GVC参与度对中国制造业出口国内附加值的影响研究

基于贸易增加值核算框架,使用2000年~2014年中国18个制造业的样本数据,应用广义最小二乘法实证检验了GVC参与度对出口国内附加值的影响效果。结果显示:参与GVC程度的加深会带动出口国内附加值的增长,进口中间品会降低出口国内附加值,但GVC参与度提高所引起的出口国内附加值增长幅度大于进口中间品所引起的下降幅度,出口国内附加值与GVC地位存在U型关系,行业生产效率的提升、产品国际竞争力的增强和加入WTO都显著提高了出口国内附加值,改变出口国内附加值的测度方法后,上述结果依然稳健。将制造业分为高、中级技术类别,高技术制造业有更强的附加值获取能力,中级技术制造业更多依赖高密集度的劳动投入分享附加值。

Study on the impact of GVC participation on the domestic value-addedin China’s manufacturing export

Based on the accounting framework of trade value-addedandusing sample data from 18 manufacturing industries in China from 2000 to 2014,this paper uses the generalized least squares method to empirically test the effect of GVC participation on domestic value-added in export.The results show that the deepening of participation in GVC will increase the growth of domestic value-added in export,that the import of intermediate products will reduce the domestic value-added in export,but the increase in domestic value-added in export caused by increased participation in GVC is greater than the decline caused by imports of intermediate goods,that there is a U-shaped relationship between the domestic value-added in export and the status of GVC,that the improvement of industrial production efficiency,the enhancement of international competitiveness of products and the accession to WTO have significantly increased the domestic value-added in export.After changing the measurement method of domestic value-added in export,the above results are still solid.The manufacturing industry is divided into advanced and intermediate technology categories.The high-tech manufacturing industry has a stronger ability to acquire added value,while the intermediate technology manufacturing industry depends more on high-intensity labor input to share added value.
