The objective of this study is to investigate the relationship between supply chain linkage and business performance in the lychee supply chain in Vietnam. The study collected 395 matched samples after sample screening. Partial least squares (PLS) algorithm is used to process the data. Research results show a link between supply chain linkage and business performance. Furthermore, research shows that risk supply chain, quality management, and business strategy also impact supply chain linkages and business performance.

The study aims to examine the impact of supply chain linkages on the performance of businesses. Quantitative research is used by implementing the analysis of the SEM linear structure model. A survey is conducted consisting of 598 samples - experienced managers who had the knowledge of the management of supply chain activities in enterprises in Vietnam. Research results show that supply chain linkages, although not having a direct impact, has an indirect impact on the business performance of enterprises through the intermediary factors of trust and business strategy and the opportunistic behaviors of the participating members. Also, research has demonstrated that opportunistic behaviors have negative effects on trust among members of the supply chain.

The objective of this paper is to assess the impact of supply chain linkage on the performance of aluminum profiles enterprises in Northern Vietnam. After qualitative research results, the research team has discovered a new variable in the linkage model which is the Policy linkage. The study performs official quantitative research on 289 aluminum profiles in Northern Vietnam and the results were analyzed on SPSS 22 and Smart PLS 3.0 software. The results indicate that the links in the supply chain include: Supply linkage, customer linkage, policy linkage and internal linkage all contribute significantly to supply chain management efficiency. Moreover, the supply chain management efficiency had a positive effect on business performance of aluminum profiles in the northern region of Vietnam. Finally, the study gives solutions and recommendations to help aluminum bar enterprises shape the northern region of Vietnam to better link in the supply chain and improve business performance.
