数字经济对制造业“四链”融合的影响

The Impact of Digital Economy on the Integration of the“Four Chains”in Manufacturing Industry

数字经济对促进制造业创新链产业链资金链人才链(简称“四链”)融合,进而推动现代化产业体系建设具有重要意义。通过理论分析并基于2011—2021年中国制造业省级数据进行实证检验,探析数字经济对制造业“四链”融合的具体影响。研究结果表明,数字经济能够显著促进制造业“四链”融合,且在一系列稳健性检验之后结论依然成立。作用机制检验发现,缓解资本错配与劳动力错配是数字经济促进制造业“四链”融合的重要机制。空间计量检验结果表明,数字经济对促进制造业“四链”融合存在正向空间溢出效应。分组估计检验结果表明,在沿海地区与“一带一路”沿线地区,数字经济对促进制造业“四链”融合更具推动力。各地区应遵循“四链”融合内在逻辑,夯实制造业“四链”融合基础;推动数字经济高质量发展,畅通数字经济赋能渠道;以政策为导向,借鉴先进地区经验推进数字经济赋能制造业“四链”融合进程。

The digital economy is of profound significance in advancing the integration of innovation chain,industry chain,capital chain and talent chain(abbreviated as“four chains”)in manufacturing industry,and thus expediting the construction of the modern industrial system.Through theoretical analysis and an empirical test based on the provincial data of China’s manufacturing industry from 2011 to 2021,this paper explores the specific impact of digital economy on the“four chain”integration of manufacturing industry.The results of the benchmark regression test indicate that the digital economy can significantly promote the integration of the“four chains”in the manufacturing industry,and the conclusion still holds true after a series of robustness tests.The mechanism test indicates that alleviating capital mismatch and labor mismatch is an important mechanism for the digital economy to promote the integration of the“four chains”in the manufacturing industry.The results of the spatial econometric test indicate that the digital economy has a positive spatial spillover effect on promoting the integration of the“four chains”in the manufacturing industry.The results of the group estimation test show that in coastal areas and areas along the“the Belt and Road”route,the digital economy has more impetus to promote the“four chains”integration in the manufacturing industry.Each region should follow the inherent logic of the integration of the“four chains”and consolidate the foundation of the“four chains”integration of the manufacturing industry;they should promote high-quality development of the digital economy and smooth the channels for empowering the digital economy;they should be guided by policies and draw on the experience of advanced regions,so as to promote the integration of the“four chains”empowered by digital economy in the manufacturing industry.
