高水平保护和高质量发展视域下区域水资源脱钩路径研究OACHSSCD

"Decoupling of water resources"is a new situation that has emerged in the high-level promotion of water governance in China.It is a new issue that needs to be deeply studied in order to coordinate high-quality development and high-level protection in China after"the water reaches its peak".Based on systems theory,it studies the decoupling mechanism of water resources from the perspectives of high-level protection of water resources and high-quality economic development.By constructing a research route of decomposition,induction,synthesis and analysis,a comparable input-output model for water resources in 30 provinces is constructed.Structural Decomposition Analysis(SDA)is used to decompose the factors driving water resource decoupling,and from the perspectives of high-level protection and high-quality development,induction and synthesis are carried out to obtain the decoupling force values contributed by each factor in three time periods of each province.It is found that there are significant differences in decoupling force at different time periods in China.The evolution of China's decoupling force exhibits stage-specific characteristics:from 2007 to 2012,it transitioned from a path driven by technological progress to one driven by improvements in development quality,while from 2012 to 2017 and from 2017 to 2022,it evolved into a dual-wheel drive pattern driven by practical water-saving technologies and enhancements in development quality.Ensuring national food security is an important factor contributing to the differences in water decoupling paths.Provinces with higher development quality have relatively unique paths of water decoupling.The actual progress of water-saving technology is playing the role of a"ballast stone"for water decoupling.
