摘　　要： 分析无回答误差产生的原因和影响,在抽样调查的过程中,结合市场调查的次序和方式采取无回答误差的预防措施。对已经产生无回答的数据,用样本替代法和加权调整法对缺失数据进行调整,这两种方法都提高了调查数据的可靠性和准确性,有效降低无回答率。 In sample survey, non-response will bring about the distortion of survey data, and result in the failure of the survey. Therefore it is of theoretical and practical significance to analyze the causes of non-response errors and study the methods of lowering non-response rate. There are two ways to improve the reliability and accuracy of the survey data and reduce non-response effectively. First, adopt measures to prevent non-response errors combining the order and style of market survey in the process of sampling; second, adjust the missing data through sample substitution method and weight adjustment method.
