城镇化水平及其对城乡收入差距的影响研究

Analysis of Urbanization Level and Its Effect on Urban-rural Income Gap

城镇化进程对我国城乡收入差距的影响具有非线性和阶段性,为了检验这种理论预期,运用我国2000-2012年省级门限面板模型进行实证研究。研究表明:城镇化水平对城乡收入差距存在非线性效应。当城镇化水平低于34.77%时,城镇化的推进有助于城乡收入差距的缩小;介于34.77%和53.49%之间时,城镇化水平对城乡收入差距的收敛程度有所降低;而超过53.49%水平,城镇化的推进则不利于城乡收入差距的缩小。而此时城镇化的推进需要注重城镇化质量、完善城镇化健康发展体制机制、推进城乡户籍制度以及城乡二元土地制度的改革,以此逐步缩小城乡收入差距。

Urbanization has nonlinear and periodic effect on urban-rural income gap. To testify the prospect of this theory, an empirical study is conducted to analyze the provincial data from 2000 to 2012 in a way of panel threshold model. It shows that the level of urbanization on urban-rural income gap has a significant nonlinear effect. When the level of urbanization is lower than 34.77%, the urbanization role is significant, and while between 34.77% and 53.49%, the urbanization role is weakened. But when it exceeds 53.49%, urbanization is not conducive to narrowing the income gap between urban and rural areas. Meanwhile, it needs to pay attention to the quality of urbanization, to improve the healthy development of the mechanism of urbanization, and to promote reform of household registration and land system so that the income gap between urban and rural areas can be narrowed gradually.
