First and foremost, I am sincerely acknowledging the managing boards of Industrial
University of Ho Chi Minh City (IUH) and University of Economics Ho Chi Minh
City (UEH) for offering me the chance of studying PhD and financially supporting
my study.
I would like to thank my supervisor, Assoc. Prof. TRAN HA MINH QUAN makes

invaluable suggestions, and deep research insights have immensely shaped this study.
This dissertation would never have been written without their kind and patient
assistance.
I am also very grateful to Assoc. Prof. NGO VIET LIEM for his help with the
valuable comments, suggestions, and ideas.
