摘要
基于1995~2013年省级面板数据,以人均专利授权数衡量创新水平,通过构建工具变量回归模型,从全国和地区两个尺度考察了创新对中国城乡收入差距的影响。结果表明：在全国尺度上,创新对城乡收入差距的影响先缩小后扩大,呈U型关系,拐点值为专利授权数等于5.884件/万人;在地区尺度上,创新对城乡收入差距的影响表现为线性特征。在西部地区,创新对城乡收入差距有缩小作用,在东部地区,则表现为扩大作用。
To explore the impact of innovation on income inequality, this paper used the instrumental variable model to meastare the impact of innovation on urban-rural income gap in China based on panel data from 1995 to 2013. Results showed that, there was a U shape relationship between innovation level and urban-rural income gap, which meant in the short term innovation can decrease the income gap , but it would increase the income gap once the number patents approved per 10,000 people reaches 5. 884 in the long run. In the regional level, there was a linear relationship between innovation and urban-rural income gap. The innovation could increase the income gap in eastern region while it took the inversed effect in western region.
