本研究利用生命周期评估（LCA）方法，重点采用基于过程的方法和混合方法，考察了废弃物部门内部以及废弃物与其他经济领域（能源、交通、水和通信）之间的排放相互依赖性。分析采用了EXIOBASE多区域投入产出数据库。应用统计相关性分析来识别排放驱动因素的共性和差异。结果表明，某些填埋废弃物类别（尤其是有机基材料）之间存在强相关性，塑料与木材之间也存在关联，这表明它们具有共同的分解或管理路径。跨部门相互作用中出现了中等相关性，特别是在废弃物、能源和交通之间，而在处理机制不同的过程中（如填埋与废水处理）则观察到弱相关性。在方法论上，本研究强调了高维数据集带来的挑战，包括多重共线性，这些因素限制了线性模型的有效性。这些发现凸显了部门间相互依赖的复杂性，以及对综合性和材料特定策略的需求。通过展示EXIOBASE等系统性工具如何捕捉这些联系，该研究为构建更稳健的排放模型和制定有针对性的减缓政策奠定了基础。研究结果有助于推进环境核算框架，同时为跨关联部门的减排规划提供实用见解。
英文摘要
This study examines emission interdependencies within the waste sector and between waste and other economic domains, energy, transport, water, and communications, using Life Cycle Assessment (LCA) methodologies with emphasis on process-based and hybrid approaches. The analysis employs the EXIOBASE multi-regional input-output database. Statistical correlation is applied to identify commonalities and divergences in emission drivers. Results indicate strong correlations among certain landfill waste streams, particularly organic-based materials, as well as links between plastics and wood, suggesting shared decomposition or management pathways. Moderate correlations appear in cross-sectoral interactions, especially between waste, energy, and transport, while weak correlations are observed in processes with distinct treatment mechanisms, such as landfill versus wastewater. Methodologically, the study highlights challenges posed by high-dimensional datasets, including multicollinearity, which limit the effectiveness of linear models. These findings underscore the complexity of sectoral interdependencies and the need for both integrated and material-specific strategies. By demonstrating how systemic tools like EXIOBASE can capture these linkages, the research provides a foundation for constructing more robust emission models and informing targeted mitigation policies. The results contribute to advancing environmental accounting frameworks while offering practical insights for emission reduction planning across interconnected sectors.
