新型城镇化对缩小城乡收入差距的作用——基于城乡二元收入的理论模型与实证检验

Effect of New Urbanization on Narrowing Urban-Rural Income Gap: Based on the Theoretical Model of Urban-Rural Income and Empirical Test

基于城乡二元收入模型理论分析与实证检验了新型城镇化对城乡收入差距的作用机制。研究结果表明:若新型城镇化战略的实施不打折扣,则无论是在刘易斯的劳动力"无限供给"阶段,还是在劳动力"有限剩余"阶段,新型城镇化始终会缩小城乡收入差距;利用我国2000—2011年省际面板数据对新型城镇化与城乡收入差距之间的作用机制进行了实证检验,检验结果显示新型城镇化对缩小城乡收入差距的作用显著,同时新型城镇化也受到城乡收入差距缩小带来的良性反馈作用。因此积极稳妥地推进新型城镇化,是缩小我国城乡收入差距的有效途径。

In this paper, the authors make a theoretical analysis and empirical test for mechanism of new urbanization and urban-rural income gap based on the urban-rural income model. The results show that new urbanization will always narrow the income gap between urban and rural areas; if the implementation of new urbanization strategy is uncompromised, regardless of the labor force in the Lewis “unlimited supply” stage, or in“limited supply” stage, Then, this mechanism has been tested by using 2000-2011 inter-provincial panel data. The empirical results show that the new urbanization has significant effect on narrowing the urban-rural income gap, while new urbanization receives positive feedback. Therefore, that China pushes forward the new urbanization actively and steadily is an effective way to narrow the urban-rural income gap.
