数字化转型对制造业影响的实证研究OACHSSCD

To fulfill the strategic commitment to the"dual carbon"goals,promoting the digital upgrad-ing of the manufacturing sector has become a critical task.This study examines the relationship be-tween corporate digital transformation and carbon emissions,focusing on manufacturing companies listed on China's A-share market.Empirical analysis reveals that digital transformation significantly re-duces corporate carbon emissions,a conclusion that holds even after robustness tests.Further mecha-nism analysis indicates that digital transformation influences carbon emissions primarily through three distinct channels:technological innovation,production efficiency,and asset turnover.Specifically,technological innovation plays a positive role in reducing carbon emissions,as digital transformation helps companies cut emissions by increasing R&D investment;due to the rebound effect,digital trans-formation indirectly increases carbon emissions in the short term after improving production efficiency;and due to the scale expansion effect,digital transformation also indirectly increases carbon emissions after improving asset turnover.Formal environmental regulations and financing constraints play a mod-erating role in the relationship between the two and their impact pathways.At the same time,hetero-geneity tests indicate that the carbon reduction effects of digital transformation are more pronounced in state-owned enterprises,small enterprises,and low-labor-intensive enterprises.The findings of this study provide valuable theoretical foundations and practical references for enterprises in formulating digital transformation strategies,planning carbon reduction pathways,and refining relevant policies,thereby helping manufacturing enterprises better achieve digital sustainability.
