Study on the Measurement of Urban High-Quality Development in the Yellow River Basin Based on the Perspective of"Sansheng"
In view of the fact that the high-quality development of cities has a driving and radiating effect on the high-quality development of the Yellow River Basin,in order to provide reference for the comprehensive implementation of the major national strategy of ecological protec-tion and high-quality development in the Yellow River Basin,the evaluation index system of high-quality development was built from the per-spective of"Sansheng"(ecology,production and life)and the entropy weight TOPSIS method was used to build a high-quality development measurement model.The closeness of high-quality development was used to reflect the high-quality development level,and the high-quality development level of 61 prefecture-level cities in the Yellow River Basin from 2011 to 2020 was measured.K-means clustering algorithm was used to analyze the temporal and spatial variation of high-quality development level of cities in the Yellow River Basin.The results show that a)the level of urban high-quality development in the Yellow River Basin in 2011-2020 shows a significant upward trend.b)At present,the level of high-quality development in the Yellow River Basin is still generally lower.From a spatial point of view,the high-quality development level of cities in the upper and lower reaches is close to and obviously higher than that in the middle reaches.c)There are great differences in the level of high-quality development among cities in the Yellow River Basin.d)Most of the cities with higher level of high-quality develop-ment are provincial capital cities and new first-tier cities,the average water of"Sansheng"is higher,and such cities are less.They are dis-tributed in the upstream areas with better ecological environment and some cities in downstream areas with strong economic development.The level of high-quality development is relatively higher,and one or two of these cities have a higher level of development,which belongs to non-all-round development,and there are few such cities.Other cities that account for a relatively larger proportion have a low level of high-quali-ty development,and the average"Sansheng"water in such cities is relatively lower.It is suggested that a)implement differentiated develop-ment strategies,and cities should adjust measures to local conditions,give full play to their own advantages and make up for the shortcomings of"Sansheng";b)Further improve the competitiveness of central cities,provincial capitals and urban agglomerations,so that they can play a greater role in radiating and driving and;c)Seize the opportunity of development to promote economic development,ecological protection and the improvement of people's livelihood.
