“…By the end of 2019, the total water consumption in the Yangtze River basin was 206.45 billion m 3 . Among them, the industrial water consumption was 70.40 billion m 3 , accounting for 34.1% of the total water consumption [21][22]. And the industrial water con-sumption in the study area was 8.641 billion m 3 , the industrial wastewater discharge was 859 million tons, accounting for 10% of the total industrial water consumption [23].…”

Exploring ways to improve the green efficiency of industry water resources (GEIWR) is an inevitable requirement for achieving harmonious and sustainable industrial development and water use. Taking the urban agglomerations in the middle reaches of the Yangtze River (UAMRYR) as an example, this paper constructed an industrial green water resource efficiency index system. Based on the slack based model (SBM), the spatiotemporal evolution characteristics of the GEIWR during 2006-2019 were analyzed, and its spatial differentiation characteristics were investigated by exploratory spatial data analysis (ESDA), Besides, a spatial Tobit model was constructed to reveal its influencing factors. The results are as follows: (1) Temporally, the GEIWR ranged between 0.525 and 0.745 from 2006 to 2019 with an overall flat change, showing two distinct phases of change. Spatially, the difference varied markedly, with the GEIWR showing a pattern of "high in the south and low in the north" from 2006-2010 and "high in the centre and low around" from 2014-2019. ( 2) GEIWR global Moran's I value between 0.003 and 0.462, showing positive correlation characteristics, but the coefficient gradually decreased and the spatial correlation decreased; The local autocorrelation aggregation region changed significantly, the spatial aggregation effect was apparent before 2014, the concentration area decreased in 2019, the spatial correlation decreased, the spatial disequilibrium appeared. (3) The economic and industrial structure and the level of science and education had a significant effect on GEIWR and the economic benefits of industrial water resources showed an inverse inhibitory effect, while the natural resource endowment and degree of industrialization had no significant impact on GEIWR.

“…Existing studies have probed into the various factors that influence water efficiency, including water resource per capita, economic level, industrial structure, foreign investment, urbanization level, and even environmental regulation [21,[23][24][25]. Additionally, scholars have paid attention to the effect of water price on water-use efficiency [26].…”

With a huge capital and labor input influx, inter-basin water transfer (IBWT) projects have been shown to effectively mitigate water stress and ensure the water demand for social and economic development in the receiving area. Whether they have promoted the improvement of regional water use efficiency (WUE) is crucial for sustainable management of regional water resources. Targeting the South-to-North Water Transfer Project (SNWTP), the largest and most ambitious inter-basin water transfer project in China, this study establishes quantitatively econometric models to analyze the impact of different water diversion projects, specifically the eastern route of the SNWTP (ER-SNWTP), middle route of the SNWTP (MR-SNWTP), and diversion from the main stream of the Yellow River (DYR), on the regional water consumption per unit of GDP; regional water stress, water use structure, economic structure, and urbanization level are used as control variables in different types of cities in the Yellow River Basin, and some intriguing results are found. While the overall water transfer project demonstrates a positive impact on water use efficiency, the effects of the three water transfer measures vary significantly. The ER-SNWTP does not exhibit a notable positive effect on regional water use efficiency, whereas the MR-SNWTP demonstrates a significant positive impact. Interestingly, the DYR has a notable negative influence on water use efficiency in developed cities. The water use structure, shaped by the pricing, scale, and policies of different projects, emerges as a pivotal factor in explaining these differences. Finally, this paper suggests that the impact of water transfer projects on the improvement of regional water use efficiency be viewed from a more comprehensive and developmental perspective.

“…Generally speaking, the construction of the Yangtze River Economic Belt is the best choice to promote the economic development layout of the Yangtze River Basin (Lu, 2014). For example, some scholars believe that after the establishment of the Yangtze River Economic Belt strategy, the water use efficiency of the Yangtze River Economic Belt has dramatically improved (Liu and Yuan, 2022). Some scholars have also proved through research that the strategic Policy of the Yangtze River Economic Belt reduces the local water ecological footprint, which is more significant in developed areas than in developing areas, and more effective for agriculture than for industry (Luo et al, 2019).…”

As a regional development strategy based on the world’s third largest river basin unit, the Yangtze river economic belt strategy plays a vital role in building ecological civilization with the core concept of “ecological priority and green development”. To study the impact of the Yangtze River Economic Belt strategy on the construction of ecological civilization in the upper reaches of the Yangtze River. This paper uses the entropy power method to measure the level of ecological civilization construction in 37 prefecture-level cities in the upper reaches of the Yangtze River. It examines the impact of the Yangtze River Economic Belt Strategy on the construction of ecological civilization in the upper reaches of the Yangtze River based on the DID method. The study results show that 1) the level of ecological civilization construction in the Yangtze River’s upper reaches has continuously improved from 2003 to 2020. 2) The implementation of the Yangtze River Economic Belt Strategy has a significant positive impact on the construction of ecological civilization in the upper reaches of the Yangtze River. 3) The Yangtze River Economic Belt Strategy can promote the construction of ecological civilization in the upper reaches of the Yangtze River by improving the level of science and technology innovation. 4) The implementation of the Yangtze River Economic Belt Strategy does not significantly impact the level of ecological civilization construction in the regions participating in the Belt and Road Initiative, so it is necessary to pay attention to the synergy between different policies. This study will help to raise the awareness of developing countries on economic development and ecological protection in the river basin, and provide a reference for policymakers.
