贸易便利化对企业出口国内附加值率的影响——来自中国制造业企业的证据

Effects of Trade Facilitation on Domestic Value-added Ratio of Firms’ Export: Evidence from Chinese Manufacturing Firms

在构建贸易便利化影响企业附加值贸易的理论框架基础上,文章采用中国制造业企业微观数据,实证检验了贸易便利化对企业出口国内附加值率(DVAR)的影响及其作用机制。研究发现:无论是采用贸易便利化综合指数,还是贸易便利化分领域指标,推进贸易便利化会显著提高企业出口DVAR。同时,相对于中西部企业、中低技术行业企业和本土企业而言,贸易便利化对东部企业、高技术行业企业和外资企业出口DVAR的促进作用更大。进一步机制检验发现,贸易便利化的相对价格渠道降低了企业出口DVAR,但通过成本加成渠道提高了企业出口DVAR,贸易便利化总体上对企业出口DVAR的净效应为正。上述结论意味着,推进贸易便利化改革对于提高企业出口DVAR和出口竞争力具有重要的现实意义。

Based on the theoretical framework of trade facilitation affecting the value-added trade of Chinese enterprises this paper uses the micro data of Chinese manufacturing enterprises to empirically test the impact and its transmission mechanism of trade facilitation on domestic value-added ratio (DVAR). The results show that with both the trade facilitation comprehensive index and trade facilitation subfield indicators, the promotion of trade facilitation significantly promote firms export DVAR. Meanwhile, trade facilitation has a greater role in promoting the export of DVAR in Eastern enterprises, high-tech enterprises and foreign-funded companies than in Midwestern, lower middle technology and native companies. Further tests on mechanisms show that, trade facilitation reduces firms export DVAR through relative price effect, but it significantly improves firms export DVAR through markup effect, and on the whole, the net effect of trade facilitation on firms export DVAR is positive. The above conclusions mean that promoting trade facilitation reform has important practical significance for improving enterprises DVAR and export competitiveness.
