基于CFPS2010、2012、2014和2016数据，跨年份考察我国农村居民家庭消费总量、消费结构、消费支出弹性和消费价格弹性的动态变化，发现农村居民家庭收入节节攀升、消费水平大幅提高、消费结构明显改善。包含人口学变量的QUAIDS模型估计结果表明，收入提高、健康状况改善、户主受教育水平提升等均会促进家庭消费；从消费支出弹性看，食品、衣着、交通通信消费长期缺乏弹性，教育文化、医疗保健消费长期富有弹性，高收入阶层家庭大部分消费支出弹性高于低收入阶层家庭；从消费价格弹性看，教育文化、居住消费等长期富有弹性，大部分类别消费的自价格弹性波动不大，各类交叉价格弹性在不同时期对食品类消费的影响均不大，医疗保健消费受其余各类消费的影响有降低趋势。

Based on the CFPS data in the years of 2010, 2012, 2014 and 2016, the paper examines the dynamic changes in total consumption, consumption structure, consumption expenditure elasticity and consumption price elasticity of the Chinese rural households over the years, and finds the significant increase in the income of rural households and the improvement in the consumption level and the consumption structure. The estimation results of the QUAIDS Model (Quadratic Almost Ideal System) with demographic variables show that the increase in family income, the improvement in health and educational attainment of the household heads are likely to promote household consumption. In terms of consumption expenditure elasticity, the consumption of food, clothing, transportation and communication has long been inelastic while the consumption of education, culture and healthcare elastic, and a majority of high-income families have higher consumption expenditure elasticity than those low-income families. From the perspective of consumption price elasticity, consumption in education, culture and housing is elastic in the long run, while the self price elasticity of most types of consumption fail to fluctuate, and all kinds of cross price elasticity have little impact on food consumption in different periods. Moreover, the consumption in healthcare tend to decline under the influence of other types of consumption.
