全球价值链嵌入与我国制造业技术含量提升

本文利用世界投入产出数据库（WIOD）的数据，分别测算了中国制造业总体及16个细分行业的全球价值链嵌入程度以及国内技术含量，并实证分析了全球价值链嵌入对国内技术含量的影响。研究发现，全球价值链嵌入能够有效促进国内技术含量提升，并且全球价值链嵌入与国内技术含量存在非线性的倒U型关系。全球价值链嵌入通过中间产品效应、行业竞争效应以及大市场效应促进国内技术含量的提升。国内自主研发和国外技术引进都可以促进国内技术含量的提升，但国内自主研发对国内技术含量的作用要大于国外技术引进。从行业异质性来看，全球价值链嵌入对劳动密集型行业的促进作用要大于资本技术密集型行业以及高技术行业。

Global value chain embedding and promotion of technological content of Chinese manufacturing industry

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.
