已知 2001-2005 年部分国民经济主要指标如下表。要求： 1.分别计算 2001 和 2005 年的投资率和消费率。 2.不考虑价格因素，计算 2005年 GDP增长率，并 分析投资和消费的拉动作用。 3.简要分析净出口对 2005 年 GDP增长的影响。
答：
1、通常是指一定时期(年度)内总投资占国内生产总值的比率。投资率能更确切地观察建设与生产、建设与消费之间的关系。同时，投资率有利于国际比较。
投资率 = 总投资额 / 国内生产总值生产额× 100%=总投资额 / 国内生产总值使用额×100%=固定资本形成总额/支出法
GDP消费率又称最终消费率，是指一个国家或地区在一定时期内(通常为1 年)的最终消费(用于居民个人消费和社会消费的总额)占当年GDP的比率。它反映了一个国家生产的产品用于最终消费的比重，是衡量国民经济中消费比重的重要指标。
消费率 =最终消费支出总额 / 国民收入
2001年的投资率是 37213/108972，消费率是 66878/108972 .
2005年的投资率是 88604/186701，消费率是 96918/186701
2、2005年的 GDP增长率 =186701/160280—1
投资的拉动作用就是( 88604-70477)/ (186701-160280)
消费的拉动作用就是( 96918-87033)/ (186701-160280)
3、生产法的 GDP=各部门增加值之和收入法的 GDP=各部门固定资产折旧 +各部门劳动者报酬+各部门生产税净额 +各部门营业盈余支出法的国内生产总值=最终消费 +资本形成总额 +净出口
GDP=186701，资本形成总额 =79560，最终消费支出 =96918
所以：净出口 =10223，净出口对 GDP增长的影响就是 10223/186701
