集体声誉下最低质量标准的福利效应

The Welfare Effect of Minimum Quality Standard under Collective Reputation

本文针对集体声誉行业的特点构建两阶段博弈模型,从竞争效应和质量效应两个方面系统考察了集体声誉下最低质量标准规制的福利效应。结果发现,最低质量标准通常具有的反竞争效应在集体声誉行业并不存在,适度并偏高的标准在提高质量水平的同时反而会增加行业当中的企业数量和改善社会福利。最后,结合我国乳品新国标的例子,对运用最低质量标准规制解决我国集体声誉行业普遍存在的质量问题提出了政策建议。

The results showed that, the anti-competitive effect which minimum quality standard usually has does not exist in the collective reputation industry, moderate and high standard can improve the quality, increase the number of companies in the industry, and improve social welfare. Finally, with the example of China＇s Dairy new GB, this paper gives policy suggestions on how to use minimum quality standard regulation to resolve the quality problems which are ubiquitous in China＇s collective reputation industry.
