This study examines the effect of accounting quality, debt maturity structure, and accounting prudence on optimal investment in manufacturing companies listed on the Indonesia Stock Exchange (IDX) during 2019–2023. Using purposive sampling, 46 manufacturing companies were selected as the research sample. This descriptive, quantitative study applies multiple linear regression analysis processed with SPSS. The results show that accounting quality has a positive effect on optimal investment, debt maturity structure has no significant effect, and accounting prudence has a negative effect. Simultaneously, all three variables significantly affect optimal investment. These findings highlight the importance of accounting quality in reducing information asymmetry and improving capital allocation, while excessive prudence may constrain optimal investment decisions.
