Food is the paramount necessity of the people, while food safety is the priority . Facing the increasingly serious food safety problems in China, how to improve food safety has become the responsibility of the whole society, and also the obligation of social development . Based on the 8000 residents' survey data, the ordinal logistic model was used to analyze the residents' satisfaction with food safety . The results show that residents are generally worried about food safety, and there is a strong demand for safe food . Gender, age, educational background, supervision, publicity, and complaint handling significantly affect residents' food safety satisfaction . In terms of income heterogeneity, low-income residents have the highest degree of satisfaction with food safety . With the improvement of income level, their degree of satisfaction is decreasing . The high-income class residents have a strong consciousness of rights safeguarding after purchasing unsafe food . For low-income residents, their awareness of rights protection is declining due to insufficient income . In the way of rights protection, most respondents choose to return or refund money after negotiation with the seller . The lack of punishment for unscrupulous sellers is one of the main reasons for the frequent occurrence of food safety problems in China.
