摘　　要：代际流动性是衡量一个社会机会公平程度的重要指标,食品消费和收入的代际弹性分别从基本经济福利和整体经济禀赋两个方面对此进行反映。本文采用中国健康与营养调查数据,首次对中国食品消费的代际弹性进行了估计,并在同一数据库内将其与收入进行了比较。我们发现,与收入的代际弹性(0.427)相比,食品消费的代际弹性(0.879)更高,且在采用多年均值时更为稳定;同时,城镇户籍人口和受教育程度较高者拥有显著更高的代际收入流动性,而食品消费弹性在不同人群中的差异较小,显示基本经济福利和整体经济禀赋的代际不平等情况可能并不完全一致。Intergenerational persistence reflects the degree of inequality in opportunity in a society. Intergenerational income mobility and food consumption mobility reflects this inequality respectively from the aspect of overall economic power and basic economic welfare. Using the Chinese Health and Nutrition Survey, this essay evaluates the intergenerational food consumption persistence and income persistence in China. We find that intergenerational food consumption elasticity is larger than intergenerational income elasticity, and it is more stable when using averaged values. We also find that those who have urban hukou or a higher education level have significantly higher intergenerational income elasticity. Different groups of people have no significant difference in food consumption elasticity. This suggests that the intergenerational inequality of overall economic power and basic economic welfare in China may differ.
