This study aims to determine the effect of working capital management on

company profitability and the moderating role of family ownership in the effect of

working capital management on company profitability. Using a sample of 218

manufacturing companies on the Indonesia Stock Exchange in the 2018-2021

period with unbalanced panel data, the research model was estimated using the

fixed effect model (FEM), random effect model, and generalized method of

moments (GMM). The regression results show a significant negative effect of CCC

on ROA and ROE, explaining that effective working capital management can

increase firm profitability. In addition, it is also found that family ownership

significantly strengthens the negative effect of CCC on ROA. However, the

moderating effect was not found on the effect of CCC on ROE.
