产品内国际分工与中国制造业技术升级

International Intra-product Specialization and Technological Upgrading in Chinese Manufacturing

本文以中国的制造业部门作为研究对象,基于1995～2008年间的面板数据集,对产品内国际分工与生产率之间的关系进行实证分析,以检验这种新型国际分工模式是否产生了技术升级效应。研究发现,产品内国际分工从进口和出口两方面共同促进了生产率增长,但出口的贡献更大。分工的技术升级效应在近几年才开始显现且主要来源于零部件贸易。中间品出口通过熟练劳动力偏向的劳动要素配置效应以及其他途径间接推动技术进步,而中间品进口对技术升级的作用则更多地依赖投入引导效应和技术溢出效应。

Based on a panel dataset over the period 1995～2008,the paper carries out an empirical investigation on the relationship between international intra-product specialization and productivity in Chinese manufacturing.The findings suggest that international intra-product specialization has promoted productivity growth from the aspects of imports and exports,while exports have made greater contribution to such growth.The effects of international intra-product specialization on technological upgrading appear in recent years and mainly from trade in parts and components.Export of intermediates drives technological progress from the effect of skilled-biased labor factor distribution.But import of intermediates accelerates technological upgrading mainly depending on the effects of inputs channel and technology spillover.
