Valuing Social Capital: Shifting Strategies for Export Success of Vietnamese Small- and Medium-Sized Enterprises

Valuing Social Capital: Shifting Strategies for Export Success of Vietnamese Small- and Medium-Sized Enterprises Huong Thi Xuan NGUYEN Victoria Institute of Strategic Economic Studies Victoria University, Melbourne, Australia Submitted in fulfilment of the requirement of the degree of Doctor of Philosophy February 2018 ABSTRACT This study examines the impact of social capital on the export success of domestic SMEs in Vietnam, looking at both export propensity (whether they export at all) and export performance (how much they export) Two stylized facts inspire the research The first is the relatively modest performance of Vietnamese SMEs in export activities to date, despite their potential and increasing importance in the economy The second is the widespread perception within Vietnam about the power of social relationships of firms in the Vietnamese business environment This study uses a mixed methods approach, combining a qualitative thematic analysis of semi-structured interviews of SME owners/managers with quantitative testing of hypotheses on a secondary panel dataset from 2007 to 2015 Logistic regression models were employed to test hypotheses related to export propensity and multiple linear regressions were used to test those related to export performance The results indicate that social capital is positively related to export propensity of domestic SMEs, but that its impacts on their export performance are not consistent Each type of network impacts differently on export performance indicators of the studied SMEs (positive, negative and sometimes non-significant) Similarly, the qualitative study provides evidence that social capital supports SMEs in the initial stage of their export venture, but not their continuous export sustainability One of the significant findings to emerge from the qualitative study is that the impact channels of social capital on SMEs’ export success may have changed from relying on rent-seeking opportunities provided by close connections with authorities towards being a tool for improving credibility and building capability for SMEs This study highlights the importance of establishing an appropriate networking strategy for SMEs who wish to pursue export ventures It suggests that, if SMEs aim at long-term export success, they may need to diversify their networks, including business networks and social networks, both domestically and internationally, rather than focus on connections with politicians and authorities This is because the expected benefits from rent appropriation in export activities will eventually diminish as a more transparent system is put in place Hence, SMEs should utilize their networks to improve their knowledge, credibility and capability, which help in enhancing their long-term competitiveness The present study also implies that the government and relevant trade ii associations, in supporting SMEs to participate successfully in the international market, may need to focus on long-term network building and capacity-building activities iii PUBLICATIONS INTEGRATED IN THE THESIS Some sections of this thesis have been presented at a conference and

received tremendous support and continuous encouragement from many special people Hence, I would like to take this opportunity to sincerely express my gratitude to those who have assisted me in this most challenging yet rewarding journey I wish to firstly express my deepest gratitude to my principal supervisor, Professor Adam Fforde, for his dedicated supervision, invaluable guidance, detailed comments, practical suggestions, constructive feedback and most importantly his continuous encouragement Several times during my journey, when I lost my confidence, and my own belief almost failed to carry me, he lifted me up by his strong determination that my work does matter, and that academic scholarship should be a journey to extend one’s own limit This was one of the major empowerments for me to complete my thesis I especially wish to show my heartfelt thanks to my co-supervisor, Professor Peter Sheehan, for his scholarly advice, invaluable encouragement, and continuous feedback He has provided me with his generous assistance, always prepared to listen to my troubles He persuasively taught me the discipline of doing academic research I could not have asked for more supportive and considerate supervision My greatest appreciation also goes to the Australian Government, Department of Education and Training for granting me the Prime Minister’s Australia Asia Scholarship This prestigious scholarship has provided me with a wonderful opportunity to undertake my PhD study and to pursue my academic endeavour I am thankful for the generous financial sponsorship of the Endeavour Postgraduate Award and the dedicated support from the scholarship administrative team I would like to extend my appreciation to Dr Viet Le, Swinburne University, for his valuable input at the early stage of my research; to Dr Sidney Lung and Dr Masha Fridman of Victoria University for their statistics advice; and to Dr Bradley Smith for his meticulous and professional editing services, according to the university-endorsed ‘Guidelines for Thesis Editing’ I would like to send my sincere thanks to all the research participants, without whose voluntary participation this research would not have been possible My appreciation also goes to the Victoria Institute of Strategic Economic Studies, Victoria University for administrative and technical support throughout my research work vi I am indebted to the unconditional love and support of my parents, who instilled in me the eternal appreciation for knowledge and the attitude of trying and thriving This thesis would not have been completed without my parents’ strongest belief in my success Deep gratitude also goes to my parents-in-law and my siblings for their emotional support during my study away from home My sincerest thanks are extended to my friends and their families for helping me and my family in all aspects of our life in Australia, so that I can concentrate and complete my study Last but not least, I owe my loving thanks to my husband, Minh Hieu Tran, who made enormous sacrifices in his career to support my study in Australia I am fortunate to have the endless inspiration from my sweetest daughter, Linh Tran, who insists that I ‘read as a writer and write as a reader’ Her positive attitude, enjoyment and happiness help me fight the stress I also have an untold amount of empowerment from my cutest little son, Xuan Son Tran, who expresses curiosity about everything around him, including the question of when can mum become an alumnus of Victoria University I am wholeheartedly thankful to your love, your tolerance and your continuous encouragement during my journey vii TABLE OF CONTENTS ABSTRACT II DECLARATION OF AUTHENTICITY IV PUBLICATIONS INTEGRATED IN THE THESIS V ACKNOWLEDGEMENTS VI
