摘要

The Nigerian construction industry is largely based on linear and unsustainable approaches, which have resulted in housing deficits, affordability problems and environmental degradation. Though MC contributes to global sustainability, there is limited empirical evidence from developing countries such as Nigeria and its association with SDGs. Underpinned by integrating the triple bottom line (TBL) theory and innovation diffusion theory (IDT), this study fills this gap by critically examining how the adoption of MC in housing production contributes to achieving SDG 9 (Industry, Innovation, and Infrastructure), SDG 11 (Sustainable Cities and Communities), and SDG 12 (Responsible Consumption and Production). The structured questionnaire was used to collect 124 data from construction experts using purposive and snowball sampling. With a reliability index of over 0.70, the gathered data was analysed using frequency, percentage, mean score, coefficient of variance (CV), Kruskal-Walli’s test, and Spearman correlation analysis. The study found that the environmental and social benefits of MC have a significant, positive impact on the SDGs 9, 11, and 12. The economic benefits exhibits no statistically significant relationship with SDG 9 and SDG 11 but has a weak statistically significant relationship with the attainment of SDG 12. The novelty of this research is the development and empirical validation of an integrated TBL–IDT framework that quantitatively correlates the environmental, economic and social benefits of MC to the achievement of SDGs 9, 11 and 12 in a developing context. The study advances knowledge on MC and proposes a decision-making framework for the delivering SDG-aligned sustainable housing.
