This paper aims to investigate sustainable tourism supply chains by examining the roles of environmental management, social support, and financial performance of tourist destination agencies. By placing the mediating role of innovativeness, this study developed a theoretical framework to explore the antecedents of tourism supply chain management. This research was conducted in a national park in Central Sulawesi, Indonesia, with 176 samples from tourism business actors. By using purposive sampling method, data analysis was performed using Partial Least Square-Structural Equation Modeling (PLS-SEM). The results of the analysis show a positive and significant influence of environmental management, social support, and financial performance on managerial innovation. These variables in the next analysis are estimated as antecedents of sustainable supply chain management (SSCM) in tourism, indicating positive and significant effects resulting from the analysis. In particular, the analysis also raises the important role of managerial innovation in improving the performance of sustainable supply chain management (SSCM) in tourism. Empirically, these findings underscore that the greater capabilities of the tourism organization in consolidating organizational resources, organizational performance and social support is more likely to increase the sustainability of SCM.

To increase competitive advantage, any company needs to improve its supply chain management. The aim of this study is to define the relationships between supply chain capability, supply chain performance and marketing performance. Some of the retail stores are no longer operating. Tool of analysis is the partial least square that is suitable for small sample size. The result of PLSSmart 3.0 shows that the relationship between supply chain capability and supply chain performance is positive and significant. However, the relationship between supply chain performance and marketing performance is positive but non-significant. Direct relationship between supply chain capability and marketing performance appears to be positive and significant. Indirect relationship between supply chain capability and marketing performance through supply chain performance also appears to be non-significant. The study can be a reference for retail managers to increase the supply chain in their marketing performance. Some further research needs to add other variables to see a more concrete relationship between supply chain capability and marketing performance.
