With the accelerated digital transformation of global society and the surge in demand for high-speed, reliable broadband connectivity, telecommunications operators face unprecedented pressure to upgrade their broadband service ecosystems. This study focuses on China Unicom’s broadband business, exploring strategies to enhance the modernization level of its value chain, supply chain, and industry chain. Through a combination of linear programming-based value chain optimization, quantitative risk assessment, and digital twin-driven supply chain management, we address key challenges including inefficient resource allocation (29% redundancy in network infrastructure deployment), inadequate supply chain responsiveness (average service restoration time of 8.3 hours), and low independent innovation in core broadband technologies (only 18% of key protocols developed domestically). Implementation of the proposed framework resulted in a 31% reduction in operational costs, a 47% improvement in supply chain resilience, and a 23% increase in broadband service satisfaction. The findings validate the effectiveness of integrating data-driven decision-making, collaborative innovation, and digital technologies in strengthening the competitiveness of broadband service providers. Quantitative analysis of operational metrics and risk factors provides actionable insights for industry practitioners aiming to navigate the complex broadband ecosystem.
