基于国际贸易的中国产品质量溢价研究

Research of China's Product Quality Premium Based on International Trade

本文从国际贸易的角度研究了主要国家出口产品的质量溢价水平,以及宏观质量水平的变动对经济发展的影响程度。理论层面,首次提出了质量溢价概念,分析了质量与价格之间的逻辑关系,并论证了质量提升与经济增长之间的互动关系。实证层面,首先基于国际贸易数据计算各国出口产品的平均单位价值,然后对主要国家出口产品的质量溢价和质量溢价率进行了测度。分析发现,与主要发达国家相比,中国以输出中低档质量的产品为主,但每一次出口产品质量水平的明显提升都对中国经济增长发挥了积极支撑作用。在理论与实证研究结果的基础上,提出了中国提升产品质量的政策建议。

This paper studies countries＇ quality premium of export products, and impact on economic development when macro-level of quality changes from the perspective of international trade. For theoretical level, the paper firstly pro- poses the concept of quality premium, and analyzes the logical relationship be- tween quality and price; and further demonstrates the interaction between quality improvement and economic growth. For empirical level, the paper firstly calcu- lates countries＇ average unit value of export products based on intemational trade data, and then measures quality premium and quality premium rates of export products. Compared with the major developed countries, we find that China pri- marily export middle or low quality products, but each significantly improvement on the level of export product quality has played a positive role on the econom- ic growth of China. Based on theoretical and empirical research, this paper fur- ther clarifies four basic conclusions, and puts forward policy recommendations to improve China＇s product quality.
