市场中不同的竞争关系决定了零售价格呈现不同的波动形态,进而对消费者福利产生不同的影响。本文以猪肉为例,研究猪肉零售价格对消费者的影响。通过对山东省青岛市猪肉零售价格进行分析后发现,由于价格周期性波动产生的原因在于零售企业之间的动态竞争。因此,周期性价格波动比稳定价格为消费者带来了更高的福利。因此,公共政策部门在制定平抑产品零售价格波动政策之前需要研究价格波动的成因,对症下药,才能起到保护消费者福利的效果。
The different competitive relations in the market determine the different fluctuation patterns of retail prices, which in turn have different impacts on the welfare of consumers. This article takes pork as an example to study the impact of pork retail price on consumers. Through the analysis of the retail price of pork in Qingdao, Shandong Province, it is found that the reason for the cyclical fluctuations in prices lies in the dynamic competition among retailers. As a result, cyclical price fluctuations provide consumers with higher benefits than stable prices. Therefore, public policy departments need to study the causes of price fluctuations before formulating policies to stabilize the retail price fluctuations of products so that the right policies can help protect the welfare of consumers.
