Objective To construct a set of scientific, reasonable and operable index system for municipal food safety supervision, level evaluation index system, to provide a reference for the precise evaluation of food safety supervision level of various cities. Methods Based on the experience of establishing food safety demonstration counties in Zhejiang province, the evaluation index system was determined by using balanced scorecard theory and network analytic hierarchy process (AHP) through field research method, literature and expert interview. The system was applied to evaluate 11 cities in Zhejiang province. Results The weights of the four first-level indicators of work performance, relevant stakeholders, internal management and learning and growth are 0.107 6,0.343 9,0.488 3 and 0.062 1 respectively. Under the first-level indicators, there are 10 second-level indicators and 51 third-level indicators. The evaluation result of 11 cities are consistent with the evaluation result of Zhejiang food safety work in 2020. Conclusion The evaluation index system can scientifically and objective ly evaluate and reflect the level of food safety supervision in each city.
