With the irrigated areas around Yanmen in Shanxi as the research object, analysis of influencing effect of the farmer’s and government’s conducts in irrigation has been made by taking such main influencing elements on irrigation as investment of watersaving irrigation technology, agricultural water price, governmental allowance, water right and association of water users according to the multielement sequencing model. The results of analysis show that the water price and governmental allowance are much greater than irrigating technology, exchange of water right and associations of water users to influence the farmer’s and government’s conducts. Moreover, an optimization of the farmer’s conduct contributes more than government’s to promotion of social welfare.
