极化理论视角下城市建设用地利用效率的时空异质性
Study on spatial-temporal heterogeneity of urban construction land use efficiency from the perspective of polarization theory
摘要
Abstract
The spatial-temporal heterogeneity of urban construction land use efficiency in different scales in China has been widely concerned by theoretical circles,but the study on the measurement of the degree of heterogeneity is rare.Based on the polarization theory from the economics as the research breakthrough point,this paper made the quantitative characterization of the spatial-temporal heterogeneity of urban construction land use efficiency based on the data of 31 provinces in mainland China (municipalities directly under the central government,autonomous regions) in 2001-2014 by employing Data Envelopment Analysis,Kernel density estimation and Esteban-Ray polarization index.The results showed that:①China's urban construction land use efficiency showed falling volatility nationally,and the average efficiency index fluctuated from 0.750 1 in 2001 to 0.694 8 in 2014.The urban land construction utilization efficiency differed obviously among eastern,central and western regions and provincially,the lowest in the western region before 2006,but after 2006 the three major regional urban construction land use efficiency showed geographical pattern of'the eastern region ＞ the west region ＞ the central region'.② China's urban construction land use efficiency gap among regions showed an increasing trend during the study period.The initial value and the stop value of the Kernel density curve of China's urban construction land use efficiency moved to the left firstly,then moving to the right from 2001 to 2014.And compared with 2001,the Kernel density curve of China's urban construction land use efficiency changed significantly and regional difference expanded.③The polarization process of China's urban construction land use efficiency emerged.The Kernel density curve shows unimodal-multimodal-bimodal distribution pattern.Esteban-Ray index,the urban construction land use efficiency of China and three regions was on the rise during the study period;the largest volatility appeared in the central region,increasing from 0.121 9 in 2001 to 0.529 6 in 2014,and the average annual growth rate was 11.96％;the Esteban-Ray index changed stably in the eastern and western regions,increasing from 0.183 0 and 0.162 1 in 2001 to 0.276 2 and 0.216 5 in 2014 respectively,with 3.22％ and 2.25％ the average annual growth rate.关键词
