The objective of this paper is to assess the impact of supply chain quality integration on green supply chain management, environment performance and financial performance. The data was analyzed on 568 Vietnamese tourism businesses. Results were analyzed using SPSS 22 and Smart PLS 3.6 software. The results show that supply chain quality integration had a positive impact on green supply chain management and financial performance. Green supply chain management also had a positive impact on environment performance and financial performance. Green supply chain management also played a full mediating role in the relationship between supply chain quality integration and financial performance. However, neither size nor institutional pressure played any moderating role in the relationship between green supply chain management and financial performance and environment performance.

The objective of this paper is to assess the impact of transactional leadership on supply chain quality management and performance in tourism and travel enterprises in Vietnam. The analysis results were conducted on 298 typical tourism and travel enterprises in Vietnam in 2019. The testing results of the hypotheses show that transactional leadership had a positive impact on supply chain quality management and performance. At the same time, supply chain quality management did not play any full mediate role in the relationship between transactional leadership and performance. However, the qualification level had a statistically significant moderate role in the relationship between transactional leadership and performance. With the more highly qualified leaders, the more transactional leadership is applied, the higher the business performance for tourism and travel enterprises in Vietnam.
