Circular Supply Chain Design for Sustainable Localization of High-Technology UAV Systems in Emerging Economies

High-technology supply chains are increasingly concentrated in advanced economies, limiting the industrial upgrading potential of emerging regions. At the same time, growing sustainability pressures require the integration of circular economy principles into production systems. However, existing research rarely integrates supply chain localization, circular value creation, and regional capability within a unified framework. This study addresses the following research question: how can circular supply chain design be structurally integrated into high-technology localization strategies to support sustainable industrial development in emerging economies? To answer this question, the study develops an integrative conceptual framework through the synthesis of localization theory, circular supply chain design, and capability accumulation literature. The framework is structured around three interdependent structural dimensions (SDs): (1) core technological supply chain processes, (2) circular value creation mechanisms, and (3) regional capability accumulation pathways. The framework embeds circular mechanisms—such as modularity, repairability, remanufacturing, and lifecycle management—within the supply chain architecture, enabling the transition from linear acquisition models to lifecycle-oriented systems. It provides an analytical basis for understanding circular localization and offers practical insights for policymakers and firms seeking to develop sustainable high-technology supply chains in emerging economies. This contribution advances the integration of circular economy and localization strategies and supports sustainable industrial transformation.
