Based on the qualitative feature sensitivity randomization model—Warner model under stratified sampling,this paper uses the joint ratio estimation method to theoretically derive the estimators and estimation errors of the survey proportion of sensitive issues.Through efficiency comparison,it is concluded that the precision of the joint ratio estimation method is better than that of the stratified estimation method when the sample size of each layer is large and the ratio estimation is effective.The results of investigation show that the above conclusions are correct.
