Study on the Evolution of Quaternity Cooperation of Water Resources-Ecology-City-Industry in the Yellow River Basin
In order to investigate the dynamic evolution and regional differences of quaternity cooperation of water resources-ecology-city-in-dustry in the Yellow River Basin,the paper adopted the synergy model,kernel density estimation,Dagum gini coefficient and its decomposi-tion to estimate it based on the data of 76 major prefecture-level cities in the Yellow River Basin from 2016 to 2020.The results show that the number of cities in primary,intermediate and good coordination is 30,33 and 13 respectively.The level of synergy among cities is on the rise,but the absolute difference between cities is expanding and the relative difference is narrowing.except for Hu-Bao-E-Yu urban agglomer-ation,the absolute difference of the coordination degree of the other six urban agglomerations all shows an expanding trend.The internal differences between the upper and lower reaches of the Yellow River show a downward trend,while the internal differences in the middle rea-ches show an upward trend.The difference between the upper and middle reaches is the largest,and it shows a further expansion trend,and the difference between the upper and lower reaches is gradually narrowing.The difference in Hu-Bao-E-Yu urban agglomeration is the smal-lest and the difference in Guanzhong urban agglomeration is the largest.The difference between Guanzhong urban agglomeration and Shandong peninsula urban agglomeration is the smallest,and the difference between Jinzhong urban agglomeration and Shandong peninsula urban ag-glomeration is the largest.In the future,we should further strengthen factor coordination and regional coordination,give play to the dynamic comparative advantages of various regions,and promote the in-depth implementation of ecological protection and high-quality development strategies according to local conditions in the Yellow River Basin.
