中间品创新促进全球价值链升级的路径研究

Research on the path of intermediate product innovation promoting the upgrading of global value chain

当前中间品创新影响全球价值链的理论研究尚不完善,文章尝试从中间投入品的自主创新这一新的视角,探究中间品创新与价值链升级的内在关系及路径。首先,构建创新相关理论机制,从专业化分工、市场竞争效应和产品差异化三方面讨论中间品创新与价值链升级之间的内在关系;然后,从不同要素密集度行业展开经验分析并探究其升级路径;最后,提出我国应降低对发达经济体中间产品的依赖,通过增强国内中间品的创新,建立完善的国内科技创新体系,进而实现价值链攀升。

The theoretical research on the influence of intermediate product innovation on global value chain is not yet perfect.This paper attempts to explore the internal relationship and path between intermediate product innovation and global value chain upgrading from the new perspective of independent innovation of intermediate inputs.Firstly,the theoretical mechanism of innovation is constructed,and the internal relationship between intermediate product innovation and value chain upgrading is discussed from three aspects:specialized division of labor,market competition effect and product differentiation.Then,it analyzes the industries with different factor intensity and exploring their upgrading paths.Finally,it is suggested that China should reduce its dependence on intermediate products in developed economies,strengthen the innovation of domestic intermediate products,establish a sound domestic scientific and technological innovation system,and then realize the global value chain climbing.
