This paper investigates the impact of capital structure on firm performance using a sample of 3,122 observations of 446 non-financial listed companies on the Vietnam stock market during 2011-2017. Using firm performance measures, namely ROE and Tobin Q, we examined if higher leveraged firms are more efficient or less in their performance. We employed the fixed effect model to prove that there is an inverse U-shaped relationship between leverage and ROE, and then we can find a preferred capital structure for Vietnam non-financial firms. To deal with endogeneity problem of the leverage variable, we employ two stage least squares (2SLS) regression with instrument variable estimators, which helps us strengthen the above results.
