全球价值链网络与制造业出口复杂度——基于增加值贸易的测度与分析

Global Value Chain Network and the Export Sophistication of Manufacturing-Measurement and Analysis Based on Value-added Trade

本文基于增加值贸易视角构建多层面的全球价值链网络,运用社会网络分析法刻画了制造业全球价值链网络与出口复杂度的演变趋势,并对二者之间的关系进行了理论分析与实证检验。研究结果表明:中国在制造业全球价值链网络中的中心性和联系强度攀升趋势明显,但网络异质性仍存在上升空间;网络中心性、联系强度和异质性对制造业出口复杂度具有显著提升作用,且该提升作用主要通过技术进步实现;参与全球价值链网络对高收入国家以及高技术制造业的出口复杂度提升作用更显著。本文的研究结论对优化制造业出口结构,推动中国制造业高质量发展具有一定的政策启示。

Based on the value-added trade perspective,this paper constructs a multilevel global value chain(GVC)network and applies social network analysis to describe the development trends in the GVC network and the export sophistication of manufacturing.It also conducts theoretical analysis and empirical tests of the relationship between them.The results indicate that China's manufacturing is undergoing a shift towards greater centrality and improved connectivity within the GVC network.Nevertheless,there is still potential for growth in terms of network heterogeneity.The centrality,connectivity,and heterogeneity of the GVC network have a significant impact on the export sophistication of manufacturing,primarily through technological progress.Participation in the GVC network has a more pronounced effect on the export sophistication of high-income countries and high-tech manufacturing sectors.The research conclusions of this paper provide policy implications for optimizing the export structure and promoting the high-quality development of China's manufacturing.
