Intellectual capital (IC) is acknowledged as a source of wealth creation, thereby fostering competitive advantage and sustainability within the business domain. This study aims to conduct an empirical investigation to examine the impact of IC and its components on the sustainable growth of Indonesia Stock Exchange-listed manufacturing companies. This study employs multiple linear regression to examine data pertaining to Indonesia Stock Exchange-listed manufacturing companies from 2020 to 2022. It has been confirmed that intellectual capital promotes sustainable development, according to the findings of the research. Likewise, it has been observed that the elements comprising Structural Capital Efficiency (SCE) and Capital Employed Efficiency (CEE) encourage sustainable growth. However, different results are shown by Human Capital Efficiency (HCE), which indicates that HCE is unable to influence SG. The outcomes of this study offer valuable perspectives on the crucial components that can bolster sustainable growth in developing countries.
