2012 Abstract: Although over the last decades many studies have been conducted to examine the impact of Capital Structure on Firm’s Performance, but the report results are mixed and the question of capital structure’s impact on performance still holds well and empirical study continues, especially in an emergency market like Vietnam where the financial imbalance occurs in almost business To answer this question, this study examines the impact of capital structure on corporate performance in Ho Chi Minh stock exchange, in which we control the effect of firm’s size, firm’s age, industrial sectors and ownership in the period 2007-2011 At first the research results show that Vietnamese firms are using an unbalance financial leverage with a big amount of debt while state controlled use more debt than non state controlled firm and heavy industry uses more debt than light industry and the difference is significant These results are consistent with theories An unbalanced panel of 97 companies are studied in this paper and report that a firm’s capital structure was found to have a significant and negative impact on the firm’s performance measures in the accounting measures and negative but insignificant in the market measure – Tobin’s Q Therefore, it is recommended that Vietnamese firms can reduce their debt ratio in order to increase profitability Control variables: Firm’s age, size, industrial, ownership show mixed results of relationship with firm’s performance, it may significant or not but with the same trend as the theories Key works: Capital structure, Debt Ratio, Firm’s performance, ROE, ROA, Tobin’s Q, Gross Profit Margin, Firm’s Age, Firm’s Size, Owner-ship, Different Industries Statement of original authorship I declare that this research project is my own work It is submitted in partial fulfillment of the requirements for the degree of Master of Business at Institute School of Business, University of Economics It has not been submitted before for any degree or examination in any other University I further declare that I have obtained the necessary authorization and consent to carry out this research Acknowledgments First and most importantly, I would like to thank my family especially my beloved husband for their love, support and patience from the beginning of the course to the end I could not have made it without them Secondly I would like to express my all respects and appreciation to Ms Pham Thi Thu Tra my supervisor for her invaluable support, advice and instructions Having her as a supervisor greatly assisted in getting to this research done I would also like to thank Mr Nguyen Dinh Tho, who exerts every effort in guiding me as well as ISB students to implement research I would like to thank all my colleagues in VCSC, for supporting me in getting data for the research I also thank to my ISB classmate, for their kindly support and assistance during this last year Last but not least, I would thank management, the faculty and all the staff at ISB for what they have done to support me as well as my classmate during the course Ho Chi Minh City, January 1st, 2013 Nguyen Thi Hong Loan Table of Contents Abstract: Statement of original authorship Acknowledgments List of tables List of Figures: Abbreviations Introduction: 1.1 Research Background: 1.2 Research objective 10 1.3 Research questions 10 1.4 Outline of the report 10 Literature review 11 2.1 Vietnam Economic overview: 11 2.2 Theory about Capital structure and Firm’s Performance 13 2.2.1 Modigliani and Miller’s theory 13 2.2.2 Trade-off theory 13 2.2.3 Pecking order theory 14 2.2.4 The information asymmetry and signaling theory 15 2.3 The impact of firm’s characteristics 16 2.3.1 Firm’s Age 16 2.3.2 Firm Size 17 2.3.3 Ownership 17 2.3.4 Different industrial sectors 18 2.4 Empirical evidences 19 2.5 Hypotheses development: 21 Research methodology 21 3.1 Data collection: 21 3.2 Variable of research: 22 3.2.1 Capital Structure (Independence Variable) 22 3.2.2 Firm’s performance (Dependence variable) 22 3.2.3 Control variable: 24 3.3 Regression Method 24 3.4 Model of study 25 3.5 Conceptual framework 26 Results and Discussions 27 4.1 Descriptive Statistics 27 4.2 Regression 32 Conclusions: 34 5.1 Conclusions: 34 5.2 Implication 35 5.3 Limitations and recommendations 35 Bibliography 37 Appendix 40 Appendix A: Final sample selection 40 Appendix B: DR -

As my knowledge, only several such studies have dealt in Vietnam Of these, San (2002) focused on a single industry sector (tourism) in a single locality (ThuaThien Hue Province), whilst Nguyen and Ramachandran (2006) focused on small and medium-size enterprises (SMEs) only By contrast, Vu (2003) analyzed companies listed the main stock exchange Although they are far less numerous than unlisted companies (most of the latter are SMEs), listed companies account for a larger share of economic activity Therefore, it is important to explore the relationship between capital structure and firm performance in Vietnamese market Corporation Danang Rubber Joint Stock Company Do Thanh Technology Corporation Sao Ta Foods Joint Stock Company Sai Gon Garment Manufacturing Trade Joint 18 19 20 DRC DTT FMC 21 GMC 22 23 IFS IMP 24 LBM 25 NAV 26 PAC 27 RAL 28 SCD 29 TAC Dry Cell and Storage Battery Joint Stock Company Rangdong Light Source and Vacuum Flask Joint Stock Company Chuong Duong Beverages Joint Stock Company Tuong An Vegetable Oil Joint Stock Company 30 TCR Taicera Enterprise Company 31 TTP 32 33 34 35 36 VIS VPK VTB ACL ANV 37 DPM 38 FBT Stock Company Interfood Shareholding Company Imexpharm Corporation Lam Dong Mineral and Building Material Jo Stock Company Nam Viet Joint Stock Company Tan Tien Plastic Packaging Joint Stock Company Viet Nam – Italy Steel Joint Stock Company Vegetable Oil Packing Joint Stock Company Viettronics Tan Binh Joint Stock Company Cuu Long Fish Joint Stock Company Nam Viet corporation Petrovietnam Fertilizer And Chemicals Corporation BenTre Forestry and Aquaproduct Import int Tires Specialty Chemicals Farming & Fishing 2006 2006 2006 1993 1994 1996 Clothing & Accessories Food Products Pharmaceuticals Building Materials & Fixtures Building Materials & Fixtures Electrical Components & Equipment Electrical Components & Equipment 2006 1993 2006 2006 1991 1983 2006 1994 2006 1963 2006 1976 2006 1961 Soft Drinks 2006 1952 Food Products Building Materials & Fixtures 2006 1975 2006 1994 Containers & Packaging 2006 1966 Steel Containers & Packaging Consumer Electronics Farming & Fishing Farming & Fishing 2006 2006 2006 2007 2007 2003 2006 1973 2003 1993 Specialty Chemicals 2007 2004 Farming & Fishing 2007 1994 Export Joint Stock Company Thuan An Wood Processing Joint Stock Company Hoa Phat Group Joint Stock Company General Materials Biochemistry Fertilizer Joint Stock Company 39 GTA 40 HPG 41 HSI 42 HT1 Ha Tien Cement Joint Stock Company 43 44 45 46 ICF L10 LSS MPC 47 TCM 48 49 TPC VHC 50 DCL Investment Commerce Fisheries Corporation Lilama 10 Joint Stock Company Lam Son Sugar Joint Stock Corporation Minh Phu Seafood Group Corporation Thanh Cong Textile Garment Investment Trading Joint Stock Company Tan Dai Hung Plastic Joint Stock Company Vinh Hoan Corporation Cuu Long Pharmaceutical Joint Stock Corporation 51 DQC Dien Quang Joint Stock Company 52 53 54 55 56 57 58 HLA HSG KMR OPC SBT TRA TTF Huu Lien Asia Corporation Hoa sen Group Mirae Joint Stock Company OPC Pharmaceutical Joint-Stock Company Société De Bourbon Tay Ninh Traphaco Joint Stock Company Truong Thanh Furniture Corporation 59 VHG Viet -
