数字经济在推动煤炭采选业向绿色低碳发展转型方面发挥着至关重要的作用。深入分析数字经济对煤炭采选业碳排放强度的影响机制,可为我国煤炭采选业低碳绿色发展提供路径。研究采用熵值法测算了2011—2022年中国25个省份数字经济发展指标,运用固定效应模型、中介效应模型及门槛效应模型探讨了数字经济对煤炭采选业碳排放强度的影响及其作用机制。研究结果表明:数字经济发展显著抑制煤炭采选业碳排放强度,该结论在剔除部分样本和内生性检验等多种稳健性检验后,依然稳定成立。与西部地区相比,数字经济对中东部地区煤炭采选业碳减排效应更为显著;与资源型地区相比,非资源型地区数字经济发展对煤炭采选业碳减排效果更为显著。在对外开放程度较高的地区,数字经济对煤炭采选业碳排放强度的抑制效果更为显著。科技创新和产业结构升级是数字经济实现煤炭采选业碳减排的两大重要路径。此次研究不仅丰富了数字经济与碳排放领域的理论与实证研究,在促进煤炭采选业绿色转型和实现碳减排目标方面也具有重要意义。

Digital economy plays a vital role in promoting the transformation of coal mining and selection industry to green and low-carbon development. In-depth analysis of the influence mechanism of digital economy on the carbon emission intensity of coal mining and selection industry can provide a path for the low-carbon and green development of China′s coal mining and selection industry. This study uses the entropy method to calculate the digital economy development indicators of 25 provinces in China from 2011 to 2022, and uses the fixed effect model, mediating effect model and threshold effect model to explore the impact of digital economy on the carbon emission intensity of coal mining and selection industry and its mechanism. The results show that the development of digital economy significantly inhibits the carbon emission intensity of coal mining and selection industry, and this conclusion is still stable after eliminating some samples and various robustness tests such as endogenous tests. Compared with the western regions, the effect of digital economy on carbon emission reduction of coal mining and selection industry in the central and eastern regions is more significant; Compared with resource-based regions, the development of digital economy in non-resource-based regions has a more significant effect on carbon emission reduction in coal mining and selection industries. In the regions with a higher degree of opening to the outside world, the inhibitory effect of digital economy on the carbon emission intensity of coal mining and selection industry is more significant. Scientific and technological innovation and industrial structure upgrading are two important paths for digital economy to achieve carbon emission reduction in coal mining and selection industry. This study not only enriches the theoretical and empirical research in the field of digital economy and carbon emissions, but also has great significance in promoting the green transformation of coal mining and selection industry and achieving carbon emission reduction targets.
