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.
