Abstract:At present, the academic research on the development efficiency of the Yellow River Basin is still in the preliminary exploration stage, and there are few studies on the economic and innovation efficiency of the Yellow River Basin and the coupling coordination level of its subsystems. To this end, a three-dimensional analysis framework of "Eco-Economy-Innovation" for high-quality development efficiency of the Yellow River Basin was constructed. Based on the panel data of nine provinces in the Yellow River Basin from 2010 to 2019, the Malmquist index method was used to analyze the evolution trend of high-quality development efficiency in the Yellow River Basin. At the same time, entropy method and coupling coordination model are used to analyze coupling coordination. The results found that: The overall ecological efficiency of the nine provinces and regions showed a declining trend, while the economic efficiency and innovation efficiency showed an increasing trend, and the coupling coordination degree of high-quality development efficiency was at a low level. The overall coupling coordination among ecological, economic and innovation systems is in a slightly maladjusted state. Accordingly, some suggestions are put forward, such as taking corresponding ecological protection measures in different sections of the Yellow River Basin, strengthening market-oriented resource allocation, highlighting the leading role of innovation, and optimizing the linkage and coordination mechanism among provinces.
