Indonesia’s growing role in the global halal economy highlights the necessity of a well-developed halal infrastructure that ensures product integrity, strengthens consumer trust, and enhances industry competitiveness. However, existing studies and national practices tend to focus on isolated elements such as certification or logistics, resulting in fragmented implementation and uneven institutional capacity across regions. This study aims to provide an integrated analysis of halal infrastructure covering certification governance, halal laboratory networks, halal logistics, and digital traceability systems and examine how these components collectively reinforce the Sharia economic ecosystem in Indonesia. The analysis also considers how national regulatory frameworks shape institutional coordination, stakeholder roles, and system-wide governance of halal assurance. Using a qualitative Integrative Systematic Literature Review (SLR) supported by policy reports and empirical case documentation, the study synthesizes Institutional Theory, the Resource-Based View, and the maqāṣid al-sharī‘ah framework to analyze structural, operational, and ethical dimensions. This integrative SLR approach is employed to consolidate fragmented interdisciplinary scholarship and construct a unified analytical model of halal infrastructure. The findings show that coordinated institutional arrangements, capacity development of laboratories, and digital integration significantly enhance efficiency and credibility, although disparities remain in regional access and SME readiness. The results also demonstrate that regulatory alignment and multi-stakeholder collaboration are critical determinants of ecosystem performance. The study concludes that holistic infrastructure development is essential for sustainable and inclusive Sharia economic growth, grounded in the normative principles of halal–ṭayyib, maṣlaḥah, and institutional accountability, contributing a conceptual framework to guide future policy and empirical research.
