Policy conflict analysis of water quality improving for the transboundary regions of Guanting reservoir

In the paper,the water conflict in transboundary regions of Guanting reservoir watershed is studied.The conflict model is obtained by using the conflict analysis techniques of Fraser and Hipel,in which thore are three sides concerned,the central,the upstream and the downsteam government Out of 18 possible out comes,the partly cooperative outcome and the fully cooperative one are optimized by analyzing the preferences of each side and the stability of their outcome.And the fully coop erative out come will be most likdy to occur,which shows that with coordination of the central government using the stimulus and strategy,the cooperation between the upstream and downstream government can improve the status of water resource,i.e,the upstream to reduce pollutant completely and the downstream to give financial support.
