Development of Policy Analysis Tool for Developing Cities Confronted by Urban Water Issues : Water Accounting Tables and the Applications to Chinese City

作为促进亚洲发展中国家快速发展的城市综合水资源政策的信息基础设施，该项目旨在首先编制城市水资源核算表，然后利用该表开展与水资源有关的政策研究。北京市在1987-2005年间建立了水资源核算表。根据几项带有表格的实证研究，水价的提高和促进节水的政策与产业结构转型导致北京大宗商品进口增加相吻合。结果表明，工业用水需求下降，污水处理成本降低，增加了社会效益，甚至增加了居民和商业用水需求。

As an information infrastructure to facilitate the integrated water policies for rapidly growing cities in developing countries in Asia, the project aimed at developing urban water accounting table first and then conducting water related policy studies with the tables. The water accounting tables have been constructed in Beijing during the period between 1987 and 2005. Based on several empirical studies with the tables, increase in water prices and policies to promote water savings coincided with industrial structure transformation leading to increase in commodities imports to Beijing. As a result, it is found that social benefits are increased due to decline of industrial water demand and decrease in wastewater treatment costs, even water demand in residential and commercial sectors are increased.
