Taking 57 prefecture-level cities in the Yellow River basin as a research area, this study evaluates the coupling coordination level of the water–energy–carbon (WEC) system in the Yellow River basin from 2012 to 2021 and explores the driving factors of coupling coordinated development. The study revealed that: (1) the development level of the three subsystems all showed an upward trend. The development level of the carbon system exhibited the highest level. The development index of the carbon and energy systems rose steadily, whereas the development index of the water system fluctuated considerably during the research period, although the magnitude of the fluctuation gradually slowed down. (2) The coupling coordination degree displayed a distribution characteristic of “high in the east and low in the west, high in the south and low in the north”. While the coupling coordination degree improved year by year, the spatial heterogeneity gradually increased. (3) The coupling coordination degree presented a positive correlation, and the agglomeration level was dominated by “high-high” and “low-low” agglomeration types. The “high-high” agglomeration area had a certain degree of spatial mobility, while the “low-low” agglomeration areas showed a tendency for spreading towards the middle reaches of the Yellow River basin. (4) Technological innovation, and the economic basis, had a significant positive impact on the coupling coordinated development, while the industrial structure bias showed a clear inhibitory effect. The positive role of opening up is not yet significant. Meanwhile, the indirect effect of each driving factor was greater than the direct effect.

“…It can be measured in terms of energy consumption per unit of output, or as a percentage of the total energy used in production. 31,32 Additionally, the energy efficiency can be an important tool for improving the sustainability and efficiency of the water-energy-food nexus. 32 Improved energy efficiency can reduce the amount of energy needed to produce a product or service, which can reduce production costs and reduce greenhouse gas emissions associated with energy production.…”

“…It is also important to consider the source of energy used in production, and to promote the use of renewable and clean energies. 31 In addition to reducing production costs and greenhouse gas emissions, greater energy efficiency can also improve the competitiveness of products and services in the marketplace. Consumers are increasingly aware of the importance of sustainability and energy efficiency, and adopting more efficient production practices can be a competitive advantage for companies.…”
