Research on the Triple Coordination of Digital Economy,Green Technology Innovation,and Ecological Protection in the Yellow River Basin
In order to explore the current development status of digital economy,green technology innovation and ecological protection in the Yellow River Basin,as well as the coupling,coordination and interaction relationship among the three,and provide useful reference for the promotion of ecological protection and high-quality development strategies in the Yellow River Basin,on the one hand,to theoretically decon-struct the coupling and coordination mechanism of the three systems of digital economy,green technology innovation and ecological protection in the Yellow River Basin and construct a theoretical framework,on the other hand,taking 77 prefecture level cities in the Yellow River Ba-sin as research units and using 2012-2020 as the research period,this study empirically tested the current status of digital economy,green technology innovation and ecological protection development,and their coupled coordination level in the Yellow River Basin.The results show that a)from 2012 to 2020,the digital economy,green technology innovation and ecological protection index in the Yellow River Basin all show a steady upward trend.The ecological protection index shows a slight fluctuation and stable trend from 2012 to 2019,but shows a signif-icant increase at the end of the research period in 2020.b)The coupling and coordination index of digital economy,green technology innova-tion and ecological protection in the Yellow River Basin has steadily increased during the research period.Through spatial evolution pattern analysis,it can be seen that cities along the basin have all crossed a serious imbalance state during the research period,and cities in a coor-dinated state have also gone through a process from scratch during the research period.Among them,Xi'an,Zhengzhou and Jinan have en-tered into the primary coordination stage.c)From the perspective of the spatial-temporal relationship of coupling coordination,on the one hand,there is a significant positive spatial clustering effect on the coupling coordination degree of digital economy,green technology innova-tion and ecological protection in various cities in the Yellow River Basin.On the other hand,the overall Gini coefficient of the coupling coor-dination degree shows a fluctuating downward trend,and the overall differences in the basin are gradually narrowing.However,specifically,the differences in the coupling coordination development between downstream and upstream regions are gradually expanding.Furthermore,ac-cording to the contribution rate of differences,it can be inferred that the development differences of coupling coordination mainly come from the development differences between watersheds.
