摘要: 以中国12个城市群(圈)为研究对象,采用随机森林算法及空间计量模型实证检验区域一体化对城市土地利用效率的空间驱动效应。研究表明:时间维度上,2013—2019年我国12个城市群(圈)区域一体化和城市土地利用效率水平均呈现出波动上升趋势,且在空间维度上表现出自东向西走向的“递减式”空间演化规律;整体而言,区域一体化对城市土地利用效率提升具有显著直接影响及溢出效应。分区域而言,区域一体化提升城市土地利用效率的直接作用,呈现出自东向西愈来愈强的现实特征,但其空间溢出效应仅在东部凸显。为此,在推动城市土地高效利用的过程中,既要深入实施区域一体化战略来加快土地利用模式转型,又要注重区域之间的空间溢出,探寻区域一体化驱动城市土地利用效率提升的差异性路径。

Abstract: 12 urban agglomerations in China were taken as the research object, and the random forest algorithm and the spatial econometric model were used to test the spatially driving effect of regional integration on the urban land use efficiency. The results showed that from 2013 to 2019, the level of regional integration and urban land use efficiency of 12 urban agglomerations in China fluctuates and increases in the time dimension, and a “decreasing” spatial evolution from the east to the west is featured in the spatial dimension. On the whole, regional integration has significant direct impact and spillover effect on the improvement of urban land use efficiency. From the regional perspective, the direct role of regional integration in improving urban land use efficiency is becoming stronger and stronger from the east to the west, but its spatial spillover effect is only prominent in the east. Therefore, in the process of promoting the efficient use of urban land, the regional integration strategy to speed up the transformation of land use modes should be implemented in depth, the spatial spillover between regions should be paid attention to, and the differential paths of regional integration to promote urban land use efficiency should be explored.

Key words: regional integration; urban land use efficiency; driving mechanism; spatial effect
