- Abstract：Based on the idea of benchmarking in public service sector, a benchmark system of water resources utilization efficiency was constructed for prefecture-level cities in China from 2007 to 2014. On this basis, this paper conducted an evaluation of city water resource utilization efficiency of Hebei Province from 2007 to 2014 in order to investigate specific location and change trend for water consumption per unit GDP (10000 CNY), water consumption of industrial output per unit GDP (10000 CNY), per capita water consumption and per capita residential living water consumption of cities in Hebei Province in all prefecture level cities in China of different type. At the same time, water resources utilization efficiency benchmarking system is extrapolated according to its historical trend. The benchmark prediction results are used as the water-saving efficiency management objectives of each city in Hebei Province, combining with population growth and social economic development planning goal in Hebei Province. We have estimated water demand in the "13th Five-Year" final year (2020) at city level in Hebei Province in order to provide reference for making a guidance of water resources management strategy in Hebei Province.The results show that:water consumption per unit GDP (10000 CNY) of Tangshan City, Cangzhou and Langfang of Hebei Province has been in the advanced level of the whole country, water consumption of industrial output per unit GDP (10000 CNY) of Cangzhou has always been in the advanced level of the whole country, per capita water consumption of Baoding, Cangzhou and Hengshui has been in the advanced level of the whole country, and per capita residential living water consumption of Baoding, Cangzhou, Zhangjiakou, Shijiazhuang, Qinhuangdao and Xingtai has been at the advanced level of the whole country. It is expected that by the end of the "13th Five-Year" period, the total amount of industrial water demand in the cities of Hebei Province will reduce to 881 million m3, the living water demand of residents will increase to 426 million m3,and the total water consumption of cities in Hebei Province will increase to 1694 million m3.
