摘要
制造业数字化是数字技术与制造业融合发展的新型产业形态,为中国实现绿色低碳发展提供了新契机。文章基于2002-2018年投入产出表和制造业细分行业面板数据,系统考察了制造业数字化对碳生产率的影响效应及内在机制。实证结果表明:制造业数字化与碳生产率存在显著且稳健的正向影响关系,且该减排效果存在行业技术水平、数字要素的差异。机制研究发现,经济发展水平发挥正向调节效应,制造业数字化对碳生产率的影响基于优化能源结构、降低资本密集度两大中介渠道发挥作用。研究结论对推动低碳经济发展具有借鉴意义。
Manufacturing digitization is a new type of industrial form that integrates and develops digital technology and manufacturing industry,which provides a new opportunity for China to achieve green and low-carbon development.Based on the inputoutput tables and panel data of manufacturing industries from 2002 to 2018,the author systematically examines the effect and underlying mechanism of manufacturing digitization on carbon productivity.The empirical results show that there is a significant and robust positive relationship between manufacturing industry digitization and carbon productivity,with emission reduction effects varying across industry technological levels and digital elements.Mechanism research reveals that the level of economic development plays a positive moderating effect,and the impact of manufacturing industry digitalization on carbon productivity operates through two main intermediary channels:optimizing energy structures and reducing capital intensity.The findings of the study are useful for promoting the development of low-carbon economy.
