城市化质量的空间特征及其门槛效应研究

通过重构城市化质量评价指标体系,利用熵值法、泰尔指数、变异系数、探索性空间数据分析等方法测度了2007-2016年我国各省市自治区城市化质量的综合水平及其空间特征,基于能源消费结构转型视角构建了面板门槛模型,以检验环境规制对城市化质量的门槛效应。研究显示:我国各省市城市化质量总体上逐步提高,但省域差异呈现出"四降四升"的双W型波动变化趋势。城市化质量省际间存在空间集聚分布格局,但异质性有所增强。冷热点空间格局表现出"东热西冷"的分布规律,环境规制对城市化质量具有显著的双门槛效应,人力资本和经济发展水平对城市化质量具有驱动作用,而能源消耗和收入差距则抑制城市化质量的提升。

Study on the spatial characteristics and threshold effect of urbanization quality

By reconstructing the evaluation index system of urbanization quality,and using Entropy Method,Linear Weighted Sum Method,Thai Index,Coefficient of Variation and Exploratory Spatial Data Analysis,this essay measures the comprehensive level and spatial characteristics of urbanization quality in China’s provinces from 2007 to 2016,and from the perspective of the transformation of energy consumption structure,the Panel Threshold Model is built to test the threshold effect of environmental regulation on urbanization quality.The results show that:The quality of urbanization in China’s provinces has gradually improved,but the inter-provincial differences are increasing with fluctuations as a double-W type;There is a spatial agglomeration distribution pattern among provinces,but the heterogeneity is enhanced;The spatial distribution of its hot pots and cold pots is obvious different;environmental regulation has a significant double threshold effects on urbanization quality;Human capital and level of economic development play a vital role in promoting urbanization quality,Total energy consumption and urban-rural income gap are more effective than suppression of urbanization quality.
