Abstract: Water shortage and water pollution have become a restrictive factor of sustainable development in Beijing, and water resource utilization has aroused much attention. Water footprint study links the production and consumption to the use of water resources, and can reveal the comprehensive utilization of water resources. Based on the water footprint, this study assessed the water resource utilization of Beijing, and the results showed that: (1) In 2012, the water footprint in Beijing was 35.26 billion m³, and the per capita water footprint was 1704 m³, far beyond the total water volume of 3.59 billion m³ and per capita consumption of 193.3 m³ in the statistics. Thus, the water resources were under enormous pressure. (2) The virtual water consumption of urban and rural regions was different. Except the animal products, the rural residents’ virtual water consumption of food was relatively high, with 103.5 m³ per year per capita, while urban per capita annual was 72.5 m³, lower than the dried and fresh fruits of 92.4 m³. (3) Animal products accounted for the largest proportion of the virtual water consumption, which illustrated the relatively high consumption of animal products of Beijing residents and the high virtualwater content of animal products per unit. For this reason, it may be appropriate to increase imported animal products to replace local animal products in the virtual water trade, reducing the consumption of water resources.
