Over the past 10 years, food safety incidents have occurred frequently in China. Food safety issues in the dairy sector have increasingly gained the attention of the Chinese government and the public. The objective of this research is to explore consumption changes of dairy products of different income groups after these dairy safety incidents.
The research indicates that consumers' response to dairy safety risk is very intense. Dairy consumption has experienced a declining trend in recent years, and the impact of dairy safety incidents has lasted for at least 5 years. Until 2012, dairy consumption had not yet fully recovered from this influence. Using the random effects model, this study examined the relationship between food safety incident and consumption.
Overall, the results show that consumers in the low-income group are more sensitive to safety risk than those in the high-income group. It can be seen from this paper that the decrease of urban residents' dairy consumption was mainly driven by changes in fresh milk consumption, while the decline of milk powder consumption, which was affected by the melamine incident, was relatively moderate, and milk powder consumption for the high-income group even increased.
在过去十年间，中国食品安全事件频发。乳制品行业的食品安全问题日益受到中国政府和公众的关注。本研究的目的是探究这些乳制品安全事件后不同收入群体乳制品消费的变化情况。
研究表明，消费者对乳制品安全风险的反应非常强烈。近年来乳制品消费呈下降趋势，乳制品安全事件的影响至少持续了5年。直到2012年，乳制品消费尚未完全从这种影响中恢复过来。本研究使用随机效应模型检验了食品安全事件与消费之间的关系。
总体而言，结果表明低收入群体的消费者比高收入群体的消费者对安全风险更敏感。从本文可以看出，城镇居民乳制品消费的下降主要是由鲜牛奶消费的变化驱动的，而受三聚氰胺事件影响的奶粉消费下降相对温和，高收入群体的奶粉消费甚至有所增加。
