城镇化对城乡收入差距影响的区域异质性研究

Research on Regional Heterogeneity of Impact on Urban-rural Income Gap from Urbanization

城镇化是影响我国城乡收入差距的重要因素。本文运用1997—2014年30个省的面板数据，基于门槛模型分别在全国范围及区域层面研究了城镇化对城乡收入差距的影响。研究发现。城镇化对我国城乡收入差距的影响存在显著的门槛效应。进一步运用门槛模型对东部、中部及西部进行分区域分析，回归结果表明：在西部区域，城镇化能够缩小城乡收入差距；而在东部及中部区域，城镇化却恶化了城乡收入差距。认为应该摒弃传统的土地城镇化模式，大力推进以人为核心的新型城镇化建设，因地制宜地在东部、中部及西部分别选择最合适的新型城镇化模式和推进速度，最有效地实现缩小城乡收入差距的政策目标。

Urbanization is an important factor affecting the urban-rural income gap of China. Based on 1997 -2014 pro- vincial panel data, the paper employs threshold-effect model to study the effects of urbanization on the urban-rural income gap at nationwide and regional level respectively. The study shows that there is significant threshold effect on iurben-rural income gap aroused by urbanization. Further, the regression results based on eastern, central and western subregion shows that urbanization can narrow urban-rural income gap in western region but deteriorate the gap in central and western region. The paper gives advice that we should abandon traditional land urbanization mode, vigorously promote the human-centered construction of new urbanization, select the most appropriate model and rate of construction of new urbanization in the eastern, central and western region according to local conditions, narrow the income gap between urban and rural areas to achieve the policy objective effectively.
