城市高质量发展的水平测度与时空演变OA北大核心CHSSCDCSSCICSTPCD

Based on the Five Development Concepts,this paper grasps the connotation of high-quality development and con-structs a high-quality urban development evaluation index system including input,expected output and unexpected output,uses the super-efficiency SBM model to measure the high-quality development level of 211 prefecture-level cities in China from 2011 to 2021,and analyzes the spatial-temporal evolution trend.Then,both the Dagum Gini coefficient method and kernel density esti-mation method are used to study and judge the unbalanced distribution characteristics of the high-quality development level of the city as a whole,each region and the six major urban agglomerations.The results go as the following:The high-quality urban devel-opment level presents the distribution characteristics of"high in the east and west,low in the middle",and the spatial agglomera-tion characteristics are significant.The multi-polar differentiation trend is obvious in the western region,followed by the central region,and the overall coordination degree is the highest in the eastern region.During the study period,the inter-regional differ-ence contribution of high-quality urban development level is smaller than that of intra-regional difference contribution,and the overall Gini coefficient and inter-regional difference contribution show a downward trend,indicating that high-quality urban de-velopment has a trend of transition from unbalanced differentiation to inclusive growth.
