A thorough study of the spatial impact of the digital economy on low-carbon logistics efficiency would be greatly significant for Regional Comprehensive Economic Partnership (RCEP) countries to improve low-carbon logistics efficiency and achieve sustainable cooperation. This study constructs a theoretical framework from the perspective of spatial effects on the impact of the digital economy on low-carbon logistics efficiency in RCEP countries. The entropy method was used to measure the level of digital economic development. The super-efficiency SBM model was used to measure low-carbon logistics efficiency. Spatial feature analysis was conducted using kernel density estimation and Moran's index, followed by empirical analysis using spatial econometric models to examine the spatial impact of the digital economy on low-carbon logistics efficiency in RCEP countries. The results indicate that in RCEP countries, both low-carbon logistics efficiency and the level of digital economic development exhibit significant spatial positive correlation. Furthermore, the digital economy can promote low-carbon logistics efficiency in economically neighboring countries through spatial spillover effects. The improvement of domestic low-carbon logistics efficiency can also promote low-carbon logistics efficiency in neighboring countries. This conclusion was supported by endogeneity tests and a convergence analysis. Additionally, the mechanism analysis revealed that improving the level of green energy can enhance the spatial spillover effects of the digital economy and promote low-carbon logistics efficiency. Finally, countermeasures and suggestions was proposed to improve the low-carbon logistics efficiency of RCEP countries through the digital economy.
深入研究数字经济对低碳物流效率的空间影响，对于 RCEP 国家提高低碳物流效率和实现可持续合作具有重要意义。本研究从数字经济对 RCEP 国家低碳物流效率影响的空间效应视角构建理论框架，采用熵值法测度数字经济发展水平，运用超效率 SBM 模型测度低碳物流效率，利用核密度估计和 Moran's 指数进行空间特征分析，然后采用空间计量经济学模型进行实证分析，考察数字经济对 RCEP 国家低碳物流效率的空间影响。结果表明，在 RCEP 国家，低碳物流效率和数字经济发展水平均表现出显著的空间正相关性。此外，数字经济可以通过空间溢出效应促进经济邻接国家的低碳物流效率，国内低碳物流效率的提高也可以促进邻国的低碳物流效率。这一结论得到了内生性检验和收敛性分析的支持。此外，机制分析表明，提高绿色能源水平可以增强数字经济的空间溢出效应，促进低碳物流效率。最后，提出了通过数字经济提高 RCEP 国家低碳物流效率的对策建议。
