In order to provide reference for the institutional construction of ecological protection and high-quality development in the Yellow River Basin, from a methodological perspective, this paper analyzed the new institutional construction needs for ecological protection and high-quality development in the Yellow River Basin, and the contradiction of the overall requirements of basin governance between fragmented management in reality. On the premise of adhering to ecological priority and green development, and implementing tailored and classified policies, the above issues could be solved by finding the smallest tool unit that covered both ecological protection and high-quality development. Green credit is the minimum common multiple between ecological protection and high-quality development. Establishing a green credit system through laws, regulations and policy regulations is a necessary foundation and logical starting point for basin collaborative governance. Yellow River Conservancy Commission and the nine provinces (regions) in the Yellow River Basin can, in accordance with higher-level laws and relevant policies such as the Yellow River Protection Law, promptly introduce operational norms applicable to the basin and region.

In order to explore an effective way to improve the coupling and coordination between ecological protection and high-quality development in the Yellow River Basin, build a high-quality development evaluation index system including five dimensions of innovative development, coordinated development, green development, open development and shared development, and an ecological evaluation index system including three dimensions of ecological environment resources, ecological environment carrying capacity and ecological environment management and based on panel data from nine provinces (regions) in the Yellow River Basin from 2002 to 2021, the entropy-weighted TOPSIS method was used to calculate the high-quality development index and ecological protection index. Then it calculated the coupling coordination degree and the decoupling index of the two and analyzed the coupling coordination level, decoupling state and its temporal and spatial changes. The results show that a) from 2002 to 2021, the level of ecological protection and high-quality development in the Yellow River Basin has been improved and the trend of change is steadily improving. However, the issues of uneven high-quality development in the western region lagging behind the eastern region, the larger differences in ecological protection among the provinces (regions) and the fragile ecological environment have not been fundamentally changed. b) The coupling coordination degree between ecological protection and high-quality development in the Yellow River Basin fluctuated significantly before 2010 and the coupling coordination level was basically imbalanced. After 2010, the coupling coordination degree has been steadily improved, and the coupling coordination level is gradually shifted from primary coordination to good coordination and high-quality coordination. However, there are significant differences in the coupling coordination degree and coupling coordination level among different provinces (regions) . c) The decoupling state between ecological protection and high-quality development in the nine provinces (regions) of the Yellow River Basin from 2002 to 2021, in a few years, it is an expansion connection or weak decoupling, and most years experiencing unsatisfactory strong decoupling, strong negative decoupling, weak negative decoupling or declining coupling. At the end of the research period, most provinces (regions) experience a decline in high-quality development level accompanied by a strong negative decoupling state of improved ecological environment. This paper puts forward the path to enhance the coupling coordination between ecological environment protection and high-quality development of strengthening the flow of industrial development factors, accelerating industrial transformation and upgrading, and promoting the development of digital economy.

In order to provide reference for the formulation of relevant policies for the ecological protection and high-quality development of the Yellow River Basin, this paper started from the perspective of the dual coupling of ecological protection and high-quality development in the Yellow River Basin to build separate evaluation indicator systems for development quality and ecological protection. Then, it calculated the development quality index and ecological protection index of each province (autonomous region) in the year 2020 by using entropy method. It built a two-dimensional quadrant model of ecological protection and development quality with the national average development quality index and ecological protection index as the coordinate origin. Based on the distribution of each province (autonomous region) in the two-dimensional quadrants, it determined the coordination status of ecological protection and high-quality development. The results show that there is significant variation in ecological protection and development quality among provinces (autonomous regions) in the Yellow River Basin, with prominent issues of imbalance and inadequacy. Using the national average development quality index and ecological protection index as benchmarks, considering a development quality index higher than the national average as high quality and an ecological protection index higher than the national average as good ecological quality, the coordination status of ecological protection and high-quality development in the various provinces (autonomous regions) of the Yellow River Basin is classified into four types of excellent ecology-high quality, excellent ecology-low quality, low ecology-low quality and low ecology-high quality. The results show that only Sichuan is in a relatively ideal state of excellent ecology-high quality, while the other provinces (autonomous regions) are in the three types of non-coordinated states of excellent ecology-low quality, low ecology-low quality and low ecology-high quality. Finally, it proposes the establishment of a long-term mechanism for the coordinated advancement of ecological protection and high-quality development in the Yellow River Basin, focusing on the six aspects of top-level strategic design, inter-provincial (autonomous regional) collaborative control, public participation, rigid constraints on ecological protection, constraints on rights, responsibilities and interests and ecological compensation.

Scientific and technological innovation is the fundamental support for ecological protection and high-quality development in the Yellow River Basin. This paper analyzed the current status of scientific and technological innovation in nine provinces ( autonomous regions) in the Yellow River Basin from 2016 to 2020, and finds that the supporting mechanisms of scientific and technological innovation for ecological protection and high-quality development in the Yellow River Basin are as follows: speed up the digitalization process of factors of production, smooth the high-quality factor circulation mechanism, improve the adaptability and innovation level of the economic structure, build high-quality synergy mechanism, optimize the law-based business environment, and implement the digitalization progressive governance mechanism. The Yellow River Basin ecological protection and high quality development of science and technology innovation support mechanism path and policy Suggestions for: in green technology innovation as the gripper coordinated development, promote the global ecological construction of the Yellow River Basin integrated large data center, improve the efficiency of digital integration of government affairs, increase efficiency and improve the business environment under the rule of law governance service governance and supervision system, etc. [ABSTRACT FROM AUTHOR]

In order to deepen the research on the coordination mechanism of ecological protection and economic development of the urban agglomerations in the Yellow River Basin, and to provide references for the research on high-quality development in the Yellow River Basin, taking the Lanzhou-Xi' an urban agglomeration, the Guanzhong Plain urban agglomeration, the Shandong Peninsula urban agglomeration, and the Huhhot-Baotou-Erdos-Yulin urban agglomeration, Central China urban agglomeration, Central Shanxi urban agglomeration, and Ningxia urban agglomeration along the Yellow River as the research objects, this paper established an index system according to the four subsystems of ecological environment, economic development, human water relationship, and people' s happiness . It adopted the entropy weight method and the coefficient of variation method to determine the index weights and SMI-P model to calculate the coordination degree between ecologic; J protection and high-quality development, and analyzed the changes in the coordination degree between ecological protection and high-quality development in urban agglomerations along the Yellow River from 2009 to 2018. The results show that the coordination degree of ecological protection and high-quality development of the urban agglomerations along the Yellow River presents a cascade distribution pattern of high in the cast and low in the west (high in the downstream and low in the upper reaches) ; the degree of coordination between protection and high-quality development is rising, and the difference in the degree of coordination among urban agglomerations is gradually decreasing; in 2009, only the Shandong Peninsula urban agglomeration is in a state of 'close to synergy", while most other urban agglomerations arc in a state of "on the verge of imbalance" ; in 2018, the Central China urban agglomeration and the Huhhot-Baotou-Erdos -Yulin urban agglomeration also reach a state of "close to synergy", while other urban agglomerations are about to reach a state of "close to synergy" ; there arc: significant spatial differences of the coordinated development index among four subsystems (i.e. ecological environment, economic development, human-water relationship, and people' s happiness of each urban agglomeration) . The urban agglomeration with high degree of coordination has a weaker subsystem coordinated development index, while the urban agglomeration with a low degree of coordination has a larger subsystem coordinated development index. Therefore, each urban agglomeration should he adequate to give full play to their respective location advantages and resource advantages, strengthen their weaknesses, and implement differentiated ecological protection and high-quality economic coordinated development.
