This study investigates the structural challenges hindering Indonesia's transition toward an innovation-driven, high-income economy, focusing on the interconnected roles of human capital, productivity, and technological capability. Using a mixed-method approach that combines 2SLS econometric modelling with extensive qualitative evidence from national focus group discussions across universities, government institutions, and industry stakeholders, the study finds that weaknesses in education quality, fragmented talent pipelines, and persistent gaps in university-industry collaboration significantly suppress Indonesia's innovation output. The quantitative results demonstrate that human capital exerts a strong causal influence on productivity and income, yet its impact is constrained by weak R&D ecosystems and low patent generation capacity. Qualitative insights further reveal systemic misalignment across education policy, labour-market demand, and research commercialization, producing a “human capital paradox" in which increased educational attainment does not translate into proportional economic gains. These findings underscore the urgent need for an integrated national strategy that simultaneously strengthens foundational education, expands R&D capacity, and builds cohesive innovation ecosystems to accelerate Indonesia's escape from the middle-income trap.
