Objective To provide basis for further improvement of China's national food safety standards system， the special follow-up evaluation results of national food safety standards in 2020 were analyzed， and the comprehensive evaluation of standards by regulatory authorities， industry enterprises and other parties were systematically understood.Methods Opinions were collected through the online questionnaire survey. Excel 2016 was used to sort out the collected comments and descriptive statistical analysis. Meanwhile， the results were compared with those of 2019 to get the trend analysis results.Results A total of 17 074 special follow-up evaluation questionnaires of national food safety standards were collected on the online platform， with the highest participation of personnel from food production and operation enterprises， accounting for 50.1%（5 917/11 810） of the total number of valid questionnaires. 93.0%（9 363/10 067） of the respondents thought that the food categories could be clearly positioned in the current general food safety standards. 84.2%（9 942/11 810） and 61.5%（7 260/11 809） of the respondents thought that there were corresponding food product standards and code of practice standards， respectively. The comprehensive score of product standards was 4.41， and the comprehensive score of code of practice standards was 4.42.Conclusion China’s current food safety standards system framework is basically established. All parties are generally satisfied with China’s national food safety standards system， but there are still some problems in the standards system that need to be further improved. It is suggested to carry out the food safety standards follow-up evaluation in depth and make full use of its results， and improve the national food safety standards system in the future.
