Role of Management of Working Capital Items in Explaining the Operational Efficiency of Companies Listed on the Tehran Stock Exchange

Working capital management is crucial for business growth and survival as it maximizes enterprise value and shareholder wealth, thereby maintaining competitive conditions and optimal performance. This study identified and explained accounting variables determining operational efficiency (OE) of the companies listed on the Tehran Stock Exchange (TSE), Iran, in light of working capital items. The statistical population consisted of all companies, and the samples were 112 cases listed during 2016-2020. Utilizing an applied, descriptive-correlational research design, the relationship between the variables was then established. The dependent variable was OE, evaluated using data envelopment analysis (DEA); and the independent ones were working capital items and dividend growth rate. To investigate the effect of the independent variables on the dependent one, eight hypotheses were formulated, and multivariate linear regression with panel data in a fixed-effects model was implemented. Testing the hypotheses at a 95% confidence interval demonstrated that average period of collection of claims, average debt repayment period, dividend growth ratio, cash holding level, and liquidity ratio have a significant positive effect on OE. Nevertheless, the cash conversion cycle, and average inventory turnover period have negative impacts. Managers are thus suggested to identify working capital items and exploit them along with short/long-term goals in companies. This is practical in evaluating financial flexibility and solvency, facilitating optimal liquidity, and increasing business profitability and performance. Furthermore, learning about such items is helpful to investors, creditors, and analysts to make optimal decisions.
