Online distribution of questionnaires is the product of modern scientific and technological informationization. Its advantages are that it is more convenient than mailing questionnaires, and the data can be computerized immediately, eliminating the workload of data entry and possible human errors in the process of entry. The disadvantage is that the respondents of the online questionnaire survey can't communicate directly with the researchers, and the respondents' answers to the questionnaire will vary widely due to their own qualities, which affects the reliability and validity of the questionnaire to some extent.
For the recovered questionnaires, the recovery rate of valid questionnaires should be counted while eliminating invalid questionnaires. Maintaining a high questionnaire recovery rate (that is, the effective questionnaire rate) is also the guarantee for us to obtain true and reliable information. Generally speaking, if the recovery rate is only about 30%, the data can only be used as a reference; More than 50%, you can adopt suggestions; When the recovery rate reaches more than 70-75%, it can be used as the basis for research conclusions. Therefore, the recovery rate of the questionnaire should generally not be less than 70%. In addition, if possible, we can do a small-scale follow-up survey or interview survey to understand the true views of respondents who have not answered questions and prevent the one-sidedness of questionnaire results analysis.
The main factors affecting the questionnaire recovery rate are: the effectiveness of questionnaire recovery, the rigor of survey organization, the attractiveness of survey topics, the difficulty of filling in questionnaires and the controllability of questionnaire recovery. According to statistics, the recovery rate of mailing questionnaires is about 30-60%, while the recovery rate of sending questionnaires in person can reach 80-90%. If you send it and collect it yourself, you can check whether the questionnaire is empty, missing or obviously wrong, so that you can correct it in time to ensure the high effectiveness of the questionnaire. Therefore, in order to improve the recovery rate of the questionnaire, it is necessary to design a short, concise, attractive and easy-to-use questionnaire, and it is best to send the questionnaire face to face.

Questionnaire survey is a common method in empirical research and has made great contributions to social investigation and research. In the application of questionnaire survey, there are many factors that affect the survey quality. This paper summarizes various matters needing attention in the application of questionnaire survey method, including the general principles of questionnaire design, matters needing attention in using existing scales and self-designed scales, and matters needing attention in issuing and recycling questionnaires. We must pay attention to these problems in order to improve the quality of investigation, give full play to the role of questionnaire investigation and achieve better research results.
