  • 人教版高中政治必修1市场配置资源教案

    人教版高中政治必修1市场配置资源教案

    教师点拨:这则材料说明,市场调节有其局限性,单纯的市场调节具有自发性、盲目性、滞后性等缺点。市场调节不是万能的。社会生活中有很多领域和产品不能用市场来调节,如国防、治安、消防等产品的供给问题,枪支弹药、麻醉品等都不能让市场来调节。市场调节具有自发性、盲目性、滞后性。自发性:由于市场调节是在价值规律自发作用下进行的,在利益驱动下会产生一些违反市场原则的行为,如制造、销售假冒伪劣商品,大量排放废水、废气破坏环境,窃取他人智力成果等等。盲目性:由于人们不可能完全掌握生产各方面信息及其变化趋势,致使决策带有一定的盲目性。如某种商品有利可图则一哄而上,反之则一哄而退,从而造成资源浪费和消费得不到充分满足。滞后性:由于市场价格的形成和传递有一个过程,一旦传递到生产经营者手中进行生产调整,就有一个时间差,致使市场调节带有滞后性,成为一种事后调节。
