“…It is worth that this study can be one of the first of its kind in current literature analyzing the interaction effect of stock liquidity and the family's ownership on capital structure, especially for the ASEAN region. In addition, this paper, exclusively for the capital structure, is profoundly different from all previous studies of determinants of capital structure in Vietnam's market (Dang, Ly Ho, Dzung Lam, Thao Tran, & Vo, 2019;Moussa & Elgiziry, 2019;Thanh & Mai, 2017;Tran, Hoang, & Tran, 2018) where it employed several measurements of three types of market liquidity, two proxies of leverage, and various dimensions of family controls to secure the results and robustness to robust results for the analysis. Lastly, the panel data sample's potential bias will be solved efficiently by using a new modern technique of panel quantile regression.…”
