Abstract In order to decide if the weight of an index for comprehensive evaluating operation perfor-mance of irrigation district is reasonable and to consider whether the outcomes of an evaluation are rational and scientific, we apply subjective analytic hierarchy process and objective variation coefficient method into determination of a series of weight based on game theory in this paper. Then we integrate these individual weights into final weights. Further, based on the driving force-state-response model, we build a comprehensive evaluation system to assess the operational performance of a large irrigation district. At last, we evaluate the operational condition of Jinghui Canal Irrigation District in Shaanxi by means of this system. The results show that the decided comprehensive weights can involve decision-makers′ subjective requirements but also can represent the actual operational circumstance of an irrigation district. Besides, the evaluating process is simple, scientific, objective, and universal, so it can provide a proper evaluation for the operational situation of an irrigation district.
