In order to clarify the paths and methods for involving the contract water-saving quantity in the water right transaction, the feasibility analysis of water right transaction is carried out from the institution basis and transaction mode according to the characteristics of direct and indirect water users. The direct water users can conduct various transactions of regional water right, water withdraw right and irrigation water right. The indirect water users will also have great transaction potential if their water-disposing right and storage right of contract water-saving quantity for professional water-saving companies are determined. Based on the stakeholder analysis, it is put forward that the establishment of water right system and the financial support are the design priorities for the relevant water policies. The water right system should include registration, empowerment and circulation of water right. The financial support policies should be developed from the government funds, participation of social capital and reduction of tax loads on enterprises.
