Middle-Income Trap: A Review of the Conceptual Framework

This study aims to review and synthesize the existing conceptual frameworks on Middle-Income Trap highlighting key dimensions such as structural transformation, innovation, governance, and human capital. It adopts a qualitative conceptual review approach, analyzing major theoretical contributions from World Bank, Asian Development Bank, and academic scholars. It compares models and frameworks across regions and critically assesses their strengths, weaknesses, and applicability, particularly for economies like Malaysia. The review shows that existing frameworks provide valuable insights into the causes of the Middle-Income Trap, particularly the roles of innovation, institutional quality and structural transformation.
However, most frameworks rely mainly on GDP per capita as a measure of the trap, and pay less attention to political economy, environmental sustainability, and digital transformation. As a conceptual paper, the study does not include new empirical data or case studies. Future research should validate the proposed frameworks through quantitative analysis or comparative case studies. In addition, this study relies on published literature and may not fully reflect the latest policy developments in all regions. This paper provides a clearer understanding of the multidimensional nature of the middle-income trap. It offers guidance for designing policies that integrate institutional reform, innovation systems, education, and inclusive growth.
