最小质量标准及其设计

Minimum Quality Standards and Its Design

讨论了基于市场消费者结构的社会福利最大化下的最小质量标准设计。通过分析最小质量标准(MQS)引入后特定市场消费者结构下进口企业和本国企业之间的质量竞争,探讨了设置不同水平的MQS所导致的博弈均衡演变以及由此引起社会福利的变化。采用数值算例,依据市场消费者结构的分布特征,计算不同水平MQS下市场的博弈均衡解,通过比较均衡下的社会福利水平来设计最小质量标准。

Based on consumer structure, the Minimal Quality Standards （MQS） under the condition of maximizing social welfare was discussed. This study explored the evolution of game equlibrium under different MQS and the change of social welfare, by analyzing the quality competition under specific MQS between foreign companies and native companies. And then, by numerical examples, the game equlibrium was computed, and the level of social welfare under different MQS was compared according to the distribution characteristic of consumer structures, so the optimal MQS could be designed.
