Assessing the importance of transformational leadership competencies and supply chain learning to green innovation: Construction practitioners' perspectives

Purpose: This study aims to assess the importance of transformational leadership competencies, as well as supply chain learning, to green innovation in construction at the supply chain level. Design/methodology/approach: A questionnaire survey is conducted to collect data from construction firms in Vietnam. Many statistical analysis methods – including the Shapiro-Wilk test, one-sample Wilcoxon signed-rank test and Kruskal-Wallis test – are performed to achieve the research objectives. Findings: The results indicate that the importance of most transformational leadership competencies is similarly perceived among different role groups (i.e. directors/deputy directors, project managers, consultants, quantity surveyors and designers). Research limitations/implications: This study enriches the understanding of leadership research in construction at the supply chain level and also develops a theoretical framework for theory testing research, where the relationships of transformational leadership competencies and supply chain learning with green innovation are highlighted. Originality/value: Research on leadership in the green supply chain context is still limited, especially in the construction industry. Thus, this study is conducted to fill this gap of research.
