因素有很多，如气候、时间、地域、生产条件、政策等，甚至宗教信仰、习俗等文化因素。各种因素对商品价格的影响，是通过改变该商品的供求关系来实现的。 (2)直接因素：商品的供求关系。 2．供求影响价格的表现。 (1)当商品的需求增加、供给减少，导致商品短缺时，价格上涨，于是出现“物以稀为贵”的现象。 (2)当商品的需求减少、供给增加，导致商品过剩时，价格下降，于是出现“货多不值钱”的现象。二、价值决定价格 1．价值与价格的关系。价值是价格的基础，价格是价值的货币表现。在其他条件不变的情况下，商品的价值量越大，价格越高；商品的价值量越小，价格越低。 2．商品价值量的决定因素。 (1)商品的价值量不是由各个商品生产者所耗费的个别劳动时间决定的，而是由社会必要劳动时间决定的。 (2)社会必要劳动时间的含义：是指在现有的社会正常的生产条件下，在社会平均的劳动熟练程度和劳动强度下，制造某种商品所需要的劳动时间。(3)社会必要劳动时间对商品生产者的意义：每个商品生产者用高于或低于社会必要劳动时间生产的商品，都只能按照社会必要劳动时间决定的价值量出售。因此，个别劳动时间低于社会必要劳动时间的，处于有利的地位；个别劳动时间高于社会必要劳动时间的，则处于不利的地位。这就促使商品生产者努力缩短生产商品所用的个别劳动时间，提高劳动生产率。 (4)社会劳动生产率与商品价值量的关系。若其他因素不变，单位商品的价值量与生产该商品的社会劳动生产率成反比。 3．价值规律及其表现形式。 (1)基本内容：商品的价值量由生产该商品的社会必要劳动时间决定，商品交换以价值量为基础实行等价交换。 (2)表现形式：商品价格受供求关系的影响，围绕价值上下波动。
