基于AIDS模型的中国城乡消费偏好差异分析

Analysis of Chinese Urban and Rural Differences in Consumer Preferences Based on AIDS Model

城乡二元市场分割来自于城乡购买力不平衡与城乡消费偏好差异,而城乡消费偏好差异反映在城乡消费结构变迁中。本文通过一个反映城乡消费结构差异的AIDS模型对中国2004—2010年的八类商品消费的省际面板数据进行了实证分析,并进一步计算城乡居民消费的支出弹性、价格弹性和边际消费份额。研究结果表明,除食品类消费均体现为"必需品"特征外,城乡其他消费品类均存在性质上的差异,城市居民更偏好"享受型"消费而农村居民更加偏好"安全型"消费。要建立统筹城乡的商贸流通体系,应通过提高农民收入和推进基本公共服务均等化来缩小城乡消费水平和消费结构差异。

Market segmentation from the urban and rural purchasing power imbalance in urban and rural differences in urban and rural consumer preferences, and urban-rural differences in consumer preferences are reflected in changes in consumption structure of urban and rural areas. In this paper, a reflection of the consumption structure of urban-rural differences in China＇s AIDS model of the eight categories of goods 2004- 2010 provincial consumer panel data empirical analysis, and further calculate the elasticity of urban and rural household consumption expenditure, consumer price elasticity and marginal share. The results show that, in addition to food consumption are reflected as ＂necessities＂ feature, the urban and rural consumer goods are there other differences in the nature of urban residents prefer the ＂enjoyment＂ Consumer preferences for rural residents more ＂safe＂ consumption. To establish urban and rural commerce and distribution, should be adopted to improve farmers＇ income and promote the equalization of basic public services to reduce the consumption level and consumption structure of urban and rural differences.
