| description | Jing-Jin-Ji as one of the most serious water shortage areas in China, improving the green efficiency of water resources is the only way to solve the contradiction between supply and demand of water resources and realize the harmonious development of economy, society and ecology. Based on the Super-SBM model and geographical detector model, this paper measures the green water resources efficiency of Jing-Jin-Ji from 2008 to 2018, and analyzes the spatial and temporal differentiation. The result shows that:The efficiency of green water resources in Jing-Jin-Ji fluctuates in an unstable state, and does not reach the DEA effective state, and there is a big gap between the maximum and minimum efficiency of urban agglomeration. |
