Construction industry has adopted reverse logistics (RL) concept to manage high volumes of demolition waste (DW). However, DW RL supply chains (RLSCs) were found to be suffering from uncertainties, information deficiencies, and uncoordinated material flows. Improving supply chain integration (SCI), specifically external integration, across DW RLSCs was identified as a possible solution to overcome such problems. Despite this, studies that focus on external integration in DW RLSCs are limited. Using a systematic literature review (SLR), this study explores external integration in DW RLSCs. Sixty-six articles from three databases published between 2006 and 2020 were subjected to descriptive and content analysis. Arrangement of material, information, and financial flows across DW RLSCs, inhibitors of external integration, and potential measures for improving external integration were analyzed. Accordingly, material, information, and financial flows across DW RLSCs were mapped, and inhibitors of external integration, along with potential measures for improving external integration were identified. As the key outcome of this SLR, these findings were developed into a conceptual framework, which shows the main factors that inhibit and improve external integration in DW RLSCs. The framework will be useful in guiding further empirical research and informing industry practice. Several future research directions are also proposed to expand knowledge around the research domain.

建筑业已采用逆向物流 (RL) 概念来管理大量拆迁废物 (DW)。然而，DW RL 供应链 (RLSC) 被发现存在不确定性、信息不足和不协调的物料流。改进跨 DW RLSC 的供应链集成 (SCI)，特别是外部集成，被确定为克服此类问题的可能解决方案。尽管如此，专注于 DW RLSCs 外部整合的研究是有限的。本研究使用系统文献综述 (SLR)，探讨了 DW RLSC 的外部整合。对 2006 年至 2020 年间发表的三个数据库中的 66 篇文章进行了描述性和内容分析。跨 DW RLSC 的材料、信息和资金流的安排，外部整合的抑制剂，并分析了改善外部整合的潜在措施。因此，对跨 DW RLSC 的材料、信息和资金流进行了映射，并确定了外部整合的阻碍因素，以及改善外部整合的潜在措施。作为该 SLR 的主要成果，这些发现被发展成一个概念框架，该框架显示了抑制和改善 DW RLSC 外部整合的主要因素。该框架将有助于指导进一步的实证研究和为行业实践提供信息。还提出了几个未来的研究方向，以扩展研究领域的知识。同时确定了改进外部整合的潜在措施。作为该 SLR 的主要成果，这些发现被发展成一个概念框架，该框架显示了抑制和改善 DW RLSC 外部整合的主要因素。该框架将有助于指导进一步的实证研究和为行业实践提供信息。还提出了几个未来的研究方向，以扩展研究领域的知识。同时确定了改进外部整合的潜在措施。作为该 SLR 的主要成果，这些发现被发展成一个概念框架，该框架显示了抑制和改善 DW RLSC 外部整合的主要因素。该框架将有助于指导进一步的实证研究和为行业实践提供信息。还提出了几个未来的研究方向，以扩展研究领域的知识。
