摘要
本文选取2003~2018年中国30个省份的面板数据,构建双重中介效应模型对人工智能影响制造业优化升级的效果进行实证检验。研究发现:人工智能对制造业合理化和制造业高级化均具有明显的促进作用;行业异质性检验表明,人工智能对劳动密集型和技术密集型制造业的影响显著为正,对资本密集型制造业的影响为负;区域异质性检验表明,相较于中西部地区而言,人工智能对东部地区制造业升级的促进效果更为突出;进一步的影响机制检验表明,人工智能通过技术创新效应和人力资本积累效应推动制造业优化升级。因此,应强化人工智能在制造业中的应用,重视行业差异与区域异质性,有效提升技术创新和人力资本的中介作用,进而加快中国制造业优化升级。
This paper selects panel data of 30 provinces in China from 2003 to 2018,and a dual mediating effect model is constructed to empirically test the effect of artificial intelligence(AI)on optimization and upgrading of manufacturing industry.The research finds that AI plays a significantly positive role in promoting the rationalization and upgrading of manufacturing industry.Industry heterogeneity test shows that Al has a significantly positive impact on labour-intensive manufacturing industry and technology-intensive manufacturing industry,but a negative impact on capital-intensive manufacturing industry.Regional heterogeneity test shows that compared with the central and western regions,AI has a more prominent promotion effect on manufacturing upgrading in the eastern region.Further mechanism test shows that AI can promote the optimization and upgrading of manufacturing industry through the effects of technological innovation and human capital accumulation.Therefore,it is necessary to strengthen the application of AI in the manufacturing industry,to pay attention to industrial differences and regional heterogeneity,to effectively enhance the intermediary role of technological innovation and human capital,so as to optimize and upgrade the manufacturing industry.
