摘要
本文在拓展学者Hallk、Sivadasan、Medin的研究基础上构建了刻画加总贸易成本对出口产品质量作用机制的理论框架[1-2],并采用门槛效应模型从整体和多维异质性视角揭示了加总贸易成本对出口产品质量的实际作用机理。研究结果表明:首先,加总贸易成本对出口产品质量的作用机制呈现出显著的非线性,这种非线性不仅在理论分析框架中成立,在整体层面和区域、地理优势异质性层面均稳健成立;其次,加总贸易成本对出口产品质量既存在“利润侵蚀型负效应”,也存在“倒逼革新型正效应”,但这种倒逼正效应存在一定“天花板”,跨过“天花板”后加总贸易成本增加将显著降低出口产品质量;最后,虽然2002-2015年间中国出口产品质量有所提升,但提升幅度相对有限。提高贸易便利性、科学提升工业规模和提升全要素生产率能有效促进中国出口产品质量升级。
This paper constructs a theoretical framework that describes the mechanism of the effect of total trade cost on the quality of export products,based on the research of Hallk&Sivadasan(2013)and Medin(2003).It uses the threshold model to reveal the actual mechanism of the effect of total trade costs on the quality of export products from the perspective of overall and multidimensional heterogeneity.The results are as follows.Firstly,the mechanism of the effect of total trade cost on the quality of export products shows a significant nonlinearity.This nonlinearity not only exists in the theoretical analysis framework,but also at the overall level and regional,geographical heterogeneity level.Secondly,the total trade cost has a“profit-erosion negative effect”on the quality of export products,and there is also a“forced innovative positive effect”.However,this forced positive effect has a certain“ceiling”.And the increase in total trade costs will significantly reduce the quality of export products after crossing the“ceiling”.Finally,the increase is relatively limited,despite the improved quality of China’s export products during 2002-2015.It will be effective to upgrade the quality of export products through further trade facilitation,larger industrial scale and more efficient total factor productivity.
