Abstract: An effective way to improve policy sustainability and rationality is via scientifically quantifying non-market social-ecological benifits brought by water-saving irrigation technology. Here,we take Minqin county,downstream of the Shiyang River,as an example,and designed and implemented choice experiments based on a benefit evaluation framework and index system. We then estimated the social-ecological benefits of technology water-saving irrigation adoption using a mixed logit model. The results show that residents of Minqin have formed the cognition of ecological protection,and they expect to take necessary measures to ensure the stability of the ecology and environment. The average willingness to pay for urban households is 657.21 CNY/year,and the average willingness to pay for rural household is 587.06 CNY/year, under the assumption that the ideal level of socio-ecological indicators can be reached through water-saving irrigation technology adoption in the next 10 years. We calculated that water-saving irrigation technology adoption could bring 394.6 million CNY of social-ecological benefits for county residents in the next 10 years,and total the benefits per unit area of farmland is 7674 CNY in Minqin. We point out that choice experiment methods have advantages of reducing measurement bias,acquiring more preference information,and also dealing with multi-index questionnaires more flexibly. However,in terms of selecting evaluation indicators,setting indicator levels,and measuring social-ecological benifits of a wider range of residents in the surrounding areas,more thorough work is needed.
