thesis is like taking a long journey, which requires a lot of time and effort During this journey, sometimes we feel lost, exhausted and want to give up, and to get to the destination we truly need guidance, cheers, encouragement and motivation from instructors, families, friends, and even passers-by Looking back at this journey, I would like to extend my heartfelt appreciation to many people who have wholeheartedly cheered me on and guided me through First and foremost, I would like to express my deepest gratitude to my supervisor, Professor Nguyen Trong Hoai, who was always available to answer any questions of mine and helped me stay focused on the research Extremely busy, he never failed to answer my calls or send me a text back His knowledge, patience and encouragement were the emotional and intellectual fuel that I needed to stand up and step forward whenever I felt discouraged and wanted to stop halfway I would also like to extend my most sincere thanks to Dr Tran Tien Khai, Dr Pham Khanh Nam, Dr Pham Hoang Van, and Dr Truong Dang Thuy for their valuable suggestions and comments on my TRD, which kept me from straying away from “the main road” Without their support, I could never reach the finish line of this journey My special thanks also go to all the VNP teachers and support staff Not only did they assist me with my study and thesis drafting process, they also made me truly feel to be a part of this wonderful community, to relive a beautiful and unforgettable college life I wish to thank, from the bottom of my heart, my wonderful classmates: Khanh Vu, for guiding me through the complicated Vietnam Enterprise Survey and Stata techniques, friends from my mini-group: Thien, Nhung, Hung, Ly, Viet for constantly reminding me of not giving up so that we can proudly celebrate together as VNPers, and other classmates for co-building a warm and bright C19 family Finally, I thank you my family, my husband and my little son for their unconditional love and support I always hope I can make them proud ABBREVIATIONS ADB : The Asian Development Bank AEC : The ASEAN Economic Community ASEAN-6 : Brunei, Indonesia, Malaysia, the Philippines, Singapore,

of manufacturing enterprises across 63 provinces by utilizing a unique dataset which includes the 2007-2012 Provincial Competitiveness Index merged with a set of data on firm-level performance extracted from the annual Vietnam Enterprise Survey The results show that provincial competitiveness significantly and economically explains the performance of firms located in different provinces Out of the nine subsets of institutional reforms, at least four sub-indices significantly and positively associate with the economic performance of the firms observed, which are Labor and Training, Legal Institutions, Transparency and Business Support Services Keywords: provincial competitiveness index, firm performance, labor productivity, ROA, ROE TABLE OF CONTENTS DECLARATION ACKNOWLEDGMENTS
