This study is aimed at explaining relationship between working capital management and profitability with Vietnam empirical evidence. We selected a sample of 34 construction companies listed in the Vietnam stock exchange for the period of 2007 -2015. We found statistically significant negative relationship between the cash conversion cycle with profitability and also found statistically significant positive relationship between the debt ratio and the fixed financial assets ratio with construction companies’ profitability. The results have the special meaning to construction companies in which Vietnamese construction companies doing business in the Vietnamese economy have their own characteristics.
