【摘要】：在食品通胀周期背景下,使用城镇住户抽样调查数据及AIDS-ECM模型对城镇居民食品消费结构动态及福利损失进行了研究。研究结果表明:首先,长期中分类食品价格上涨会增加自身消费支出,而抑制其它分类食品消费支出。短期中通过食品消费结构调整实现动态均衡,且收入层次越高调整速度越显著,食品结构越均衡;其次,长短期中食品质量越高其支出弹性越高,且高质量食品支出弹性随收入层次增加而增加。短期自价格弹性较长期弹性敏感,高质量食品自价格弹性在中、高收入层才显著;再次,城镇居民食品消费的福利具有周期性特征,粮食、肉禽类食品消费福利构成食品消费福利主体,通胀期的福利损失大于收缩期的福利获得,在长短期中食品消费福利变化随收入层次增加而减少。现阶段稳定核心食品价格,减小收入分层差距,是优化城镇居民食品消费结构,增加福利的两个重要途径。
[Abstract]:Under the background of food inflation cycle, the dynamics of food consumption structure and welfare loss of urban residents were studied by using sample survey data of urban households and AIDS-ECM model. The results show that: first, the increase in the price of classified food in the long run will increase their own consumption expenditure, while restrain the other categories of food consumption expenditure. In the short term, the food consumption structure is dynamically balanced through the adjustment of food consumption structure, and the higher the income level is, the more significant the adjustment speed is, the more balanced the food structure is; Secondly, the higher the food quality in the long and short term, the higher the expenditure elasticity, and the higher the expenditure elasticity of high quality food is with the increase of income level. Short-term self-price elasticity is more sensitive than long-term elasticity, high quality food self-price elasticity is in the middle, high income level is significant; Thirdly, the welfare of food consumption of urban residents has cyclical characteristics. Food, meat and poultry food consumption welfare constitutes the main body of food consumption welfare, and the welfare loss in inflation period is greater than that in contraction period. In the long-term and short-term, the change of food consumption welfare decreases with the increase of income level. At present, stabilizing the core food price and reducing the income stratification gap are two important ways to optimize the food consumption structure and increase the welfare of urban residents.
