基于季度数据的城乡居民消费行为异质性分析

A Study of Heterogeneity of Urban and Rural Residents' Consumption Behaviors

本文基于中国二元结构下城乡居民消费存在差异的现实,对Lettau和Ludvigson(2001)提出的模型进行改进,加入信用卡数量作为自变量,实证检验人均居民收入、股票流通市值、房价指数和信用卡数量对城镇和农村居民消费的影响弹性。结果表明农村居民消费函数的各项弹性均大于城镇居民;信用卡数量影响消费的弹性仅次于收入水平。因此,相关部门应充分认识城镇和农村居民消费行为的差异,重视对农村消费市场的挖掘以刺激消费增长。

Based on the difference between urban and rural residents＇ consumption under China＇s urban-rural dual struc- ture, we improved the model of Lettau-Ludvigson （2001） by adding credit card number as a new independent variable, and tested the respective elasticity of influence on urban and rural residents＇ consumption practice exerted by per capita income, stock market capitalization, house price index and credit card number. We found there is obviously higher elasticity for rural residents than for urban ones, and credit card number affects consumption second only to income. So we recommend that the difference between urban and rural residents＇ consumption behaviors should be fully recognized, the importance of developing rural consumer market should be emphasized, and adequate attention should be paid to changing China＇s consumption ideas and spending habits and promoting the healthy development of the credit card industry in order to stimulate consumption growth.
