Study of factors affecting the decision to study for a doctoral degree in the Doctor of Business Administration program in Logistics and Supply Chain Management

Abstract

This study investigates the factors influencing the decision to pursue a doctoral degree in the Doctor of Business Administration (DBA) program specializing in Logistics and Supply Chain Management at Suan Sunandha Rajabhat University. A mixed methods research design was employed. Quantitative data were collected through questionnaires from 100 prospective and current doctoral students, while qualitative data were obtained from in-depth interviews with 12 key informants, including faculty members, graduate students, and professionals in logistics-related fields. Quantitative data were analyzed using descriptive statistics and multiple regression analysis, whereas qualitative data were examined through thematic analysis. The results reveal that personal motivation and curriculum flexibility have a significant positive influence on doctoral study decisions (p < 0.05), while tuition cost has a significant negative effect. Institutional reputation and faculty quality also contribute to decision-making, though to a lesser extent. Additionally, differences in motivation were observed across age and income groups, indicating the role of demographic characteristics in educational decision-making. The qualitative findings support the quantitative results by highlighting the importance of flexible learning formats, research support, and career advancement opportunities for working professionals. This study contributes empirical evidence to doctoral education decision-making in logistics and supply chain management and offers practical implications for the design and management of DBA programs to enhance accessibility and attractiveness for prospective students.
