The cognitive level of farmers in rural toilet revolution affects the implementation effect of toilet revolution.In or-der to effectively measure the cognitive level of farmers in rural toilet revolution,the scale is designed on the basis of con-cept definition and dimension identification,and the reliability and validity of the scale are verified by factor analysis and structural equation model.The results show that:1)Farmers'cognition of rural toilet revolution refers to farmers'subjective feelings and comprehensive evaluation of the four dimensions of toilet reform policy,toilet reform standard,toilet reform benefit and toilet reform cost through personal perception and reasoning judgment after they understand the relevant knowl-edge of rural toilet revolution.2)The farmers'cognition scale of rural toilet revolution is composed of four dimensions:policy cognition,benefit cognition,standard cognition and cost cognition,and 15 measurement items.According to the analysis,the level of policy cognition is the highest,and the level of cognition of farmers is the lowest.3)The Cronbach's Alpha coeffi-cient of the measurement factors is 0.901,and the KMO value is 0.801.The reliability of the scale is good,and each factor can explain the farmers cognition.4)Policy cognition,benefit cognition,standard cognition and cost cognition explain the farmers'cognition of rural toilet revolution at the levels of 84%,80%,72%and 77%.Accordingly,the farmer's cognitive model of the rural toilet revolution can accurately measure the cognitive level and formulate it for the government.
