6. Conclusion
This study investigated the interaction effect between SSCC and incentives as well as their effect on sustainability performance, using survey research on Thai food manufacturing companies. The literature and real-world business context were reviewed to develop the hypotheses, which were tested by conducting EFA and hierarchical regression analysis. Moreover, the simple effect equation, cluster analysis, and Mann-Whitney non-parametric tests were performed to provide further support for the results. A positive relationship between SSCC and two aspects of sustainability, namely, economic and social performance, was found. Furthermore, a higher level of incentives is associated with a positive relationship between SSCC and social performance, but not with economic and environmental performance. This finding means that collaboration and incentives should be encouraged among supply chain partners to improve economic and social performance.
In addition, the study revealed the challenges to sustainability performance faced by firms in an emerging economy supply chain, where there is limited recognition of the importance of environmental aspects and where governments do not provide incentives to enhance sustainability performance through collaborative efforts among supply chain partners.
