Abstract: Using the data of World Input-output database, this paper calculates the embedding degree of global value chain（GVC）as well as domestic technological content of Chinese manufacturing industry from 2001 to 2014. We further empirically study the effects of global value chain embedding、indigenous R&D、technology import and other influencing factors on the domestic technological content. The results show that GVC embedding can effectively promote the domestic technological content. And there exists significant non-linear inverted U shape relationship between GVC embedding and domestic technological content. GVC embedding can improve the domestic technological content through the intermediate import effect, the industry competition effect as well as the big market effect. Indigenous R&D and foreign technology import has positive promotion to domestic technological content, the promoting effect of indigenous R&D is greater. From the perspective of industry heterogeneity, we classifies manufacturing industry into three types: labor-intensive industries、capital and technology- intensive industries as well as high-tech industries. The promoting effect of GVC embedding is greater in labor-intensive industries than the other two industries.
