中国体育产品出口质量的测算及对出口贸易额的影响

Measurement of Chinese Sporting Products’ Export Quality and Its Impact on Export Trade Value

本文基于改进的回归反推方法,使用UN Comtrade数据库中HS六位编码下6类体育产品数据,首次系统测算了“年份—中国—主要经济体—产品”四维的体育产品出口质量,并采用引力模型考察体育产品及分类产品出口质量效应对出口贸易额的影响,研究结果发现:(1) 2000年至2020年,中国体育产品出口质量仍处于较低水平,但是出口质量呈现波动上升的趋势。(2)从重点出口市场来看,中国出口至主要经济体的体育产品出口质量具有差异性,这种差异不仅体现在整体体育产品上,还体现在分类体育产品上。(3)对于整体体育产品而言,出口质量效应正向显著;按细分产品分组后,出口质量效应存在一定的异质性,但是主要表现为正向显著,尤其是HS420、HS640以及HS9506类产品的出口质量效应非常显著。

Based on the data of six categories of sporting products,under the HS code in the UN Comtrade database,this paper uses the improved regression model to compute the export quality of Chinese sporting products in terms of "year,China,major economy and product",and uses the gravity model to investigate the impact of export quality effects of sporting products and classified products on export trade value. The findings are:(1)From 2000 to 2020,the export quality of Chinese sporting products is at a relatively low level,but the export quality has a fluctuating upward trend.(2)From the perspective of key export markets,the export quality of Chinese sporting products exported to major economies is different,which is reflected not only in the overall sporting products,but also in the classification of different sporting products.(3)For the overall sporting products,the export quality effect is significant;for the subdivided products,the export quality effect has some heterogeneity,but it is mainly positive and significant,especially the export quality effect of HS420,HS640 and HS9506 products is very significant.
