patterns, this article employs GRACE satellite data and
statistical records to conduct a comprehensive assessment and
evaluation of water resource utilization efficiency across 34
prefecture-level cities in China's three northeastern
provinces{\textemdash}Liaoning, Jilin, and
Heilongjiang{\textemdash}over the period spanning from 2003 to
2020. By utilizing the sophisticated Super-SBM model, the study
delves into the spatial and temporal variations in terrestrial
water reserves and green water usage efficiency. Additionally,
the Tobit model is introduced to investigate the influencing
factors of water resource utilization efficiency. The primary
findings of the study are outlined below: The spatial
distribution of terrestrial water resources in the three
northeastern provinces reveals a clear north-south gradient,
with abundant resources in the northern regions and scarcity in
the southern parts. Seasonal fluctuations, albeit present, are
relatively modest, with higher water storage levels typically
observed in spring and summer, and lower levels in autumn and
winter. Regarding the static water use efficiency among the 34
prefecture-level cities, Panjin stands out with the highest
efficiency, whereas Qiqihar ranks lowest. Notably, 91.18\% of
the cities exhibit medium to high efficiency levels, reflecting
commendable performance in water utilization throughout the
region. Almost half of the cities have experienced an
improvement in their water use efficiency compared to the
previous year, signaling a gradual enhancement in water
utilization capabilities. The average total factor productivity
across the three northeastern provinces stands at 1.012,
representing an annual growth rate of 1.2\%. The efficiency of
water resource utilization in these provinces is intricately
linked to the technological progress index. To enhance water
resource utilization efficiency, it is imperative to introduce
advanced technologies, increase research investments, and foster
technological advancements.}",
