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Lud-vigson（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.
