本文在分析嵌入全球价值链影响企业生产率机理的基础上,利用2000-2006年《中国海关进出口贸易数据库》和《中国工业企业数据库》的合并数据,从微观层面测算了企业嵌入全球价值链的程度,并实证检验了参与全球价值链对企业生产率的影响。研究结果显示:参与全球价值链有益于提高企业生产率,说明全球价值链嵌入的生产率效应显著存在。另外,通过对企业所有制、资本密集度、贸易方式以及产品多样性等异质性特征的考察发现,国有企业在全球价值链嵌入过程中的生产率效应最高,外资企业次之,民营企业最低;高资本密集度企业融入全球价值链的生产率效应要高于低资本密集度企业;一般贸易企业以及多元化的产品策略更有利于企业在参与全球价值链的过程中进一步提升企业生产率。
Based on the analysis of the mechanism of embedded global value chain affecting enterprise productivity, the paper uses the combined data of China Customs Import and Export Database and China Industrial Enterprise Database from 2000 to 2006 Extent, and empirically tested the impact of participation in global value chains on firm productivity. The results show that participation in GVC helps to improve the productivity of enterprises, indicating that the productivity effect embedded in the global value chain exists significantly. In addition, by examining heterogeneous characteristics such as enterprise ownership, capital intensity, trade patterns and product diversity, state-owned enterprises have the highest productivity effect in the global value chain embedding process, followed by foreign-funded enterprises and private-owned enterprises. The productivity effect of capital-intensive firms integrating into global value chains is higher than that of low-capital-intensive firms; general trading firms and diversified product strategies are more conducive to further enhancing their productivity in their participation in global value chains.
