Space-time Evolution and Shortcomings on the Green Transformation Capabilities of Urban Clusters in the Yangtze River Economic Belt
We employed the four primary entities driving urban transformation:the government,corporations,industries,and local residents,and established an indicator system to evaluate urban green transformation capabilities.The TOPSIS model was applied to assess the green transformation capability of urban clusters in the Yangtze River Economic Belt(YREB)during the decade from 2010 to 2020.With the application of tools such as regional imbalance indices,dynamic change indices,and exploratory spatial data analysis,we recognized space-time evolutions,patterns of cluster and potential shortcomings within the green transformation capabilities of various urban clusters in the YREB.The results indicated that:(1)For the studied period,the green transformation capabilities of urban clusters in the YREB exhibited a general stable growth.On average,the capability hierarchy was"Yangtze River Delta＞Central Guizhou＞Middle Reaches of Yangtze River＞Chengdu-Chongqing＞Central Yunnan Urban Cluster".The regional imbalance index demonstrated the"N"shaped oscillation,following a"growth-decline-growth"trajectory.The overall level of dynamic changes remained relatively low,with cities exhibiting higher dynamic change indices predominantly positioned within the central and western urban clusters.There was noticeable spatial clustering of urban green transformation capabilities,although this phenomenon showed a slight reduction in 2020.(2)The business-industry axis was the principal shortcoming in all urban clusters'green transformation capability.The green transformation capability of businesses was the foremost shortcoming across all urban clusters,with the green transformation capability of industries being the secondary shortcoming in the Middle Reaches of Yangtze River,Chengdu-Chongqing,Central Guizhou,and Central Yunnan Urban Cluster.Simultaneously,the influence of the government and residents'green transformation capabilities on the overall performance of the Yangtze River Delta Urban Cluster had been progressively enhanced.
