The food safety regulation has become the important measurement to assure food safety. Although some scholars have studied the related topics both in the consumers' willingness to pay and the ways to increase enterprises' long-term efficiency, it is still lack of relevant studies on the food industries' welfare loss arising from regulation. The purpose of this study was to do in-depth research on welfare losses of pork, beef and mutton, and poultry manufacturers using the horizontal displacement model. The results showed that producer losses were higher for meat products with smaller own-price elasticity and more consumption quantities. The losses of pork manufacturer were the largest-￥304869 billion-, which was about 876% of its total sales revenue, followed by the losses of poultry manufacturer-￥69142 billion-, 545% of its total sales revenue. The beef and mutton manufacturer have the lowest losses-￥68560 billion-, 960% of its total sales revenue. The results also showed that for different meat products, the increase cost per unit product and upward pressure on prices were different. For every kilogram pork, beef and mutton, and poultry, the highest increase cost amount was ￥107, ￥161, and ￥063, respectively, and the price upward pressure was 876%, 960%, and 545%, respectively. Based on the conclusion, this study suggests that it is necessary to effectively control the welfare loss and execution cost.
