全球价值链嵌入与制造企业加成率

Embedded in GVCs and Markups of Chinese Manufacturing Firms

随着中国融入全球生产网络程度不断加深,贸易自由化形成的竞争效应与资源在不同生产率企业间优化配置,促使一国出口企业总体加成率水平得以提升,但与已有研究“低加成陷阱”结论相悖。本文采用微观企业层面数据,基于全球价值链参与的视角展开经验验证。研究结果表明:从整体上看,融入全球价值链有效提高了加成率,但两者存在“倒U型”关系,且不同企业类型具有异质性。进一步分析机制检验发现,技术溢出和目的地市场效应可以改善加成率,但成本节约效应作用有限且随嵌入程度加深会产生负向影响。

With the deepening of China’s integration into the global production network,the competitive effect of trade liberalization and the optimal allocation of resources among different productivity enterprises have promoted the overall markups of export enterprises in a country.However,it is contrary to the previous research.This paper uses Chinese firm-level data to verify from the perspective of GVCs embedding.The result shows that participation in GVCs has effectively increased markups on the whole,but there is an“inverted u-shaped”relationship between them,meanwhile the influence of different enterprise types is heterogeneous.Further analysis of the influence mechanism shows that enterprises’participation in GVC will improve markups through technology spillover effect and large market effect,but the cost saving effect will play a limited role and have a negative impact with further integration into GVCs.
