In the context of China's "digital power" strategy, the realization of a green and low-carbon shift in manufacturing has become a necessary condition to promote the economy, and the digital factor has increasingly become a new driving force. The text mining and IPCC methods were used to measure manufacturing enterprise digitalization and the level of enterprise carbon emission intensity from 2011 to 2021, respectively. This study then explored the impact of digitalization on manufacturing enterprise carbon emission intensity based on the least squares method model and instrumental variable method model. This research comes to three conclusions. (1) Digitalization can significantly reduce the enterprise carbon emission intensity of China's manufacturing industry, and the influence shows a "marginal increase." (2) Notably, a mechanism analysis indicates the intermediary effect sizes of four crucial intermediaries: green technology innovation > financing constraint > information asymmetry > energy use efficiency. Interestingly, digital information resources positively moderate the positive effect of digitalization on carbon emission intensity through three paths: financing constraints, green technology innovation, and information asymmetry. (3) The influence shows evident signs of heterogeneity-as environmental regulation, financial development, executive education, and R&D quality advance, the inhibiting effect of digitalization on enterprise carbon emission intensity becomes more pronounced. Finally, corresponding policy suggestions are proposed.
在中国“数字动力”战略背景下，实现制造业绿色低碳转型成为推动经济发展的必要条件，数字因素日益成为新的驱动力。本文运用文本挖掘和 IPCC 方法，分别测算了 2011—2021 年中国制造业企业数字化水平和企业碳排放强度，并基于最小二乘法模型和工具变量法模型，实证检验了数字化对制造业企业碳排强度的影响。研究得出以下结论：（1）数字化能够显著降低中国制造业企业碳排强度，且影响呈现“边际递增”特征；（2）机制分析表明，绿色技术创新、融资约束、信息不对称和能源利用效率 4 个中介变量在数字化影响制造业企业碳排强度中发挥了部分中介效应，数字化通过缓解融资约束、促进绿色技术创新和降低信息不对称程度正向影响企业碳排强度，而数字信息资源在这一过程中起到了积极的调节作用；（3）影响存在异质性，随着环境规制、金融发展、高管教育和研发质量的提升，数字化对企业碳排强度的抑制作用更加显著。最后，提出了相应的政策建议。
