The Food and Agriculture Organization of the United Nations (FAO) has pointed out that around 1/3 of the food is lost or wasted every year, which is as high as 1.3 billion tons. The expired food disposed by the supermarket is an important part of food waste. The hot sale of temporary food provides a plan to reduce food waste in this link. In foreign markets, there is a relatively mature business model for the disposal and sale of temporary food. The Report on the Current Situation of the Operation of Temporary Food in the Market (hereinafter referred to as the Report) issued by the China Chain Store Association in January 2023 shared foreign experience from "offline retail channels" and "online channels" respectively. The Report points out that Wefood, the first surplus food supermarket in Copenhagen, Denmark, opened in 2016, and specializes in providing or selling surplus food and temporary food. The price of goods is 30% to 50% cheaper than that of ordinary supermarkets. It is estimated that Wefood supermarket can reduce the food waste of 700000 tons per year for Denmark. The first "anti food waste" store established in Paris, France in 2018, reduces food waste by "recycling products from traditional distribution channels". The app of "Too Good To Go" was launched in Denmark in 2016, and stores such as chain retailers, food supermarkets, restaurants, bakeries, cafes, etc. were settled. These stores will sell the food that has not expired but needs to be processed that day at a discount, and the restaurant will use this app to sell the remaining food. In the domestic market, in recent years, "anti food waste" has gradually become a trend, and the concept of sustainable consumption has gradually penetrated into the consumer layer. More and more consumers have become more rational in their consumption concept, and gradually accept temporary food. In the Little Red Book, more than 10000 notes about temporary food have been shared. On the social platform Douban, the "I Love Temporary Food Group", founded in September 2020, has attracted more than 90000 temporary food followers to exchange and share their experience in purchasing temporary food. They call themselves "temporary food workers". The market potential of temporary food has attracted the attention of society and consumer retail industry. In the past two years, e-commerce platforms and chain discount stores mainly selling temporary food have gradually emerged. According to the Report, conservatively estimated by 1% of the inventory in the snack industry every year, the scale of China's temporary food industry was about 22.2 billion yuan in 2016 and about 30 billion yuan in 2020. From 2016 to 2020, the compound annual growth rate of the market size of the temporary food industry was 7.8%, from which it was estimated that the market size of the temporary food industry in 2026 would be about 47.1 billion yuan. The physical retail enterprises represented by chain supermarkets and convenience stores, while seizing the market opportunities and exploring the path of transformation and innovation, actively assume social responsibilities, reduce food waste and develop low-carbon. Chain supermarket and convenience store enterprises have generally carried out measures to reduce waste. On the one hand, they have strengthened the management of purchase, sales and inventory, improved the new technology of digitalization and sales forecast, upgraded the internal validity management system, improved the efficiency of the supply chain, and reduced the waste of inventory and purchase. On the other hand, from the perspective of marketing, they have carried out discount promotions to reduce waste. And precise commodity positioning and order quantity control, early warning and
