摘　　要：以804家战略性新兴产业上市公司2016-2020年数据为样本,构建双重差分(DID)模型进行实证检验。结果表明:首先,战略性新兴产业企业应用工业互联网技术能显著提高其盈利能力,这个结论在经历替换被解释变量、调整研究样本、PSM-DID回归等稳健性检验后依然成立;其次,工业互联网的这种赋能效应存在异质性:行业上表现为对新材料产业的赋能最强但对生物医药产业的赋能最弱,地区上表现为“中部最强、西部次之、东部较小、东北最弱”,企业属性上表现为对非国有企业赋能显著而对国有企业不显著;最后,工业互联网对战略性新兴产业企业盈利能力的影响主要通过全要素生产率提升效应及成本率降低效应来实现。This paper used the data of 804 listed companies in strategic emerging industries from 2016 to 2020 as a sample to construct a difference-in-difference(DID)model for empirical testing.The results showed that:firstly,the application of Industrial Internet technology by strategic emerging industry enterprises could significantly improve their profitability.This conclusion still holds after undergoing robustness tests such as replacing the explained variables,adjusting the research sam-ple,and PSM-DID regression.Secondly,there was heterogeneity in the Industrial Internet's enabling effect:industry-wise,it had the strongest empowerment for the new materials industry but the weakest for the biomedicine industry;regional-ly,it had“the strongest in the central,followed by the west,and smaller in the eastern,and weakest in the Northeast”;the enterprise attributes were significant in empowering non-state-owned enterprises but not significant in state-owned enter-prises.Finally,the impact of the Industrial Internet on the profitability of enterprises in strategic emerging industries is mainly through the total factor productivity improvement effect and cost rate reduction effect.
