促进城镇化与经济、社会、资源环境的相互协调是高质量城镇化的基本要求.选取多维度核心指标,基于城镇化动态演变理念,通过时间序列分析,构建城镇化—经济、城镇化—社会、城镇化—资源和城镇化—环境协调度指数,以县域为单元探究了青藏高原城镇化多维协调时空演变过程及其影响机制.研究发现,青藏高原城镇化—资源协调水平最高,但呈总体下降趋势;城镇化—经济和城镇化—社会协调水平较低,呈上升趋势;城镇化—环境协调水平居中且基本稳定.青海和甘南总协调度下降,城镇化发展速度超过经济发展速度,并对资源环境形成压力.西藏、川西和滇西总协调度上升,城镇化发展的经济基础不断夯实的同时,城镇化略显滞后.回归结果表明,城镇化—经济协调度主要受到产业结构的影响,工业化是改善城镇化—经济协调度的关键因素;城镇化—社会协调度主要受政府财政能力的影响,财政支出规模越大,协调度越高;城镇化—资源和环境协调度受到经济发展和政府财政支出的共同负向影响,即工业比重越高,政府财政支出能力越强,城镇化—资源和环境协调度越低,显示青藏高原经济发展与环境保护的两难.但是县域规模以上工业企业数量越多,中心城镇集聚规模越大,则城镇化—资源环境协调度越高,为青藏高原选择适宜的城镇化和工业化模式提供了启示.
Fostering coordination among the economy,society,resources and environment is a crucial requirement for high-quality urbanization.This work developed an indicator system for the degree of coordination involving urbanization-economy,urbanization-society,urbanization-resources and urbanization-environment based on the dynamic evolution of urbanization and time series analysis.Using counties as the statistical unit,the study investigated the spatiotemporal evolution process and impact mechanism of the multidimensional coordinated urbanization from 2000 to 2020 on the Qinghai-Tibet Plateau.Urbanization-resource coordination was found to be the highest overall.The levels of coordination between urbanization-economy and urbanization-society were relatively low,whereas the coordination degree for urbanization-environment was moderate and essentially consistent.The measurements described above showed a convergent tendency between 2000 and 2020.The levels of coordination between Qinghai and southern Gansu generally decreased,and the rate of urbanization outpaced that of economic growth,placing significant strain on the environment and resources.The overall degree of coordination improved in Xizang,western Sichuan,and Yunnan,despite the fact that their individual coordination levels were on the decline.The regression findings showed that the industrial development,which is primarily influenced by the industrial structure,is a crucial element in enhancing the degree of urbanization-economy coordination.The financial capacity of the government has a significant impact on the degree to which urbanization and society are coordinated.As the scale of fiscal spending expands,it correspondingly rises the degree of coordination.Furthermore,economic development and government fiscal spending have a negative effect on the coordination degree of urbanization-resources and urbanization-environment.When industrial proportion and government fiscal spending capacity increase,the coordination degree of urbanization-resources and urbanization-environment declines,indicating the plateau's dilemma between economic development and environmental protection.However,if the industrial enterprises are primarily larger than the designated size and the scale of the center town agglomeration is enormous,it is conducive to strengthen the coordination degree of urbanization-resources and urbanization-environment.
