Abstract: Energy and water are highly correlated. In order to break through the limitations of the previous single-resource management policy and improve the effectiveness of related policies, it is urgent to carry out research on energy-water coupling relationship and collaborative management. Based on the system input-output analysis and ecological network analysis, this paper built an energy-water nexus network of Hubei Province in 2007 and 2012. The results are as follows: 1) In 2012, the energy consumption and water use caused by urban final demand were 14 304.93×104 tce and 346.66×108 m3, respectively. Compared with those in 2007, energy consumption and water use induced by urban final demand increased by 52.26% and 7.98%, respectively. About 50% of energy consumption and water use caused by urban final demand were contributed by manufacturing. 2) In 2007, the recycling rates of water networks and energy networks in Hubei Province were all around 2.71%. The recycling rate of water network increased to 4.23%-4.40% in 2012, and the recycling rate of energy network had small variation. 3) The robustness analysis showed that both energy and the water networks are less efficient and more redundant. 4) After taking nexus effect into consideration, the control of production and supply sectors of electric power and heat over most other sectors in the energy and water networks becomes stronger during 2007-2012. The proposed nexus network approach may help bridge the gap between nexus modeling and regional resource management by identifying the regulating pathways for each sector to coordinate with their nexus management.
