摘要
自1978年以来，经过三十多年的改革开放, 随着社会经济的持续快速发展，我国经济已摆脱短缺状况，我国已经基本建立了比较完善的社会主义市场经济体系,由原来的卖方市场转变为现在的买方市场。因此,我国居民消费水平和消费结构的情况在很大程度上影响着国民经济的运营情况。消费、投资、净出口是拉动经济增长的“三驾马车”，近年来，我国国民经济持续快速发展，但居民消费对经济增长贡献却在逐步走低，居民消费的增长低于经济的增长，而其中农村居民的消费又更弱于经济的快速发展。占我国人口绝大多数的农村居民是有着很大消费潜力的一个群体,提升农村居民的消费水平，对于增加居民消费对经济增长的贡献份额，提高经济运行质量具有重要的现实意义和理论意义。
