戰略聯盟在永續供應鏈管理 (SSCM) 中的重要性日益增加。然而聯盟組合，作為聯盟的新興概念，卻在 SSCM 環境中大大的被忽略。 出於這個原因，本研究利用分類-加工模型 (CEM) 建立多層模型探索聯盟組合多元性對 SSCM 績效的影響（以經濟、環境和社會方面探討）。 除此之外，還驗證了永續合作的中介作用。 本研究收集了 321 家越南製造商的現場數據，並以驗證性因素分析評估了量表的準確性，而提出的模型和假設通過分層線性回歸來進行檢驗。 結果證實了聯盟投資組合多元性面向對永續合作的曲線和線性的影響，這反過來又提高了 SSCM 的性能。 通過將 CEM 作為新的理論背景引入供應鏈領域，本研究調查了聯盟投資組合多元性對 SSCM 績效影響中被忽視的動態機制。;The strategic alliance has been increasingly discussed in sustainable supply chain management (SSCM). However, an emerging and more vital concept of the alliance, namely alliance portfolio, is mainly ignored in the SSCM context. For that reason, this research draws on the categorisation-elaboration model (CEM) to develop a multi-layer model with the purpose of exploring the influence of alliance portfolio diversity on SSCM performance (from economic, environmental, and social aspects). In addition to that, the mediating effect of sustainability collaboration is also tested. The field data with 321 Vietnamese manufacturers as the respondents are collected. The confirmatory factor analysis method is applied to assess scale accuracy, while the proposed model and hypotheses are evaluated through hierarchical linear regressions. The curvilinear and linear effect of alliance portfolio diversity facets on sustainability collaboration, which in turn enhances SSCM performance, is confirmed. By introducing CEM as a new theoretical background to the supply chain domain, this research investigates the ignored dynamic mechanisms of the effects of alliance portfolio diversity on SSCM performance.
