The paper combined traditional water input-output table with data of water intake in order to construct water resource input-output table of Luanhe River Basin in 2002 and 2007.Then it analyzed the utilization efficiency and benefit, inter-sector water transaction coefficient, virtual water trade and total water consumption of the three industries systematically based on the input-output method of water resources. The results showed that ① The first industry directly uses water and has low efficiency; ② The second and third industries indirectly use water and have higher efficiency. The indirect water of the second and third industries is mainly from the first industry.But in aspect of water efficiency, the efficiency of first and second industries is higher and that of the third industry is very low. The efficiency and benefit of water use of 2007 was higher than that of 2002; ③ The study area is a net exporter of virtual water trade，and the quantity of trade rised from 2002 to 2007.The proportion of the first industry is the largest and its quantity has increased about 77%.At the same time,the third industry has the smallest proportion, and the quantity of input close to that of output;④ The total of virtual water consumption of 2007 is two times that of 2002.
