【摘要】:制造业出口国内外附加值测算是科学评估一个国家在全球价值链中的贸易利益的关键难题。传统的HIY方法因高估了出口国内附加值而与实际不符,Koopman测算方法对此虽有改进,但在信息不完全条件下由于无法利用传统的I/O矩阵以及直接投入系数矩阵而使其应用有所局限。本文通过构建GAMS模型解决了上述问题,并利用改进后的模型测算了2002—2012年中国出口国内外附加值的变化情况。结果表明:HIY方法忽略了加工贸易出口,因而高估了中国出口国内附加值率。由于加工贸易出口中使用了更多的进口中间投入品,本文的测算结果纠正了HIY方法在国外附加值率以及趋势方面的预测偏误。进一步研究出口国内附加值的相关影响因素发现,加工贸易出口和混合贸易的国内附加值极易受到国际资本流入的影响。由此可见,改进的附加值测算方法的确纠正了一直以来中国附加值测算偏误的问题。未来应该通过加快非加工贸易出口的发展,引进高端服务贸易,利用好本土企业出口与外资企业的关系,从而改善对外贸易依存度,提高中国制造企业在全球价值链中的贸易地位。
[Abstract]:The measurement of domestic and foreign added value of manufacturing exports is a key problem to evaluate a country's trade interests in the global value chain. The traditional HIY method is inconsistent with the reality because it overestimates the domestic added value of export. Although the Koopman calculation method is improved, its application is limited because it can not make use of the traditional I 鈮,
