Abstract:

This paper attempts to analyze the effectiveness of MQS on quality improvement and its influence on social welfare, based on a duopoly model with vertical
differentiation of quality. Our research indicates that the effectiveness of MQS is significantly influenced by the technology gap between firms as well as regulation efficiency, and it has differentiated impacts on different firms. Under the background of large technology gap between foreign and domestic firms, the government will face a dilemma: setting a low MQS or loosening regulation. Interest conflicts also exist between firms and consumers, and between different firms as well. Solutions to the problem include helping domestic firms narrow the technology gap and continuously improving regulation efficiency.

Key words: vertical differentiation , technology gap , government regulation

摘要：

本文通过构建基于纵向质量差异的双寡头竞争模型，分析了最低质量标准政策对质量提升的作用机制及其福利影响。研究结果显示，最低质量标准政策的效果会极大地受到企业之间技术差距和政府监管效率的制约，并且对不同企业会产生差异化的影响。在国内外企业存在较大技术差距的背景下，政府在实施最低质量标准政策时会遭遇降低质量标准或者放松监管的两难困境，并且会在生产者和消费者，以及不同的厂商之间产生利益冲突。解决上述问题的关键在于提升监管效率的同时，缩小国内外企业之间的技术差距。
