摘要
近年来中国城市化水平不断向前推进,技术进步程度日益提高,然而城乡收入差距却居高不下。为了深入分析这三者间的动态关系,基于向量自回归(VAR)模型,利用Granger因果检验和脉冲响应函数,对中国1985～2009年城市化、技术进步与城乡收入差距的关系进行动态分析。结果表明:城市化和技术进步是影响城乡收入差距的原因,对城乡收入差距的长期冲击效应均为正;城市化是推动技术进步发展的原因,反之,技术进步对城市化的影响效果并不显著。
In recent years Chinese urbanization level prompted forward unceasingly, the technology advancement degree enhanced day by day, however the urban - rural income gap actually stayed at a high level. To analyze these three thor- oughly the dynamic relation, this paper empirically researches into urbanization, technology advancement and urban - rural income gap by a VAR model, granger causality test and impulse response function in China in the period from 1985 to 2009. Results show that technology advancement and urbanization are the causes to urban - rural income gap, and the long impact responses are positive; urbanization propel the technology advancement forward, otherwise, technological advance- ment has no significant effect on urbanization.
