Vietnam is one of the most popular tourist destinations in the Asia-Pacific region and its tourism industry has been growing unprecedentedly over the past few years. However, the Vietnamese tourism industry (VTI) is concerned with the weakness competitive factor. This paper aims to analyze Green Supply Chain Management Practice (GSCM) and its effect on the destination image of Vietnam as the way to improve the completeness. The paper seeks to examine internal environment management (IEM) practices; external environment (EE) and environmental regulation (ER), as possible drivers to GSCM practices and its destination image. The empirical analysis used data from 269 questionnaires which were valid for analysis, through applying the PLS- SEM method. The result of path analysis indicates that the path between internal environmental management and GSCM practice in the VTI was highly significant; internal environmental management (IEM) had a significant impact on the external environment and also had a significant impact on destination image in VTI. The external environment has also maintained a significant impact on the GSCM practices of the VTI and on destination image in VTI. There is also a positive relationship between GSCM and destination image in VTI. As a result, it can be concluded that all hypotheses are supported. This paper concludes with a discussion of the implications of the findings from the study for tourism managers.
