摘要
本文以我国智能制造示范项目为准自然实验,手工收集并整理了2015—2022年上市公司是否实施智能制造的年度数据,采用PSM-DID的研究方法,从企业绿色全要素生产率的研究视角考察了智能制造的实施效果。研究发现,智能制造能够显著提升企业的绿色全要素生产率。机制检验表明,该影响是通过促进企业绿色技术创新,优化人力资本结构两条渠道得以发挥。异质性检验发现,这种影响在企业的规模属性、产权属性、行业属性和地区属性中存在异质性。拓展性检验发现,智能制造的实施具有长期价值效应,能够提升企业当期及未来一期价值。
Based on China’s intelligent manufacturing demonstration project as the natural experiment,this paper manually collected and sorted out the annual data of whether listed companies implement intelligent manufacturing from 2015 to 2022,and investigated the implementation effect of intelligent manufacturing from the perspective of enterprise green total factor productivity.The study found that intelligent manufacturing can significantly improve the green total factor productivity of enterprises.The mechanism test shows that the influence can be exerted through two channels of promoting enterprises’green technology innovation and optimizing human capital structure.The heterogeneity test shows that the influence is heterogeneous among firm size attributes,property rights attributes,industry attributes and regional attributes.The expansion test found that the implementation of intelligent manufacturing has a long-term value effect,which can enhance the value of the enterprise in the current and future periods.
