我国城镇居民不同收入群体的消费需求分析

An Analysis of Consumption Demand of Urban Residents by Different Income Groups

本文对我国城镇居民不同收入组的消费结构进行了分析,同时利用恩格尔扩展模型建立消费需求函数,对各项消费品的需求支出弹性进行测算。研究结果表明,不同收入群体的城镇居民消费需求存在明显差异,对食品等生存型的消费品支出弹性随收入增加依次递减,对改善生活和发展类的消费品呈递增趋势。由此,在关注消费结构升级的基础上,制定产业政策需要更多关注重点收入组群的消费需求。

To accelerate the economic transformation of China＇s consumption upgrade is one of the important issue of ＂the 13th Five-Year Plan. Using Engel model and its extension to establish consumer demand function, this paper empirically analyzes consumption structure of Chinese urban residents divided into different income groups, and calculate different goods＇ expenditure elasticity. The results show that there are significant difference in consumption demand of residents divided into different income groups. And expenditure elasticity for subsistence will decrease with the increasing of income, while expenditure elasticity for durable goods will increase at the same time. Thus, on the basis of concerning upgrading of consumption structure, when formulating industrial policy, we should pay more attention to consumption demand of some important income groups
