财政支持、源头创新与产业链安全

Financial Support,Source Innovation and Industrial Chain Security

强化源头创新是化解国外掣肘中国技术链、供应链以及产业链安全发展的根本办法。选取2003—2022年中国通信装备产业分布在30个省级行政区的面板数据,通过门槛效应回归模型和调节效应回归模型展开实证研究,探索政府财政支持背景下源头创新影响产业链安全的效果和机制。研究表明,相对于应用创新,源头创新对产业链安全发展的积极作用更强,且存在显著的一期滞后效应和单一门槛效应等基本结论。另外,研究还发现产业发展引导、科技项目支撑、创新平台搭建等政府财政支持方式可在源头创新影响产业链安全发展的过程中发挥正向调节效应。基于此,提出重塑政府与市场关系、拓宽财政支持渠道、优化创新资源配置等建议,以期从政府角度为提升源头创新能力、构筑安全产业链提供更多政策支撑。

Strengthening source innovation is the fundamental way to resolve foreign constraints on the secure development of China's technology chain,supply chain,and industrial chain.Select the panel data of China's communication equipment industry distributed in 30 provincial-level regions from 2003 to 2022,empirical research was conducted through threshold effect regression model and moderation effect regression model to explore the effect and mechanism of source innovation on industrial chain security under the background of government financial support.The basic conclusions were drawn that source innovation has a stronger effect on industrial chain security development than application innovation,and there are significant first stage lag effects and single threshold effects.In addition,the study also found that government financial support methods such as industry development guidance,technology project support,and innovation platform construction can play a positive moderating effect in the process of source innovation affecting industrial chain security development.Based on this,suggestions are proposed to reshape the relationship between the government and the market,broaden financial support channels,and optimize the allocation of innovative resources,in order to provide policy support from the government's perspective for enhancing source innovation capabilities and building a secure industrial chain.
