    人教版高中政治必修1财政收入与支出教案

    (2)财政收支平衡是指当年财政收入等于支出,或收入大于支出略有节余,或支出大于收入略有赤字。(3)财政赤字是指当年财政支出大于财政收入的部分。赤字意味着要靠借债过日子,有可能导致社会总供给与总需求不平衡,引发通货膨胀。必须把财政赤字控制在一定范围之内。教师活动:请同学们思考教材75页虚框内问题。学生活动:阅读课本,认真思考,积极发言教师点评:发行国债可以增加财政收入,扩大政府投资,刺激消费需求,促进经济发展。但是国债发行规模过大,会增加政府还债负担,不利于经济的长期稳定发展。在经济生活中,国家可以通过调整财政收入支出控制经济运行。当经济增长缓慢时,采取积极的财政政策,增加经济建设支出,减少税收,以刺激需求,拉动经济增长。反之,当经济发展过热时,采取紧缩性财政政策,减少财政支出,增加税收,以抑制社会需求,降低通货膨胀率,给经济降温。

  • 人教版高中政治必修1税收及其种类教案

    人教版高中政治必修1税收及其种类教案

    教师总结:近二十多年来,我国个人所得税的征收发展迅速,这也反映了我国经济水平、人民生活收入有了较大提高。与增值税的计税方法不同,个人所得税采用累进税率的计税办法,就是个人所得越高,税率越高,纳税人个人收入越多,缴纳个人所得税越多。这一特点从教材83页个人所得税税率表上可以看出。教师点拨:个人所得税的计算办法是分段计算的,个人收入800元以内不计税,多余800元以上部分,按不同税率分段计税。请同学们计算教材所列题目。学生活动:计算。应税所得额:4000元;不超过500元部分:25元;500――2000元部分:150元;2000――4000元部分:300元;累计所得税:475元教师活动:同学们想一想,这样计算个人所得税有什么意义呢?学生活动:认真思考,回答问题教师点拨:有利于增加财政收入,有利于调节个人收入分配,实现社会公平。(三)课堂总结、点评

    (3)人民币外汇牌价:我国通常采用100单位外币作为标准,折算为一定数量的人民币。如果用100单位外币可以兑换更多的人民币,说明外汇汇率升高;反之,则说明外汇汇率跌落。教师活动:大家知道汇率是经常变动的,为什么汇率经常变动?我国在美国、日本等国再三施加压力的情况下,为什么保持汇率稳定,人民币不升值?学生活动:学生就老师提出的问题去阅读教材;然后展开讨论,并回答(4)保持人民币币值稳定的意义教师点评:影响汇率变动的因素主要有:外汇的供求关系、通货膨胀(或紧缩)率的差异、经济增长率、利率水平、国家货币当局的干预与管制、市场预期、外汇投机活动等。外汇在国家经济发展和国际贸易中具有重要的作用:通过汇率的升降调节进出口贸易;可以影响国际资本的流动方向和数量;可以影响国内物价水平;影响外汇储备的实际价值等。
