摘要
在推进高质量发展的关键时期,产业结构与土地利用效率的耦合协调发展对科学化城市管理和城市发展具有重要意义。该研究以长江经济带沿线108个地级及以上城市为研究对象,在测算2006—2018年产业结构合理化(Industrial Structure Rationalization,ISR)、产业结构高级化水平(Industrial Structure Advanced level,ISA)以及城市土地利用效率(Land Use Efficiency,LUE)的基础上,采用耦合协调度模型及空间自相关模型分析城市产业结构与土地利用效率耦合协调性的时空格局及空间关联特征。结果表明:1)产业结构合理化与土地利用效率的耦合协调度(DRE)整体处于勉强协调阶段且随时间协调度呈现上升态势;产业结构高级化水平与土地利用效率协调性(DAE)处于勉强协调向初级协调转变阶段。2)DRE和DAE整体上都呈现“下游、中游、上游”的空间分布格局,区域之间的协调度差异随时间推移有所减小。3)全局自相关结果表明:DRE和DAE存在着显著的空间自相关性,其中DRE的空间自相关性随时间逐渐减弱,而DAE则变化不明显。局部空间自相关结果表明:DRE的HH类型区主要在苏浙皖交界区域小范围集聚,L-L集聚区主要分布在长江上游四川东部、贵州西部及云南西南部的部分城市,L-H聚集区零星分布长江中下游各区域的交界地区,H-L聚集区几乎不出现;DAE的H-H集聚区主要分布在江苏和浙江境内,L-L集聚区零星分布在上游地区、安徽北部及期与江西交界地区,L-H聚集区分布在江苏淮安、浙江舟山和安徽宣城市,H-L聚集区个别年份出现个别城市。研究认为,要针对产业结构与土地利用效率中低耦合协调度匹配类型,从解决“低水平陷阱”入手,实施差异化的土地与产业调控政策;除此之外,也要充分考虑产业结构合理化、产业结构高级化与土地利用效率联动发展的空间关联性,因地制宜的实施发展策略。
Coupling and coordination between industrial structure and land-use efficiency have been one of the most important strategies for urban management in the critical period of high quality,comprehensive and sustainable development.Taking 108 prefecture-level and above cities along the Yangtze River Economic Belt as the study area,this study aims to investigate the spatio-temporal pattern of the coordination degree between urban industrial structure and land-use efficiency.A coupling coordination degree model was employed to calculate the Industrial Structure Rationalization(ISR),Industrial Structure Advanced level(ISA),and urban Land Use Efficiency(LUE)from 2006 to 2018.A spatial autocorrelation model was further used to analyze the spatial correlation of the coupling and coordination between urban industrial structure and land-use efficiency.The results indicated that:1)The coupling and coordination degree between industrial structure rationalization and land-use efficiency(DRE)was in a barely coordinated stage as a whole,where the degree of DRE showed an upward trend.Meanwhile,the coupling and coordination degree between industrial structure advancement and land-use efficiency was in the transition stage from the barely to primary coordination,where the degree of DAE was on the rise.2)In terms of spatial pattern,both DRE and DAE presented a distribution pattern of"downstream>midstream>upstream",as time went by.There was also a decreasing difference in the coordination degree of the industrial structure and land-use efficiency over the regions.3)The global autocorrelation showed that the DRE and DAE presented a significant spatial autocorrelation.Specifically,the spatial autocorrelation of DRE became weaker over the time,whereas,there was only a little change of DAE.The local spatial autocorrelation showed that:the H-H type areas of DRE were mainly concentrated in a small area at the junction of Jiangsu,Zhejiang and Anhui,whereas,the L-L agglomeration areas were mainly distributed in some cities in the upper reaches of the Yangtze River,including the eastern Sichuan Province,western Guizhou Province and southwestern Yunnan Province,while,the L-H agglomeration areas were scattered in the border areas of the middle and lower reaches of the Yangtze River,the HL agglomeration areas were almost non-existent,the H-H agglomeration areas of DAE were mainly distributed in Jiangsu and Zhejiang provinces,the L-L agglomeration areas were scattered in the upper reaches,such as the northern Anhui Province and the junction of Anhui and Jiangxi,the L-H agglomeration areas were located in the Huai'an City of Jiangsu Province,Zhoushan City of Zhejiang Province,and Xuancheng city of Anhui Province,the HL agglomeration areas were just appeared in the individual provinces in some years.Consequently,some recommendation was made that the“low-level trap”needed to be bridged for the decision making on the differentiated land and industrial control,according to the matching type of industrial structure-land use efficiency-medium-low coupling coordination degree.Furthermore,it is necessary to fully consider the spatial correlation between the proper,advanced industrial structure and the land-use efficiency,when implementing the development strategies,according to the local conditions.
