Difference in Difference method and compares the debt- equity ratio of treatment and un-treatment (control) companies before and after this policy to determine the impact of corporate taxes’ change on firm’s capital structure The treatment group is state enterprises and otherwise is control group The data is collected in the period from 2001 to 2007, therein data related to the period 2001- 2003 is pre-treatment data and those in the period 2004-2007 is post- treatment date Similar to prior capital’s literature, the empirical results expose that that taxation actually has impact on leverage The measured impact is approximately -4.1 percentage point, meaning that with the introduction of incentive tax policy, the debt ratio of companies reduces more than percentage point The evidences also indicate that the large companies absorb the effect of tax change more than Small and Medium Enterprises and also are high significant level LIST OF TABLES Table 1: Variables’ definitions and

has used debt in its capital structure and the amount of the debt within the permitted level that the lenders cannot demand a higher interest rate, it will take advantage from the debt tax shield Since the cost of lending (proxied by interest) is deducted before calculating taxable profits, reduce profits, thereby, reduces the corporation tax of income that businesses must pay Some studies found the empirical evidences to support that taxes effect on capital structure However, it exists not less debates around this theory From the very first days of capital theories, Modigliani and Miller (1958), Miller (1977) and DeAngelo and Masulis (1980) desired to measure the impact of debt tax shield on corporate financial decisions They found the evidences suggesting that the more companies use debt to finance business, the more their own capital structures change related to tax benefit To the recent papers (Panier, Perez-Gonzales, and Villanueva, 2012; Princen, 2012; Faccio, Xu, 2015; …), these authors supply empirical results that tax benefit from debt tax shield effects firms’ leverage Princen (2012) used Difference in Difference model for the period 2001- 2007 to present that an equal tax treatment between debt and equity encouraging companies to use 2-7 percent less debt than a traditional tax system Panier, PerezGonzales and Villanueva (2012) approached in another aspect that is the equity ratio (the ratio between equity value and total assets) and showed the equity ratio of Belgium firms substantially rising from 32.6 percent in 2004 and 2005 to 34.2 percent in two following years In this case, 2004 is the year the tax reform had been valid Vietnamese corporate tax rules can be considered as a traditional tax system (Graham, 2003) Companies are taxed on their profits (the business income less the costs to generate that income) Those business that related costs included in the interest paid as return to the creditors Since these interest expenses reduces taxation income (tax deductibility) However, the returns to shareholders or 10 Figure 32- Panel E: Investment Trend over time of Investment 1,2 0,8 0,6 0,4 0,2 2001 2002 2003 20042005
