especially since the research of Modigliani & Miller (1985) Most businesses regardless of industry group want to keep the cost of capital to a minimum, and thereby maximize the value of their business because the cost of capital affects nearly all activities of the business, from the feasibility of projects or investments to business results and also the main load risks that businesses face Therefore, choosing an optimal capital structure between equity and debt is an art for financial managers The main objective of this study is to understand the impact of capital structure on the business performance of non-financial firms listed on Vietnamese stock exchanges and how these companies adjust their target capital structure The research is built based on the trade-off theory and pecking order theory We test whether these theories are relevant when applied to enterprises in Vietnam The study runs regression according to Pooled OLS model, the random effect model (REM), and the fixed effect model (FEM) to test and compare to find a suitable model through checking multicollinearity, automatic correlation and variance change From there, analyze the factors affecting the capital structure of non-financial enterprises on the Vietnamese stock market Finally, the speed of adjusting the debt ratio to the target level is tested by the Pooled OLS static model and the GMM dynamic model to test the homogeneity of the study The descriptive statistics show that leverage constitutes 36,9% of the capital structure of non-financial firms, while leverage is dominated by short-term leverage The speed of adjustment to the target capital structure is determined using both pool OLS and GMM to ensure the robustness of the finding I observed that profitability and asset structure were negatively related to leverage while the size of the firm and nondebt tax shield were positively related to leverage The regression results also give found that while profitability has a negative relationship with the debt ratio, size and iii growth opportunities are directly proportional to the debt ratio The adjustment speed of the capital structure of non-financial firms is now 32.7% which compares well with studies on non-financial firms done in most developed countries Keywords: Financial leverage, Business results, Target capital structure, Adjustment speed iv PLEDGE I reaffirm the thesis " THE IMPACT OF PROFITABILITY ON CAPITAL STRUCTURE AND TARGET CAPITAL STRUCTURE ADJUSTMENT SPEED: THE EMPIRICAL STUDY OF LISTED COMPANIES ON THE VIETNAM STOCK EXCHANGE " is my article and there are no copies from other authors' material This thesis is the author's research work, the research results are honest, in which there are no previously published contents or the content made by others except for citations fully cited in the thesis I will take full responsibility for my pledge Author Vu Pham Trung Hieu v THANK YOU First, I would like to thank all the teachers at the Banking University of Ho Chi Minh City for providing and supporting me with the necessary knowledge during my study at the school Such knowledge is the luggage that helps me to complete the thesis In particular, I would like to thank my instructor, PhD Duong Thi Thuy An, who helped me in the process of completing my thesis as well as guiding me to correct my shortcomings I would also like to thank my family and friends who have been by my side and supported me during this time Due to limited practical experience and time, the thesis cannot avoid errors I look forward to receiving your comments so that I can complete my thesis Finally, I would like to wish the teachers of the Banking University of Ho Chi Minh City, have a lot of health and achieve much success in work as well as in life Author Vu Pham Trung Hieu vi TABLE OF CONTENTS ABSTRACT…………………………………………………………………… ……iii PLEDGE…………………………………………………………………………….…v THANK YOU…………………………………………………………………………vi TABLE OF
