Abstract Water footprint is a new concept reflecting people’s real consumption and usage of water resources. It profoundly posts the real water consumption of social economic system and offers a new viewpoint for water resource management. In this paper, the concept of water footprint is put forward, together with its calculation methodologies. Taking Xinjiang Province in northwest China arid areas as an example the authors investigate the variation of water footprint from 1990 to 2005; then using ADF unit root test and cointegration analysis methods of dynamics econometrics to analyze the relation of water resources utility efficiency with water footprint and consumption pattern. The results indicate that gross water footprint has increased from 115.55×108 m3 to 159.57×108 m3 from 1990 to 2005, which showed a ascending tendency; the intensity of water footprint has decreased from 0.42 m3 per Yuan to 0.06 m3 per Yuan under countrywide average level, which showed that water resources utility efficiency has obvious elevation. Generally, the consumption level, quantity, patterns of urban and country citizens have obviously changed. The relationships between low efficiency of water resource utilization and water footprint, consumption pattern have a long-run and stationary tendency, which need timely rational control by adopting corresponding strategy and countermeasure.
