运用倾向得分匹配法分析江苏和河南1 076户农户参与灌溉管理行为层次对灌溉系统和作物生产的影响。结果表明:(1)操作规则、集体选择规则和宪政规则,3个规则层面的农户参与行为都对灌溉系统产生积极影响,随着农户参与规则层次的提高,灌溉系统绩效的改善更加显著,表现为灌溉及时性更高、灌溉设施维护情况更好,但灌溉服务质量提高只在宪政规则层面显著。(2)3个规则层面的农户参与行为都促进了作物生产,随着农户参与层次逐级提高,作物生产绩效明显提升,表现在种植面积更大和作物产量更高。因此,增加农户多层次参与有利于促进灌溉管理改革的深入、持续进行。
Based on 1 076 farmers' survey data in Jiangsu and Henan provinces,this paper used PSM (propensity score matching) method to analyze the influences of farmers' participation behavior levels in participatory irrigation management on irrigation system and crop production.Two main results were got.First,farmers' participation behavior in different levels of rules positively influenced the performance of irrigation system.With farmers' participation levels raising,from lower level of operation rules,to higher levels of collective selection rules and constitutional rules,the performance of irrigation system improved more significantly,including higher irrigation timeliness,better maintenance of irrigation facilities,and partly improving irrigation services that performed significantly only in constitutional rule level.Second,farmers' participation behavior was accorded with the improvement of crop production performance.As farmers participated in actions of higher rule levels,better performance of crop production including larger crop planting area and higher crop yields was got.Therefore,policymakers should guide farmers to participate in multi levels of irrigation management in order to promote the sustainable reform of irrigation management.
