针对大多数研究文献往往忽视区域间的空间相关性,容易导致研究结论缺乏解释力的事实,本文采用较为前沿的空间计量方法研究我国29个省区1991—2008年间城乡收入差距与全要素生产率之间的关系。研究结果表明:(1)我国各省份城乡收入差距表现出明显的空间集群特征,绝大部分省区属于高-高和低-低类型;(2)全要素生产率的提高扩大了城乡收入差距;(3)人力资本、外商直接投资、对外贸易程度、城镇化水平在一定程度上扩大了城乡收入差距;(4)就业人员比重对城乡收入差距的扩大起到了一定的抑制作用。
Based on China's panel data of 29 provinces during 1991-2008, this paper employs spatial econometrics to study the relationship between income disparity of urban and rural areas and the TFP. Our estimation result shows : ( 1 ) Income disparity of urban and rural areas shows a distinct spatial dependence, and most prov- inces locate at high-high and low-low regions. (2) The improvement of TFP increases income disparity of urban and rural areas. (3) The human capital, FDI, trade and the level of urbanization widens the income disparity of urban and rural areas in some degree. (4) The ratio of employment reduces income disparity of urban and rural areas in some degree.
