The moderating effect of operational performance on the relationship between quality management and corporate financial performance: Evidence from listed food manufacturing companies in Vietnam

This study examines the effect of quality management on the financial performance of food processing companies listed on Vietnam's stock market. Using OLS estimation and hierarchical regression, results show that firms with ISO 22000 certification perform better financially. Operational performance significantly impacts financial outcomes, with production flexibility and cost efficiency negatively affecting financial performance, while inventory turnover has a positive impact. Additionally, cost efficiency and inventory turnover moderate the relationship between quality management and financial performance, suggesting that ISO 22000-certified firms with efficient costs and faster inventory turnover achieve superior financial results.
