数字技术对制造业价值链升级机理的实证研究

Empirical Research on the Upgrading Mechanism of the Manufacturing Value Chain by Digital Technology

当前“双循环”新发展格局下,数字技术已成为制造业价值链升级的核心动力。对数字技术发展水平予以定量识别,结合省级面板数据,实证检验了数字技术发展在制造业价值链升级中的驱动作用。研究发现:数字技术发展可以推动制造业价值链地位升级,且对技术创新、消费需求和交易成本有显著性影响;在影响机制方面,数字技术发展主要通过技术创新效应、消费需求效应和交易成本变化效应间接促进制造业价值链升级。研究表明,大力发展、推广及应用数字技术有助于促进制造业价值链升级。为此,政府及企业应加快数字技术与传统制造业融合,积极构建创新驱动、消费拉动、交易成本优化的现代化制造业新生态。

Under the current new development pattern of"dual circulation",digital technology has become the core driving force for the upgrading of the manufacturing industry value chain.The development level of digital technology was quantitatively identified.Combined with provincial panel data,the driving role of digital technology development in the upgrading of the manufacturing industry value chain was empirically tested.The study found that the development of digital technology can promote the upgrading of the status of the manufacturing industry value chain and has a significant impact on technological innovation,consumer demand and transaction costs.In terms of the influencing mechanism,the development of digital technology mainly indirectly promotes the upgrading of the manufacturing industry value chain through the effects of technological innovation,consumer demand and changes in transaction costs.The research shows that vigorously developing,promoting and applying digital technology is conducive to promoting the upgrading of the manufacturing industry value chain.To this end,the government and enterprises should accelerate the integration of digital technology and traditional manufacturing industries,and actively build a new modern manufacturing ecosystem driven by innovation,driven by consumption and optimized by transaction costs.
