摘要基于WIOD数据库和经适度修正的Hausmann等(2007)模型,本文从跨国层面测度了中间品进口技术含量和制造业产品国内增加值率,进而借助OLS、2SLS和联立方程等方法就前者对后者作用机制进行了细致分析。研究发现:(1)中国中间品进口技术含量明显高于自身比较优势水平,这既表明中国制造业最终品出口技术含量偏高很大程度上得益于超高技术含量中间品的进口,也表明未剔除"统计假象"条件下分析中国最终品技术含量,所得结论可能会存在一定偏误;(2)中间品进口技术含量对制造业国内增加值率的作用机制呈现倒U型,中技术含量中间品进口对产品国内增加值率产生的边际促进作用最大,进口过高技术含量中间品可能会对国内增加值率产生不利影响;(3)中间品进口技术含量对国内增加值率的倒U型作用机制非常稳固,经济增速冲击、税赋冲击、中间品进口冲击和滞后1-6期的时间动态冲击均无法撼动该机制。 Based on the WIOD database and the revised Hausmann et al.(2007)model,this paper measured the imported technology content of intermediate goods and the domestic value-added rate of the manufacturing industry,and analyzed the effect of the former on the latter by using OLS,2 SLS and Simultaneous-Equations.The main conclusions are as follows:Firstly,China’s imported technology content of intermediate goods is significantly higher than its own level of comparative advantage,which indicates that the high export technology content of China’s final products is largely due to the high imported technology content of intermediate goods,and that the analysis of the technology content of China’s final products without eliminating the"statistical illusion"may lead to errors;Secondly,the effect of the imported technology content of intermediate goods on the domestic value-added rate of manufacturing industry presents an inverted U-shape.Intermediate goods with medium imported technology content has the greatest marginal promotion effect on the domestic value-added rate of products,while intermediate goods with high imported technology content may have adverse effects on the domestic value-added rate of products;Thirdly,the inverted U-shaped mechanism is very stable,as economic growth shocks,tax shocks,intermediate goods import shocks and 1-6 periods lag dynamic shocks cannot shake the mechanism.
