Water footprint evaluation is of guiding significance for the rational development of regional water resources. The input-output method was used to account for the water footprint of Hubei Province from 2007 to 2017, and the driving factors of water footprint changes were analyzed using the structural decomposition model. The results show that the virtual water content in Hubei Province decreased significantly, and water use efficiency improved from 2007 to 2017. The total water footprint showed a trend of rising and then falling, with a net increase of 19.9%, and the main growth sectors were construction and services. Technology level and economic scale were the main factors inhibiting and promoting the increase of water footprint, respectively. However, their effects on water footprint changes gradually weakened, and both showed a reduction effect. From 2007 to 2017, the sectoral linkages changed from positive to negative driving force, and the inhibitory effect on water footprint was revealed, which shows that optimizing the industrial production process helps carry out water conservation. The impact of driving factor on different sectors showed heterogeneity. The adjustment of industrial structure inhibited the increase of water footprint in high water-consuming sectors such as agriculture while promoting the increase in construction and services. In the future, the industry scale and residential demand in sectors producing high-value-added products will grow, such as services, and water-saving technology development should be shifted to these sectors promptly.
