Vocabulary is the least stable part of any language.

随着我国人民收入水平的不断提高，“汽车梦”成为“中国梦”的重要组成部分。2000年以来，中国家用汽车的消费量以每年20%的速度增长。2013年1月23日发布中国《汽车社会蓝皮书》称 ，“2012年中国已经正式进入‘汽车社会’，每百户家庭私人汽车拥有量超过了20辆，5年后私人汽车保有量会翻一番”。家用汽车销量的猛增，带动了了我国汽车工业的发展，2010年，中国汽车的产量超过1800万辆，成为世界第一汽车制造大国。同时，随着能源价格的上涨和生态文明理念的普及，消费者对节能环保汽车需求愿望越来越强烈，在这种形势下，新一轮新能源汽车、混合动力汽车的研发竞争在汽车制造企业之间已经激烈地展开。方兴未艾的汽车消费带动了与汽车有关的广告、保险、金融、维护等行业的兴起与繁荣，拉动了我国经济的发展。

结合材料，运用“消费对生产的反作用”的知识分析汽车消费的积极作用。（12分）
