This paper contains following studies and results:(1) In the theory analysis and the method analysis of price regulation in water industry, after concluding systemically characters of water industry, the experience of price regulation in water industry of other countries and disadvantages for price regulation in water industry of China, this paper considers that the enterprise conceals the real cost, implicit output and the leaking and losing rate of water pipelines should be settled.

论文的研究工作和结论包括：(1)在供水行业价格规制的理论分析和供水行业价格规制方法分析中，论文主要对供水行业的性质、国外供水行业价格规制的实践经验和我国供水行业价格规制弊端等方面进行了系统的阐述和分析，认为虚报成本、产量隐性和管网漏损率大是目前供水行业价格规制中最突出的问题。

Based on the management principle and objective of Jiangsu SNWDP, the thesis establishes its management framework and designs three management patterns and four modes. Through analyzing the anticipative management effect, scopes in point, advantages and disadvantages of each modes seriatim, the thesis confirms the recommended pattern. It makes framework refinement design, defines rights and duties of control level, execution level and participation level for the recommended pattern. According to the principles of planned water use, metered water use, contract water use, toll water use, it studies project operation for recommended pattern from four aspects, namely water supply plan, measure intensified, water supply contract, and water rate enacted. The thesis analyses and studies how to ensure water supply quality of Jiangsu SNWDP from three levels, including doing watershed protection, intensifying intermediate process, and establishing a long-term mechanism. It makes brief design for dispatching management applied system, studies emphases parts which may affect operation of the pattern in practice, also analyses dispatching optimization of Provincial boundary project management, pumping station management, and different water resources. Finally, the thesis studies relevant basal supports and development stratagems for the management of Jiangsu SNWDP.
