随着改革开放的发展,我国国内居民消费水平与国际贸易水平都得到了很大提高.为了研究国内居民消费与进口贸易的真实关系,本文将消费需求和消费结构作为进口贸易的解释性指标,对这三项指标1978-2011年的时间序列数据进行了变量平稳性检验、协整检验、Granger因果检验,并利用VAR模型、脉冲响应函数分析得出:消费需求、消费结构与进口贸易之间具有动态关系,消费需求对进口贸易具有正向冲击,冲击效果由弱变强;消费结构对进口冲击具有负向冲击,冲击效果有由强转弱的趋势,两者的持续时间较长.在此基础上提出了提高消费需求、优化消费结构和促进进口贸易增长的政策建议.“,”The levels of national consumption and international trade have improved with the development of reform and opening up. This article puts consumer demands and consumption structures as the explanatory indicators of import trade,in order to study on the relationship between domestic consumption and imports. It conducts some experiments of variable stationarity,cointegration and causality to the three indexes time series data from 1978 to 2011,then it got the dynamic relationship among consumer demands,consumption structures and import trade by VAR model and impulse response function. The impact effect of consumer demands and consumption structures to import trade are obvious and long. On this basis,the article puts forward policy suggestions about improving consumer demands,consumption structures and import trade depending on these experiments.
