基于产品内分工的我国制造业价值链攀升:理论假设与实证分析

Value Chain Upgrading of China's Manufacturing Industry Based on Intra-Product Specialization: Theoretical Assumptions and Empirical Analysis

本文从产品内分工的视角构建理论模型,提出了影响我国制造业价值链攀升的三个假说命题。利用我国制造业24个行业的面板数据对假说命题进行了实证检验,结果表明:研发水平、人力资本和制度环境对所有类型制造业价值链攀升都具有显著的促进作用;产业规模对技术密集型和资本密集型制造业价值链攀升具有显著的促进作用,但对总体制造业和劳动密集型制造业影响不显著;外商直接投资对总体制造业和劳动密集型制造业价值链攀升具有显著的促进作用,但对技术密集型和资本密集型制造业影响不显著;国际分工参与程度除对劳动密集型制造业影响不显著外,对总体制造业及其他类型制造业都具有显著的促进作用。

This paper builds a theoretical model based on intra-product specialization, and proposes three hypotheses which influence the value chain upgrading of China＇s manufacturing industry. By using panel data of China＇s 24 manufacturing industries, this paper conducts empirical test on hypothesis proposition, and the results show that： the level of research and development, human capital, and institutional environment play significant roles in promoting the overall manufacturing sector; the scale of the industry plays a significant role in promoting technology-intensive and capital-intensive manufacturing value chain upgrading, but has no significant effect on overall manufacturing and labor-intensive manufacturing~ FDI plays a significant role in promoting the upgrading in overall manufacturing and labor-intensive manufacturing value chain, but has no significant impact on the technology-intensive and capital-intensive manufacturing; international division of labor participation plays a significant role in promoting overall manufacturing industry except labor-intensive manufacturing industry.
