摘要
本文采用熵值法和耦合协调度模型,对我国30个省市区在2007-2017年区间的城乡融合水平进行了测度,并通过Kernel密度估计和Dagum基尼系数分解方法,分析我国城乡融合水平的绝对差异和相对差异,最后使用σ-收敛模型、绝对β-收敛模型和条件β-收敛模型检验城乡融合水平的收敛性特征。结果表明,我国城乡融合水平总体呈现逐年提高的趋势,但是提升的速度开始放缓,并且区域之间存在差异。进一步研究发现,我国城乡融合水平差异在全国层面经历了先扩大后缩小的过程,但是东部地区分化加大,西部地区处在不断缩小之中,中部地区差异最小,城乡融合水平的差异主要是由地区间的差异贡献的。从σ-收敛性来看,东部地区变异系数不断波动,缺乏σ-收敛,中部地区城乡融合水平变异系数有上升趋势,没有σ-收敛,西部地区存在σ-收敛。从β-收敛性来看,全国和地区层面都存在显著的β-收敛,不管是绝对β-收敛还是条件β-收敛,收敛的速度都是"中部>东部>西部",说明西部地区的城乡融合水平在追赶东部和中部地区,而中部和东部的差异越来越大。
This paper uses entropy method and coupling coordination model to evaluate the urban-rural integration level of 30 provinces in 2007-2017.Then,the absolute and relative differences of urban-rural integration level are analyzed by Kernel density estimation and Dagum Gini coefficient decomposition method.Finally,σ-convergence model,absoluteβ-convergence model and conditionalβ-convergence model are used to test the convergence characteristics of urban-rural integration level.The results show that the overall level of urban-rural integration in China shows a trend of increasing year by year,but the speed of improvement has begun to slow down.Further research shows that the overall difference of urban-rural integration level in China has experienced the process of expansion first and then reduction,in which the differentiation in the eastern region has increased,the western region is in the process of continuous reduction,and the difference in the central region is the smallest.The difference of urban-rural integration level is mainly contributed by the difference between regions.In terms ofσ-convergence,the coefficient of variation in the eastern region fluctuates continuously and lacks ofσ-convergence.In the central region,the coefficient of variation tends to rise withoutσ-convergence.In the western region,there isσ-convergence.From the perspective ofβ-convergence,there are significant absoluteβ-convergence and conditionalβ-convergence at the national and regional levels,and the convergence speed is"Central>Eastern>Western",indicating that the level of urban-rural integration in the western region is catching up with the eastern and central regions,while the difference between the central and eastern regions is growing.
