产品质量与制造业本地市场效应——基于需求结构视角的经验研究

Product Quality and Local Market Effects of Manufacturing Industry:Based on an Empirical Study from the Perspective of Demand Structure

基于非位似偏好的贸易理论研究表明,收入分布将会通过需求结构影响一国的进出口商品质量结构。本文首先对我国每一细分出口产品的质量类型进行识别,进一步基于通过包含了需求结构因素的重力方程对我国与主要贸易伙伴国在质量竞争型产品双边贸易中是否存在本地市场效应进行检验。结果表明,不同质量类型产品的本地市场效应存在差异;同时,需求结构随需求规模在不同区间呈现对本地市场效应的差异化影响。因此我国应配合当前的需求结构,从供给与需求两方面挖掘我国对外贸易转型的内生动力。

The study of the trade theory based on non-homothetic preferences shows that income distribution structure will affect the quality structure of one country＇s import and export commodities through demand structure. This paper firstly tries to identify the quality type of each subdivided ex- port product, then performs a test to see whether there exist local market effects in the bilateral trade of the quality-competitive products between China and its major trading partners based on the gravity equation containing the factors of demand structure. The results indicate that there exist differences in the local market effects of different types of quality products; at the same time, along with the de- mand scale, the demand structure varies at different places, presenting differentiated impact on the lo- cal market effects. Therefore, China should match up the current demand structure and excavate the endogenous power to transform China＇s foreign trade from the two sides of supply and demand.
