Beijing is a city which is short of water seriously. The rapid growth of population together with the increasing competition for water between agriculture, industrial and urban use results in unprecedented pressures on water resources in Beijing. In order to ensure the sustainable development of Beijing, we must implement strict water resource management and increase water use efficiency substantially.

To use water resources efficiently in Beijing, we needed to analysis the water using data of Beijing in detail. The purpose of this paper is to provide decision making basis for management of water resource and adjustment of industrial structure in Beijing. In this paper, we uses the data provided by Municipal Water Bureau and Beijing Statistical Bureau, together with the actual situation of water in Beijing, makes quantitative analysis of water resource of Beijing. Based on the theory and method of water resources accounting, this paper establishes water accounting framework by combining the idea of water resources accounting and input-output accounting to make input-output analysis for water resources.

Combing the water use data and input-output table, we can construct the water input-output table. Then, based on the water input-output table, we can divide all sectors into four categories: the first category is those sectors whose economic contribution were high, but their water use extent are also high; the second category is those sectors whose economic contribution was high, water use level was low; the third category is those sectors whose economic contribution was high, and its potential water use level was also high; the fourth category is those sectors whose economic contribution was small, but water use level was very high. Our purpose is to explicit which sector's development should restrict in the water resources management process and which sectors should be encouraged in the future and so on.
