The study used different regression methods using the data collected at enterprises listed on the stock market in Vietnam over the period 2008 - 2018, with 2937 observations. The research results find that the size of the Board of Directors, the independence of the Board of Directors, the percentage of women participating in the Board of Directors had a positive influence on FV.

This article studies the impact of working capital management (WCM) on firm profitability (FP) in Vietnam. The study uses the Generalized Least Squares (GLS) regression method using a sample of 5,295 firms (observations) listed on stock market in Vietnam from 2009 to 2018. First, the study found that inventory turnover, average receivables (AR), average payment (AP), cash conversion cycle (CCC) had negative impacts on the firm profitability (FP). However, when we continued using quadratic function, we found that INV, AR, AP and CCC had a non-linear relationship (the U-curve) with FP. These research results contribute managerial contributions for firms in efficiently using capital when considering its investment policy.
