中文摘要
Leveraging positions in industrial-chain networks to foster innovation growth is an important pathway for enhancing scientific and technological innovation capacity under open-economy conditions and for leading high-quality economic development. Using data from the OECD Inter-Country Input-Output Tables for 2000–2020, this paper measures the CheiRank and PageRank centrality of the global industrial-chain network and investigates the effects and mechanisms of positions in this network on innovation by Chinese firms. The results show that centrality in the global industrial-chain network has a significant innovation-driving effect: both CheiRank-based supply-chain position and PageRank-based demand-chain position promote innovation by Chinese firms. Mechanism tests indicate that centrality in global industrial chains promotes firm innovation through closed-triangle transmission effects, market-power expansion effects, and international technology-capture effects. Moreover, the positive effect of positions in the global industrial-chain network on firm innovation is stronger when the topological distance between industrial-chain nodes is shorter and transmission efficiency is higher. From a complex-network perspective, this paper provides new theoretical insights and empirical evidence for promoting the great circulation of industrial chains and achieving high-level self-reliance and strength in science and technology.
Abstract
产业链网络地位赋能创新增长是在开放条件下促进科技创新能力提升，引领经济高质量发展的重要路径。本文基于2000-2020年OECD国家间投入产出表数据，测度了全球产业链网络的CheiRank和PageRank中心度，探究了全球产业链网络地位对中国企业创新的影响及作用机制。研究发现，全球产业链网络中心地位具有显著的创新驱动效应，CheiRank供应链地位和PageRank需求链地位均能促进中国企业创新。机制检验结果表明，全球产业链中心地位通过闭合三角传递效应、市场势力扩张效应以及国际技术捕获效应促进企业创新。此外，当产业链节点的拓扑距离更近、传输效率更高时，全球产业链网络地位对企业创新的促进作用更强。本文从复杂网络视角为推动产业链大循环，实现高水平科技自立自强，提供了新的理论参考和经验证据。
