产品内国际分工与发展中国家的价值链提升

International Intra-product Specialization and Developing Countries’ Upgrading Value Chain

对40个发展中国家的实证研究发现,产品内国际分工对于价值链提升具有显著的推动作用,但主要来源于高层次分工合作的贡献,并且这一作用的发挥要以人力资本、服务质量以及制度环境等支持性条件的满足为前提。中国在参与产品内国际分工的过程中,价值链位置得到较大幅度的提升,交通服务质量的改进和偏向于高层次分工的政策引导起到关键作用,在人力资本和制度环境上还有进一步改善的潜力。

Based on an empirical study on forty developing countries, we find that international intra-product specialization has a significant positive effect on upgrading value chain. However, such effect is mainly from the contribution of high-level cooperation and needs to meet some preconditions such as human capital, service and institution. In the course of joining into intra-product specialization, China has upgraded value chain obviously. Improvements on transport services and the policies focused on highlevel specialization play the important roles.
